Verify, validate, standardize, auto-complete, and cleanse your address list with PostGrid’s CASS & SERP-certified address validation API in real-time. Use our Standard API to Verify US & Canada Addresses. Use our Global/International Address Verification API to verify, validate, standardize, auto-complete, and cleanse addresses in real-time across 245+ countries.

An address verification service API helps you verify, validate, standardize, parse, geocode and provide a lot of other metadata related to an address adhering to local postal standards.

An Address Validation API is a service that lets you access the authoritative USPS database which has 160 million postal delivery points and 41,704 ZIP codes. It processes your mailing addresses to determine whether they refer to real places. Otherwise, it lets you spot the incorrect components, which you may ask your customers to modify.

Technically, the Address Validation API is an application programming interface, or API, that validates all postal information automatically. So it identifies address elements, standardizes your delivery locations for shipping, and replaces incorrect data with correct details. Also, it finds the accurate latitudes and longitudes for the addresses via geocoding.

You can integrate an Address API with databases, websites, CRMs, online platforms, and software programs and enrich your mailing list quality.

PostGrid’s API is CASS (Coding Accuracy Support System) certified, helping us build on USPS’s official address data to provide standardization, validation, geocoding, and autocomplete at lightning speed. You can use it to reduce delivery delays and enhance deliverability predictability to improve your customer experience. US address APIs normalize addresses to match the standards of the USPS.

PostGrid’s Address API plays an important role in ensuring the addresses entered are cleansed, accurate, and standardized according to local postal standards for higher accuracy and clean address data for your records.

In many instances, a user is bound to have errors while entering an address on your website or uploading a list with multiple addresses such as missing suite number, wrong postal address, or other types which can cause a lot of confusion, and wasted hours, and resources. An address verification software can eliminate this hassle and have clean addresses that save time and money.

Our address verification software allows you to verify, validate, or standardize addresses in real-time at the point of entry or allows you to verify in bulk allowing you to verify up to 200,000 addresses at once.

Our Address Validate API integrates with your enterprise system or CRM (primarily your website) to fetch the data and match it with your provided country’s postal address verification web service. Using this, you can ensure you have clean data right at the point of entry, reducing the bounce rate of your mail.

An API for address verification can help your companies in a lot of ways and double your returns. Some of them are mentioned below:

Saves Time

Once you merge PostGrid with your CRM or other systems, the API works automatically depending on the instructions you have set. From letting only correct and accurate data enter your system to cleaning and updating the customer details, PostGrid does it all automatically.

This way, you get to save a lot of time that you might have otherwise spent collecting and matching the data with the official database manually.

Enhance Your Conversion Rate

The faster your customer reaches the call to action, the better your conversion rate will be. The address validation API provides the address suggestions as your customers start typing their addresses.

It lets your customers and prospects fill in their details at a better speed and take them to the final CTA more quickly.

Plus, it also ensures that they only enter the correct address. For example, as an individual starts typing their address details, PostGrid will recommend a number of addresses depending on the area and zip code they’ve entered. It’ll force them to choose one of the suggested addresses.

If they fail to do so and the API doesn’t recognize the address they have typed, they’ll have to change it and choose the correct address. This way, you can guarantee the order’s shipping and delivery to the right address on time.

Cost-Effective

Over the years, things have changed vastly, and technology has advanced way too much. Similarly, no company in the business of sending regular direct mails would be willing to do it the traditional way.

The old ways are not only time-consuming but cost a lot too. With an automated API in place, you can eliminate all such methods and the money you’d otherwise spend operating in those ways.

The Address Validate API stores the instructions given to it and manages the tasks quickly and accurately. This way, you save money from the beginning of the tasks. However, for some reason, if your customer returns the parcel and you need to send a different package to the same address, you can do it with a few clicks without entering every detail again.

Improve User-Experience

When your customers or potential customers visit your store, they judge it by the interior of walls, furniture, staff, and of course, the quality of your products.

Similarly, when someone visits your website, they check out how it represents your brand, how easy it is to find things there, and the user-friendly features you have displayed.

A good company will always try to make their user’s journey a cakewalk on their website. Hence, you must use such features that enhance the user experience and enable them to place an order quickly.

The API for address validation can help you do it just by its integration with your CRM.

High-Quality Data

The address API, like PostGrid, offers you at least three features: address parsing, standardization, and validation. By parsing and standardizing the data present in your mailing list, API makes sure that the data is available in the right format. By validation, it ensures that the addresses are correct as per USPS guidelines.

Plus, the USPS address validation web service keeps on updating with the new location details. Hence, PostGrid keeps on updating your mailing list accordingly. Besides that, as you grow, new addresses keep on filling your mailing list. With entry-point verification, PostGrid makes sure that only the correct data enters your system.

This way, the data in your mailing list is always of high quality.

International Supplies

When you’re in a business where you have to send parcels, packages, and direct mail pieces overseas, nothing changes for shipping it to the correct address except for fear of damage.

When you send something locally or even within the same nation, you have a thorough knowledge of the addresses’ format and other details.

However, it’s not the same for the international addresses. Every country has its own laws, making it difficult for you to follow up.

PostGrid has databases of over 150 countries, allowing you to ship to the right address confidently without fearing the loss you might have to face on the loss of your direct mail pieces.

Plus, just like you can automate the shipping of your direct mail pieces in the US, you can also automate them overseas.

Without proper market research, businesses don’t mindlessly choose a third-party address verification API. There are a lot of factors that you need to consider while making the final call for your business. We recommend you follow these points; 

Cost of the Solution 

Save your money on something other than an unreliable address verification solution. It would help if you had a cost-effective solution when you want results in the long run. The solution must fulfill your business needs and give you the guarantee of accurate results. 

Avoid falling for affordable software, but consider options that integrate well with your existing systems. Otherwise, you have to spend additional resources and time on integration. We want to advise something that gives you flexible pricing options. 

How Accurate are the Results? 

Accuracy is another vital factor you must ensure from your verification API. It should rely on the USPS official address database and consider additional databases for verification. Also, look for a solution that considers NCOA for verifying addresses accurately.

Automation Features 

Manual processes to verify addresses will compromise your business efficiency and productivity. It would take additional time and staff to verify addresses manually. The address checker API must provide automation features to reduce friction in verifying addresses while keeping costs low. 

Integration Capabilities 

It is another vital aspect to consider when selecting an address API. When you choose the best solution, you will get integration capabilities with almost every tech stack, CRM, marketing automation tool, logistic software, etc. This capability will enhance your productivity rate and efficiency levels.  

The Convenience of Use 

An address checker API must not require you to invest in additional training and extensive time. Look for something that provides an easy-to-use user interface without any complications. The goal is to save time while maintaining efficiency. You cannot invest time in something that has a long learning curve. 

Reliability Factor 

Consistent performance and uptime are other priorities while looking for an address verification tool. Otherwise, you can compromise your business processes and disappoint the customers. Draw comparisons between service providers to understand the uptime and availability factors. 

Data Security 

An address verification service provider must ensure top-notch data security. After all, you will trust the provider with all your customer data. Any novice service without any security measures is giving an invitation to identity theft, fraud, malicious attacks, or even legal consequences. Therefore, it is vital to consider a third party that hosts its data on secure servers and ensures compliance. 

Frequency of Database Updates 

Do you want the verification to take place against the latest database? If yes, look for a solution that regularly updates its database with the most recent address changes. It will save you from obsolete and undeliverable addresses. Make your address verification process accurate by relying on the latest database.  

Customer Support Availability 

Even USPS doesn’t provide chat support and reliable phone support to resolve address verification concerns with their APIs. It would help if you considered a solution that gives you customer support and a dedicated account manager to help you with your problems and queries. 

Ability to Handle Typographical Errors

People are bound to make errors while typing addresses into an address field. Try to find a solution that explicitly fixes typographical errors in every form. It will help your business save time in rectifying spelling mistakes. 

An address validation API can process, change, or manipulate addresses to make them more accurate and valuable for businesses and customers. However, there are various types of APIs that you should know about. 

Address Correction API

This type of API usually searches for addresses in an authoritative or official database to rectify typographical errors, abbreviations, and casing. A government entity usually runs an official address database for mail delivery purposes. Traditional databases can aggregate data from multiple sources to provide completeness instead of only achieving a specific goal. 

Address Validation API

These APIs run validation to confirm if an address is legit or deliverable for specific purposes. In America, the USPS manages the entire database for the nation. Thus, users can access all the information by using their APIs. However, there are a lot of limitations if you consider using their official API. 

Thankfully, USPS allows third-party providers to develop their APIs by relying on the USPS database. It is vital to note that although USPS processes international deliveries. Yet, it does not provide global address verification capabilities. For this reason, it would be more sensible to use a third-party address validation API. 

Address Enrichment API 

You can obtain additional information on each address when you use address enrichment APIs. FIPS codes, congressional districts, and vacancy status are some extra information you can gain using these APIs. Organizations and marketers can use them to gather information for marketing and business decision-making. 

USPS ZIP Code API

Businesses use these APIs to fulfill multiple purposes. They can help you verify whether an address has a legitimate ZIP code assigned to it. Many use these APIs for appending ZIP codes to incomplete addresses. Because the concept of ZIP codes only works in the United States, a ZIP Code API will only work with addresses in the country. 

Address Standardization API 

These solutions convert the addresses to USPS standards or specific formats of other countries. There are many options when you want to use an address standardization API. For example, Google’s API can help you address validation and standardization. However, the search engine giant won’t standardize results in autocomplete, mapping, geocoding, or other mapping solutions. 

Address Autocomplete API 

As the name suggests, an address autocomplete API automatically provides suggestions while the user starts typing. It saves users time and prevents them from typing an incorrect address. Instead of typing the wrong address, users are more likely to click on the suggestion. 

Since the recommendations will show an adequately formatted and validated address, you will always maintain high-quality addresses in your database. It also dramatically reduces the chances of cart abandonment as the user doesn’t need to write locations word by word. 

Address Verification API 

A proper API for address verification will provide you with all the features of these other APIs in a single package. Businesses can verify, validate, cleanse, standardize, autocomplete, and obtain additional address information. PostGrid API improves your deliverability, keeps you updated with records, and eliminates return mail. You invest in a single solution but get the power of all APIs! 

When to Use an Address Verification API? 

There could be goals for using an API for address verification. Some businesses prefer using it to ensure deliverability, while others for marketing. At the same time, some entrepreneurs also use it for business intelligence. Let us discuss the possible use cases of an address API; 

• Checking the existence of an address: You often need to check whether a specific address exists. An address API will verify the location and provide a standardized version.  
• Verifying the complete accuracy of an address: Many businesses want full assurance of the genuineness of addresses before using them. Address APIs can ensure that your locations are valid and genuine. 
• Ensuring correct delivery address before mailing packages: You can also improve delivery rates and avoid delays and failures by relying on an API for address verification. It will verify whether the address is deliverable and accurate. This use case is ideal for shipping and e-commerce companies that must verify shipping addresses for dispatching packages. 
• Improve efficiency and reduce costs: Ensuring accuracy before delivery can decrease additional charges and save time in shipping. Many businesses can reduce their expenditure with the help of an address API. 
• Increase and preserve your reputation: A business having shipping and billing errors due to inaccurate address data can damage its reputation. More customers will show their disappointment with bad ratings and reviews. Address API can save your reputation with accurate and consistent information. 
• Reduce or prevent fraud: Critical industries like finance and insurance often use APIs for address verification to get protection against fraud and identity theft.  
• Prepare an address for geocoding: It helps ensure the legitimacy of locales before you prepare them for geocoding.

After studying the benefits of address API, you can determine how much loss the lack of a proper verification API can do to your business.

By sending your mailpieces to the wrong addresses, you can hurt your chances of increasing sales, deepening bonds with your customers, and nurturing or delighting your current clients. Apart from that, you also lose the money, resources, and time you put into it.

Manually standardizing and validating the addresses can be time-consuming and tiresome. Being tedious tasks, they can let you slip on a few errors, like typing, spelling, or formatting mistakes. That may affect your brand’s reputation considerably.

Hence, you must clean the data of your mailing list regularly and keep a check on the wrong information from entering your system. You can solve all of such problems with a single PostGrid API.

Moving forward, we’ll discuss how you can easily and effectively use one such API to drop the time, money, and resources you put into a direct mail campaign and get better returns.

Address verification API works by integrating with your system to check and correct all the address data. It can also instantly verify any address that you have entered and provide you with a whole lot of other metadata such as Latitude/Longitude, Geo-coordinates, RDI, ZIP+4, and many more.

Our API is both CASS (USPS) and SERP (Canada Post) certified which ensures all addresses are cleansed, verified, and standardized to local postal standards.

Our Address Validate API can be integrated in the following way

• Create an account with PostGrid – Enter the required details and get your account ready in just a few minutes. The set-up is very self-explanatory and quick.
• Login – Login into your account with your unique user ID and password. A go-to dashboard will be made accessible to you, which will contain everything that you need to use the API.
• Use the API keys – Your test and live API keys will be available for you through the settings menu. You will have to copy the keys from here. It is recommended that you use these keys only on trusted servers to ensure maximum security.
• Paste the keys – The next step will be to paste the URL of our validation API to your website’s address form, where you want the addresses to be verified.
• Start API calls – Once you paste the URL, you will receive successful API calls on request. You can even customize it according to you. If you get stuck at any stage or the API is not responding in the way you need, feel free to contact us, and we will help you out instantly.

How Does Address Validation API Work with USPS?

The United States Postal Service is one of the largest postal service providers in the world. Every day, they handle millions of posts throughout the country. The postal service is famous for maintaining an address database of over 160 million mailing addresses in the US. They update it monthly to keep the data relevant and fresh.

You can find millions of delivery points for businesses, residents, and post office boxes. Apart from this, there are several metadata points, such as delivery point code, county, and vacancy status.

Indeed, USPS has a vast database of addresses, but not everyone can access this data. Certification is necessary to gain access to the data and verify addresses with the USPS database. The postal service provides official address APIs and web forms for users.

You can also access this massive pool of data through third-party providers. However, these providers must comply with the stringent rules to become CASS-certified vendors.

Vendors like PostGrid can use and enhance USPS address data for multiple use cases that you won’t be able to do through USPS APIs. When you use their official APIs, you cannot download their database with ease. It will take considerable investment and enormous effort and lead to a violation of their terms of service. The actions and risks are too high to afford!

PostGrid allows you to download its entire US address database with ease. USPS can have a 160 million US addresses database, but we have even more with third-party postal services and data providers. It gives you more reach in the market with more possible addresses.

However, don’t worry; we primarily run our address verification process against the USPS official database.

Here are the steps of how PostGrid Address Validation API works:

• To get started with PostGrid’s Address Validation Service API, you’d need to integrate it with your CRM, website, or other systems.
• Once integrated, it’ll fetch all of the customers’ details present in your database.
• After collecting the data, it’ll parse each of the customer records present in your mailing list. By parsing, it means breaking down the different components of an address to make it clearer.
• Next to data parsing, it’ll standardize all of the records. It means changing the formatting according to the guidelines of USPS.
• Once all of the separate customer addresses are in the right format and are CASS certified, the API will validate each of the entries with USPS’s official database.
• Besides, it lets only accurate and valid addresses enter your system once integrated. Thus, keeping the quality of your mailing list high and keeping the spam away from your system.
• For entry-point data cleaning, the API suggests valid addresses to the prospects as they start typing in the empty field. Gradually, as they continue to type, the recommendations get better and more exact. Now at the end, they can select the right suggestion and save it.
• If the prospect fails to select one of the suggested addresses, the address correction API will not let them move to the next step, and they will need to locate the error they’re making and fix it. This step ensures that only correct data enters your system.

You can also do it manually by following these steps:

• Collect all the entries of customers from your system’s data that you want to validate
• Go through each record one by one, keeping the USPS guidelines in mind
• And parse, standardize, and validate your data

It might seem like a simple process, but it can be challenging to manage and verify tens of thousands of customer addresses without making any mistakes. Plus, it’ll eat up tons of your hours, resources, and money, and yet, it’s not clear whether your database will be error-free at the end or not.

An automated API can improve your address data-cleaning process tenfold and save you a tremendous amount of time. Plus, all your direct mail pieces reach the right recipient, reducing your misspending cost.

We all love USPS for its tireless efforts and innovative technology implementation. As a USPS-certified address verification service provider, it would be hard for us to talk about its limitations. Still, to give fair justice to our readers, we will educate you by discussing its shortcomings.

The API is Exclusively for Shipping and Mailing Services 

Every USPS address API could be accessible after registering with an account. Yet, the APIs strictly focus on shipping and mailing services. Even the USPS terms of service mention this limitation to its users. You cannot use their API for bulk address verification, database cleansing, or other innovative causes. Failure to abide by their terms of service will immediately terminate API access without any notice.

It would help if you had a more advanced solution to standardize your addresses, merge data or check with multiple databases. It is crucial if you are working with a massive volume of address data.

You might be missing out on your business’s most astonishing opportunities and ROI by relying on USPS alone. It brings us to the next challenge of USPS address APIs.

Limitations with API Documentation & Support

Although USPS APIs can do much with their massive database, the documentation could be more robust. You need help getting an SDK for their postal address APIs. It becomes necessary to code one line at a time.

There’s no shortcut that you can expect with USPS. Even chat support needs to be present with USPS address APIs. The experience is even more painful if you are considering phone support. 

API Uptime Status

Even though it is the official solution to access the USPS database, their APIs are famous for having inconsistent uptime. What can you expect when the answer comes for free? Reliability is a significant issue when it comes to using USPS address APIs. Chronic downtime issues and incomplete data are some colossal problems for business users. 

Data Completeness of Addresses

The primary objective of the USPS database is to support the mail delivery system in the country. Yet, they still need to get every single address in their database. Although they cover over 160 million residences and businesses, they still exclude millions of locations they don’t serve. 

Private delivery companies like Amazon, DHL, UPS, and FedEx include these non-postal addresses that the USPS excludes. If you want to ensure the legitimacy of your address information, regardless of USPS deliverability, you need to consider more fulfilling solutions than USPS address APIs. 

The lack of reliability, documentation, and restrictions makes USPS not a very suitable option for businesses. Developers and business professionals can do little with the official USPS address APIs. 

The Need for Third-Party Address Verification API 

The USPS address API focuses on organizing address data instead of sharing it with everyone. A third-party service provider would be a more reliable way to use the USPS data than using the official APIs. 

Many service providers use data from the USPS and complement it with additional information that could be useful for customers. A service provider like PostGrid gives you a reliable solution to use the USPS database and other vital sources to verify your addresses more accurately. 

You might be thinking, that tons of street address validations are available in the market. Why on earth do I choose PostGrid? Well, your question is valid and fair, which is why we’ll discuss a number of features, PostGrid offers that can change your life. Let’s find out what they are.

Global Address Data Verification

PostGrid global address API solves the problem that every postal address verification web service provider faces, the difference in language, script, and alignment of information. We have a postal database of nearly 245+ different countries. You can use our international address verification to verify addresses globally.

With PostGrid, you can translate each of the addresses that your customers provide, and get them parsed, standardized, and validated within minimal time. This way, you can ensure the right mail delivery, on time even across borders.

Geocoding

PostGrid’s Address Validation also returns reverse geocoding data like latitude and longitude coordinates with its geocoding API. It helps collect the accurate address details and ship the order to the right area without any confusion. If you integrate PostGrid with your CRM, you can quickly get your prospects’ complete information without them even typing it in. This feature also helps them reach the CTA more speedily and place their order.

Address Autocomplete, Parsing, and Standardizing

Address Autocomplete is, of course, the major feature of the PostGrid API. It fetches the entire data from your system within minimal time to parse, standardize, and validate it within milliseconds per record using autocomplete API.

Data Improvement

Along with identifying the correct, valid, and incorrect addresses, wouldn’t it be helpful if you could also manage to determine the “not yet built” area details?

PostGrid helps you know each one of them. So you can segment your audiences and ship your direct mail pieces only to the deliverable addresses, where someone is definitely receiving them. In other words, the address exists in real time.

Excellent Customer Support

With PostGrid, you can leverage customer services 24×7. Although the API is super simple to use — integrate it with your system, get the live API keys, and get started. Yet, if you face any difficulty getting your API keys or any other problem, you can contact us. We’ll provide a solution to your query within one business day.

Data Safety and Security

Privacy is the primary concern at PostGrid, which is why we have a direct partnership with HIPAA, PIPEDA, SOC-1, and SOC-2 compliant vendors. We guarantee the safety and security of your and your customer’s data. This way, you can make decisions undoubtedly.

Scalable Processes

One of the biggest mistakes that companies make is to validate their data once and think it’s good to go for ages to come. With the growing business, grows your mailing list, and you’d definitely need to parse, standardize, and validate the new addresses by scaling the process.

Plus, the data keeps on changing, which is why you’d also need to keep updating it in line with the official database of USPS. Hence, PostGrid provides a scaling feature, where you can verify as many addresses as you want and at any time.

System and Zapier Integrations

The major reason behind integration is the smooth user interface so you can manage and operate multiple software and applications with ease. When you integrate PostGrid with your system, you can perform numerous tasks, viz., data fetching, with a single click.

Similarly, we offer Zapier integration, which helps you to incorporate over 1600+ apps. This way, you can automate most of the tasks and functions.

Deduplication

One of the excellent features of PostGrid address API is that it detects similar customer details present in your system and removes them.

More than often, due to retargeting, most companies contain the record of a single prospect multiple times in their database. It results in sending several copies of your direct mail to a single potential customer.

Hence, you not only annoy the recipient but also cost yourself money, which goes into creating, printing, and shipping the direct mail. Plus, depending on the number of duplicate addresses present in your system, this cost keeps going higher.

That’s why de-duplication of the addresses is as essential as verifying the validity of the addresses. Apart from this, the validation API also helps remove all the information gaps, spelling errors, typing mistakes, and other similar errors from your mailing list.

Cost-Effective

Besides providing you with excellent features to reduce your investment and misspending and increase your returns, PostGrid offers competitive prices. Depending on your business type and size, you can choose a package that best suits your needs. We offer no hidden fees. You only pay for the options and features you decide to get.

Validate at the entry point: PostGrid assigns the DPV (Delivery Point Verification) codes to all the addresses as per the USPS API database. This feature checks the validity of the address your prospects are typing in the empty fields and gives them proper suggestions. This way, you keep and let enter only the correct addresses in your mailing list.

The LACS Link: Using the Locatable Address Correction System Link, PostGrid updates your database with the addresses changed or modified for emergency purposes.

The RDI System: Residential Delivery Indicator is a feature in PostGrid that helps you detect and separate the commercial address from the residential one.

SuiteLink: This unique feature enables the API to find and fix the apartment, floor, room, or suite number if your prospects provided the wrong or no address such information at all. This feature can save you from dropping the packages at the main gate of the building, exposing you to the chances of losing them. With this facet, you ensure the delivery of your direct mail right to the door of your recipient.

Intelligent Mail Barcodes: If you want to locate and track your shipped direct mail pieces, PostGrid helps you do it with Intelligent Mail Barcodes.

No more lost direct mail pieces:

If you start using PostGrid’s address standardization API, then all the addresses present in your database will be accurate without any data duplication or information gaps. Depending on the number of direct mail you send out and how often, you can save tremendous amount of money and time.

And since no mail is returning or getting lost on its way, the chances of lead conversion also rises with twice the speed as before, and subtracting the investment from the outcome; you can start seeing an ultimate boost in your revenue generation.

Best data quality:

By utilizing PostGrid Address Autocomplete API at the point of entry, you can ensure that the right address will enter your system. It not only saves you from sending direct mail to wrong or incomplete addresses but also from spam trying to enter your system.

Besides that, with regular cleaning, verifying, and updating your old data list with PostGrid, you can get a quality database within a few days.

Improved Communication:

Decreased mailing cost:

With better address quality, you automatically reduce wasted spends associated with returned mail or loss of mail due to incorrect addresses. Our address verification software will ensure your addresses are cleansed, verified, and standardized to local postal standards ensuring a smooth print and mail process.

Increment in overall process speed:

with a fast and on-the-spot Address normalization API, you can completely eliminate the manual work and speed up the process. As it takes around 3-5 business days to verify the collected addresses manually.

Faster turnaround time:

Scalable services:

You can verify as many numbers of addresses as you want. From thousands to millions of addresses, our address validation software helps our clients verify them all.

The primary use of the API is to ensure that the data entering your system is correct, free from errors, complete, and exists. Besides that, it also checks for other details and keeps the spam from entering your database, similarly, you can also check the already registered addresses in your system for accuracy. The API will analyze and match all the addresses with the standard data available in your country’s postal services in the case of PostGrid—USPS.

Here’s a list of the businesses that can use USPS address validation API:

• E-commerce platforms: All e-commerce sites need to deliver products to a number of addresses on a daily basis. And sending the mailers regularly to wrong shipping addresses can cost them way too much money, and eventually decrease their returns. Hence, an address verification service is essential for these companies to not only maintain their profit but also to gain high returns.
• Branding Personal Stores: Most businesses start to sell – the products available in their stores – online and offer shipping options to their customers for convenience. However – in an era of online payment – delayed delivery or sending the packages to the wrong address may ruin the stores’ reputation and cause business loss. That’s why most such companies contact us to get PostGrid to verify the addresses in their database.
• Third-Party Logistics: Some 3PL companies – that contract with online brands and other product-selling businesses for shipping their products – usually take postal address validation web services like PostGrid. These services help them serve their clients better with minimum returns.
• Short-term Rental Homes Service Sites: Most of the time, when a new user lists their property on a site like these, it becomes necessary to confirm the location to prevent the end-user from getting lost or having difficulty finding the homes. It’s especially essential for users opting to pre-book homes or hotels. Address Lookup API & tools like PostGrid help businesses gain the trust of their customers by providing them with accurate data.
• Credit Check Services: Banks or other financial services companies – which are not directly related to shipping mailpieces – can benefit from the address correction API like PostGrid to save money. To connect the people offering and needing a loan, the companies are required to do a credit check. And despite the accuracy of the data provided, they need to get the job done. That’s why PostGrid offers address validation software for a wide variety of businesses. It helps avoid misspending.

Address verification APIs can have multiple use cases across different industries. From reducing fraud to ensuring deliverability, they are helping many businesses optimize their processes. Let us examine a few examples; 

Retail and E-Commerce Companies

These entities implement API for address verification to reduce the friction in their checkout flows. Shoppers can get a much easier way to fix their addresses while ordering products from e-commerce stores. This way, businesses can decrease misdeliveries, delays, and failed deliveries.

Customer data plays a vital role in helping marketers to understand customer demographics, preferences, and pain points. Developing effective marketing plans becomes possible with the help of address APIs. When you have supplement data from address verification software, you can take additional steps to make your advertising plan effective. 

Despite the shortcomings of USPS, you must uphold the value of the postal service having a database of over 160 million addresses in the country. USPS relies on its Coding Accuracy Support System to support and give certifications to third-party address validation providers. It also improves the accuracy of postal coding, such as carrier route, ZIP+4, and 5-digit ZIP Code coding. 

We recommend you consider CASS Certified software for your address verification goals. It can fix spelling errors, standardize addresses according to USPS guidelines, and even add missing components to an address. 

An address verification API with CASS certification indicates better accuracy, higher response, lower costs, and other benefits.
