Real-time Address Verification & Address Validation Software

Our top real-time address validation software checks all the existing and upcoming addresses in your database and matches them with the address details available in the official postal service provider’s data.

An address validation system service verifies if a customer’s address is listed with major shipping carriers or not. The address verification process is generally used by eCommerce stores to reduce checkout errors, boosting conversion rates throughout the process.

The Address Verification System is a tool that allows merchants to verify the billing address provided by the clients or customers. It also adds up to the security when talking about customers with credit card accounts to avoid fraud.

With the help of our address verification software, you can check tens of thousands of addresses’ accuracy in seconds and ensure that the other data entering your system is correct and complete. So, next time you send any mailpieces to these addresses, you know that your money or resources are not going to waste, including the number of lost and returned direct mail will reduce significantly.

Let’s find out how the wrong address details impact your business growth.

How Do Wrong Addresses Cost Your Business in General?

address verification and validation api

Lost Sales Opportunities

When you send your mailer to the wrong address, the person who is meant to serve may not be able to receive the provision you offered in it. Chances are that the person was willing to go ahead with that offer, hence you missed a clear-cut sales opportunity here. Plus, if there are a number of wrong addresses in your database, the cost of lost sales opportunities multiplies tremendously. Eventually, this practice will cost you a lot of business.

Loss of Money

You may not realize it, but when you send your direct mail to the addresses it’ll cost you per month just for the postal address verification services. As the mailers will return and sometimes you’ll need to reship them because of some general typo in the address provided.

Additionally, if we talk about marketing direct mail then the wrong addresses will not only cost you the shipping fees but also the printing and personalizing costs. So, technically, one simple mistake is costing you significantly a lot of business growth and money.

Annoyed Prospects and Customers

You may think about how much a mistake can cost. In business, let us assure you—a lot. If you keep sending irrelevant offers or discounts to your unrelated prospects or customers because of a simple typo, they may get frustrated. And this frustration may result in them opting out of your services or never buying from you again. Hence, you lost some of the customers for life. And that’s a huge loss to the business. Especially when you know you’re sending thousands, if not millions, of direct mail regularly.

Loss of Resources

Have you ever noticed, that apart from money, a tremendous amount of physical and human resources are involved in direct mail marketing? When you mail a significant amount of mailpieces to the wrong or incomplete addresses, not just the money, the sales, and networking opportunities, but also the resources involved suffer a considerable loss. However, it can be avoided with the best address validation service tool, like PostGrid.

Ruined Brand Image

When you send mailers to the wrong addresses or with typos on them mentioned on the mailpiece envelope, you may face significant problems. The first problem is that direct mail is not only about marketing, but you use them to send letters too, and sometimes they may contain sensitive information in them.

Mailing such reports to the wrong address may get you in serious trouble, and the customers probably wouldn’t be willing to do more business with you. The second thing to note is that if you mail your prospects or clients with a typo in their names or addresses, they might think you’re not a professional, which may hurt your brand reputation.

They don’t have to spend time learning coding to facilitate integration. It allows professionals to manage customer information automatically without much manual effort. 

How to Select the Right Address Verification Tool for Your Business?

Choosing the appropriate address verification software depends on many factors, such as cost, accuracy, convenience, integration capabilities, and more. Market research, noting features, and drawing comparisons are vital to finding the most suitable solution for your business. Here are some tips you can consider; 

Consider the Implementation Cost 

After all, it is your hard-earned money, so it must be a noteworthy investment. The cost is the most critical factor to consider while investing in address verification software. An affordable solution is a must, especially when looking for a long-term solution. However, don’t only look for budget-friendly software but also a solution that fulfills your business needs. It would be advisable to get something that provides flexible pricing options.

How Accurate is the Solution? 

Only a few address verification software provide high accuracy by cross-checking with multiple data sources. The solution must verify information with official databases like USPS, Canada Post, Royal Mail, etc. Only ensuring that an address exists doesn’t mean it matches with other data of a user. Looking for a solution that runs multiple checks before providing results would be advisable. 

Ease of Use

There’s no point in spending hours learning how to verify addresses with the software. A user-friendly and easy-to-use tool will save you time and investment in training your team. There should be a dedicated dashboard for every option to verify addresses in real time without any learning curve. 

Compatibility with Existing Systems 

Your choice of address verification software should provide easy integration with your existing system. Look for a solution that gives compatibility with the maximum number of tech stacks, CRM software, accounting software, marketing automation tools, logistics software, etc. It would ensure that your workflows will be streamlined and efficient. 

Data Security 

You cannot trust anyone with your vital customer data. If you ignore this, you are inviting potential malicious attacks and even legal consequences. Ensure your address verification software provider maintains regulatory compliance and hosts data on secure servers. It would protect your customer information from fraud and identity theft. 


When investing in address verification software, look for solutions that provide consistent availability and performance. Look for reviews and customer testimonials to determine the reliability of the software. If you are getting poor availability and performance, it is a sign of upcoming problems. 

Automation Capabilities 

Manual verification of address takes a lot of time and effort. Businesses often don’t have the time or additional staff for a manual process. An address verification software must provide automation features to smoothen the verification flow and keep costs low. It will also decrease your waiting time for verifying addresses and obtaining customer information. 

Geolocation Capabilities with PostGrid

The address verification API by PostGrid also provides geolocation capabilities to pinpoint addresses on the map. Businesses can use this data for identifying geographic patterns, managing customer data, analyzing address data, personalizing services based on location, etc. You can obtain the corresponding coordinates (longitude and latitude) for each address from your database. It could be a remarkable feature to avoid fraud and delivery issues. Get confidence in each location from your lists.

Why Consider Investing in Address Verification?

As a business, you cannot undermine the value of reliable customer data. High-quality address data management should always have a top priority in your organization. Accurate address data is necessary for fulfilling orders, delivering marketing messages, receiving timely payments, and more. 

Vital address data can be missing or incorrect at the data collection point. It can lead to massive errors and confusion among your team. Even if you collect data correctly, the quality of this data may change over time. It will help if you stay updated with the latest address changes. 

The Negative Impact of Bad Address Data 

  • Increased material and packaging costs: An unreliable and inaccurate address database means increased return mail. You must invest more resources into material and packaging for redelivery attempts. 
  • Loss of Time and Higher Labor Costs: Bad address data makes you spend more time correcting and assigning more professionals to resolve discrepancies. Time and resources are vital for any business. 
  • Increase in Mailing and Shipping Costs: When you attempt deliveries in undeliverable addresses, you pay unnecessary mailing and shipping costs. Poor address data can extensively deplete your resources and provide no results. 
  • Cash Flow Problems Due to Late or Non-Existing Payments: The incorrect or improperly formatted addresses can lead to receiving payments and cash flow issues. 
  • Negative Impression: Delayed or lost packages are a big turn-off for customers of any business. Poor address data can be a significant contributor to this problem.   

Three Elements of PostGrid Address Verification Software 

The address verification process can take place in two steps; 

  • Upfront 
  • Referential 

An address verified is “upfront” when your customer fills in location information in a search field. Our API rectifies any problems with incorrect inputs or missing data during the search. The real-time verification feature prevents users from entering incorrect information with autocomplete suggestions.

An address verification process can also work retroactively, famous as “referential” purposes of validation technology. It occurs when a user enters an address; the system cross-verifies the data against postal information databases. It helps businesses in standardization, cleansing, or supplementing: 

Standardization: The address verification software ensures that input data meets the address format requirements of the respective postal service (USPS, Canada Post, Royal Mail, etc). It formats the address with appropriate abbreviations. 

Cleansing: The API works tirelessly to rectify typographical errors or incorrect address data. This way, businesses can ensure every address in their database is accurate and correct. 

Supplementing: If necessary, the address verification tool also provides missing components into the address data by a user. It saves time for the user and the business. 

What is the Difference Between Address Verification and Address Validation? 

PostGrid’s address verification API goes beyond standard validation of the existence of addresses. It gives you confirmation on whether or not an address is correct and deliverable by comparing it against official databases and third-party sources. The software will even fix addresses whenever necessary to optimize your address database. 

PostGrid with Superior Data Enrichment 

We help businesses with data enrichment to get third-party data for addresses and geolocations. It enables them to understand demographics, firmographics, or risk-related information. This information can allow you to make data-driven decisions for superior customer engagement, predictive analytics, and risk assessment.

The Impact of Address Verification Software on Sales

E-commerce and retail businesses must consider collecting accurate shipping addresses. Every customer expects the smoothest experience and faster delivery times. The moment a customer complete their purchase, they anticipate getting their package as soon as possible. 

Address verification software provides corrections in real time based on official databases. This way, your packages are always deliverable to the right customer. When you validate the delivery point, your business can increase conversions, enhance customer experience, and reduce delivery failures.

PostGrid For Address Correction: Fuzzy Error Prevention

At PostGrid, our intelligent fuzzy matching capability is the best on the market. We correct misspellings, complete abbreviations, and fill in the missing information. Below is what we deal with:

  • Spelling Errors: Our address verification tool can understand what you meant to write even if you do not know the spelling of words or accidentally hit the wrong key. Additionally, this can be extremely useful for internal systems where addresses are taken over the phone and spelled differently than the way they sound.
  • Switched or Misplaced Words: Typists are notorious for switching adjacent letters in words, as in Raod (Road) and Mian (Main). This is detected by our tool, and we can help you understand what your user wants. PostGrid’s address validation service will help you find your address even with missing words and letters.
  • Abbreviations or Nicknames: Our Restful API can even identify the correct address if words are shortened, using abbreviations – such as Blvd for Boulevard, or if you use familiar, regional names, even if the suburb has been absorbed into the city’s jurisdiction.
  • Dealing with Extra Space: Street names and places can be confusing because they can be made of one or two words, or maybe they’re hyphenated. Despite unclear spacing or accidental additions of too many spaces between words, our address correction or verification API locates the address.

PostGrid: Our Workings to Correct Address

We also help you validate incoming postal addresses in real time using our address API. Occasionally, customers forget to enter their apartment number or misspell their street name.

When you integrate address verification API, our servers check the customer’s information against the US Postal Service’s or the Canadian Postal Service’s database. The user will be prompted to try again if the information is incomplete or inaccurate. By doing so, you will be able to effectively move packages since you will only accept valid contact credentials.

Our checkpoints are as below:

  • PostGrid’s address checker can successfully verify both US and Canadian postal addresses in real-time or via batch upload
