As PostGrid’s API directly accesses the official postal address database of the USPS, there is little to no chance of bad data entering your system. Furthermore, PostGrid enables you to check the validity of the data provided by your customer at the point of onboarding itself, meaning that you get to keep a clean database with superior data quality.

Improved Communication

For businesses that make use of postal mails to communicate with their customers, PostGrid can greatly improve their communication. PostGrid’s advanced address verification system greatly impacts even the marketing efforts made through direct mails because it greatly boosts your campaign’s reach. This is possible because of the high deliverability rate offered by PostGrid.

Types of Address Lookup API

Businesses use the address lookup API in many ways, including-

Predictive Search

Type-ahead validation helps users pick their correct address from a suggestions list.

It is predictive because the API starts showing the suggestions as users type in their mailing addresses. This step reduces the number of keystrokes and saves time.

Predictive search is best for companies that sell their products online and prompt customers to place orders. Their customers can checkout faster without typing their complete delivery address, improving the overall buying experience.

Some refer to type-ahead address lookup as single-field verification. Websites using this address lookup API type only have one line for the delivery address.

Users must start entering their apartment number and street name, followed by the city, state, and ZIP code. But many customers type their city names first.

PostGrid’s address lookup API ensures you only record fully-formatted addresses—error-free and deliverable!

Bulk Address Lookup

It is also known as post-entry address validation. You can complete the bulk address lookup process through PostGrid’s address verification API or software.

The API integrations let you fetch customer records from your CRM or website for validation.

Unlike type-ahead address lookup, which is real-time, bulk lookup can happen whenever required.

Post-entry address lookup is ideal for conducting direct mail campaigns. For example, imagine having thousands of old customer entries in your database. You can use bulk verification to check which records are valid or outdated.

Other applications of the bulk address lookup API include

  • Data management: Put your databases to good use and maintain high quality with PostGrid’s address verification services.
  • Business decision-making: Conduct data mapping and market research to make crucial business decisions—all with the help of an address lookup API.
  • Location-based marketing: Companies can launch EDDM campaigns by verifying existing mailing lists and determining the most customer-dense areas.
  • Mailing list segmentation: Categorize your mailing lists according to locations and demographics for better usage.

Drop-Down Address Lookup

The drop-down validation layout makes it quick and easy for users to understand and fill out the checkout forms. In this case, all address elements have separate columns, including-

  • Apartment or room number
  • Company name
  • Street name
  • City
  • Street
  • ZIP code

Users can manually type the first three fields. The city and street columns have a drop-down menu allowing them to click on the button and select their respective city, state, or territory.

Most eCommerce websites automatically fill out the ZIP code once the user enters the other details.

For example, if you use PostGrid’s address lookup API, it shows you the complete address. Hence, your customers can stop after typing the company and street name and let PostGrid fill in the rest. All users have to do is type the word one to four letters for the system to make guesses and show you the suggestions.

Partial Address Lookup

PostGrid offers the address autocomplete features to add missing details to partially-completed addresses. It also uses fuzzy logic to identify-

  • Typos
  • Misspellings
  • Extra spacing
  • Capitalization issues
  • Missing ZIP codes
  • Incorrect street directions
  • Invalid street abbreviations

Partial address lookup also refers to cross-verifying only some address parts. It is apt for scenarios wherein you already know the other elements are correct. For example, checking the street addresses and secondary units is adequate to target prospects in a specific city. You already know the city and state! And finding out the ZIP code is simple by using the street names.

PostGrid’s address lookup API helps convert your customers’ inputs into accurate delivery addresses. You may use the returned results for mailing, marketing, decision-making, and other purposes.

What Are the Different Steps of an Address Lookup API?

Address lookup consists of many steps comprising.

Customer Record Matching

PostGrid matches your customers’ mailing addresses with the USPS authoritative database. Since we are CASS-certified, we can enable you to access the Post Office data to check whether your mailing lists are valid.

USPS has a database of millions of US addresses and ZIP codes. Cross-confirming your lists using our solutions lets you ensure accurate and timely deliveries.

If PostGrid’s address lookup API does not find a match for an address, it marks it invalid.

Also, you can get the geocoding data, accuracy score, and Delivery Point Validation (DPV) codes with the results.

NCOA Checking

The National Change of Address system checks whether customers or prospects have moved to a different address in the past five years. If yes, it provides the new location, helping you update your records and continue mailing campaigns.

PostGrid processes your mailing lists against the NCOA data files to ensure the final results are ready-to-mail.

It lets you feed in your customers’ information and returns an error-free mailing list in seconds. Our scalable address lookup API can validate 160k addresses simultaneously, speeding up the process!

Integrating our API into your website guarantees customers can checkout using a valid address, regardless of volume or uptime.

PostGrid has an excellent API uptime and can handle bulk address lookup requests without slowdowns or glitches.

Address Standardization

Formatting addresses according to the USPS guidelines is crucial if you send your mailers through postal services.

Below is the USPS-prescribed address format:

Recipient’s name

Company’s name

Apartment number and street address

City, state abbreviation, and ZIP code

The USPS mail-sorting machines read the delivery addresses on your letters and parcels from the bottom up. Thus, mentioning the ZIP code on the last line is critical, enabling the equipment to categorize your mail and allot delivery routes.

International Address Identification and Verification

PostGrid’s address lookup API can identify global addresses of more than 245 countries and territories. It allows you to validate your mailing lists, irrespective of the locations you serve.

Our international address verification solutions can reformat your international addresses based on the destination country. We also transliterate your mailing lists to guarantee deliverability in any place worldwide.

Businesses can use our address lookup API to expand their business beyond borders. Our advanced verification features can transform customer address details into high-quality and profitable databases.

Also, we provide geocoding and reverse geocoding to let you fully benefit from our address lookup solutions.

What Type of Businesses Need Address Lookup API

eCommerce Businesses Third-Party Logistics Companies
PostGrid’s Address lookup validation is a perfect match for eCommerce businesses. It enables eCommerce businesses to get an accurate address of their customers. Plus, it also has the potential to enhance the user’s shopping experience by offering a convenient way of placing orders. PostGrid’s address lookup suggests the customer’s address even as he/she is typing it in, allowing them to autofill the address with ease.

Third-Party Logistics Companies
Third-party logistics companies, especially those in contract with online brands and other product-selling businesses, can make the most out of address verification and lookup tools like PostGrid. We enable third-party logistics to make accurate deliveries with minimal or negligible return rates. By doing so we ensure that they serve their customers better and help them establish credibility with their partners.

Short-Term Rental Home Service Sites
Addresses are perhaps the most important information or data in possession of short-term rental home service sites. With PostGrid, their customers can easily look up properties on their site, and the admin can also verify the addresses before it is listed on their website. PostGrid helps short-term rental home services provide reliable data on their properties and thereby gain their customers’ trust.

Credit Check Services Zero-Code Integration
The credit check that banks or other financial institutions often carry out requires an address verification service to ensure the data’s accuracy. The Address Lookup API of PostGrid is also aimed at address verification and can prove to be extremely useful for such cases. This also helps such services to keep their spending in check and avoid unnecessary wastage.

What is a Reverse Lookup or Reverse Geocoding API?

A reverse address lookup API is also famous for reverse geocoding. They are the exact opposite of geocoding. You need to enter the coordinates of a particular location to find the corresponding address. It could be helpful when you want to identify a customer's address using their latitude and longitude data. 

Suppose you enter the coordinates “35.2519N – 120.6836W”; it will give you a return address “137 Creekside Lane, San Luis Obispo, California”. PostGrid can help you fetch addresses by entering geographic coordinates. 

What is Address Autocomplete?

When you enter a query on Google search, it automatically gives you suggestions to complete your search. An address autocomplete API works similarly by providing recommendations for the part of your users' address. 

It is a brilliant method of avoiding input errors and providing maximum convenience to the users. Autocomplete may look similar to geocoding. Yet, both have entirely different goals. An autocomplete API expects the user to select the appropriate suggestion. At the same time, geocoding API requires complete address information as input data to provide accurate results.

Best Practices You Need to Ensure High-Quality Address Verification 

Address verification tools might provide automatic validation and standardization capabilities. Yet, professionals must keep their address data clean to avoid failed deliveries, lost shipments, or frustrated customers. 

It is not a one-time process; you must continuously update and maintain your address data. You should follow the best practices during the address verification process. 

Gather Comprehensive Address Information 

An address verification tool can recognize even the most minor inputs. Yet, we recommend gathering all necessary information. 

Try to include the street address, city, state, and ZIP code for each entry to get accurate results. The more information you have, the more precise the verification process will be.

Validate the Addresses

Professionals must ensure that an address is accurate and deliverable before using it. An address verification tool will compare the address against the official address database of the country. 

It will also try to fix mistakes, such as typographical errors or incomplete information. You will get a valid and deliverable address by running a validation check.

Standardize According to the Local Postal Standards 

Many tools will help you standardize the address formats. Yet, you must normalize the structure to make lookup and verification faster and easier. 

Pro Tip: try using abbreviations instead of using complete forms like “Avenue,” “Street,” and “Boulevard.” It will also help the postal workers while sorting and mailing your item. 

Update Your Database Regularly 

Companies and professionals must update their address database regularly. People could be moving now and then. Negligence can lead to lost packages or failed deliveries. They must rely on a reliable data provider to get the latest information about the customers. 

Use Geocoding Tools 

These days, address data relies on more than textual information. It also requires accurate geographic coordinates to support navigation and other processes. A Geocoding API can convert an address into latitude and longitude. 

Professionals visualize the addresses on a map to spot any inaccuracies. It improves quality, reduces errors, and builds customer experience. 

Experts Divide Address Lookup Tools into Four Categories 

Almost any business can benefit from address verification solutions. It can streamline operations, reduce delays, increase customer satisfaction, and more. 

Address data is helpful for various locations. One can use this data for geotargeting and marketing. We can divide address lookup APIs into four categories for more straightforward classification;  

Searching Locations by Address 

These APIs allow users to enter an address to find the corresponding location. This process of finding a place is also known as Geocoding. A professional must have the geographical address of the customer to locate on a map. 

It can help plan a delivery route or estimate the distance between locations. 

Finding Addresses by Coordinates 

Professionals can use coordinates to find the corresponding postal address. It is precisely the opposite of Geocoding. This process could be beneficial when a firm wants to identify a customer’s location by their geographical coordinates. 

Many professionals use it for fraud detection and identity verification. PostGrid can help you get addresses to match geographical coordinates. We can provide the most accurate postal address to locate your customers. 

Address Standardization 

People can find multiple methods of writing the same address. However, only a few will be the standard format according to the regional postal regulations. Things are more complex when you consider the different formats of international addresses. 

An address standardization solution ensures that they register addresses correctly. They can easily convert addresses into the correct format for postal services. It helps in reducing invalid or incomplete information in the address databases.  

Address Verification 

These solutions help professionals and firms check the validity of addresses. It can save their valuable time and resources that an incorrect address can hamper. 

For example, incorrect deliveries can lead to customer frustrations and lost revenue. Verifying addresses also helps companies to avoid fraud or errors in shipping addresses. 

How Address Lookup Tools Can Ensure Efficient Logistics and Delivery Operations?

Any delivery or logistic company gives vast importance to address verification and lookup solutions. Incorrect, incomplete, or non-standardized addresses are the main reason behind delays or failed deliveries. 

A single problem is enough to compromise your processes and pace of business. 

They must ensure timely and efficient operations to meet consumer expectations and optimize business processes. A minute mistake in address data can impact everything, from the initial routine planning to final delivery. 

Here is how address lookup tools can help these companies;

Timely Deliveries 

Accurate address data administers on-time deliveries. It is a crucial aspect of building a healthy brand image and meeting consumer expectations. Otherwise, they would look for your competitors. 

Delivery drivers with accurate addresses can reach the recipients with clarity and speed. It would ensure seamless deliveries and better customer satisfaction. 

Avoiding Financial Losses and Building Customer Trust 

Lousy address data leaves a significant impact on a business and its processes. Failed deliveries can add additional operating costs. 

Moreover, a company could lose customer trust and credibility over such issues. An accurate address verification solution can help in facing these problems. 

Reducing Fuel Costs 

Incorrect or incomplete addresses can compel drivers to take longer routes to find the right recipient. It only consumes more fuel and time, reducing efficiency as well. Address verification and lookup tools can help drivers take the most efficient delivery routes. 

Improving Operational Productivity

Delivery and logistics companies may need to handle large volumes of deliveries. Accurate addresses are always helpful in increasing the productivity of a company. They can manage more locations in a day than ever before. 

These firms can easily make more deliveries in less time without much effort. It can improve their customer service and cost savings. Ultimately, these factors contribute to better business growth. 

Reduction of Delayed Shipments

These companies can lose a significant customer base with delayed shipments. Address verification is necessary to reduce the risk of delays and dispatch packages on time. 

No one wants to spend additional time making meaningless deliveries. It would also reduce the number of customers going to competitors. Many companies lose revenue to their competition because of delayed shipments. 

Decreasing Wastage of Resources 

An incorrect or incomplete address can also lead to failed delivery attempts. A logistics and delivery company must provide more resources to make these attempts. 

It wastes valuable resources, such as fuel, labor, and vehicles. This wastage could pile up into a loss of revenue and business opportunities. 

Accurate address verification solutions can decrease the chances of failed deliveries. Companies don’t need to take the headache of resource wastage and reduced efficiency. 

Efficient Planning of Routes 

These companies need to prioritize route planning to save time and resources. Accurate address verification is necessary to guarantee all the delivery addresses are correct. 

Then, they can easily optimize their routes by minimizing detours or backtracking. They won’t waste time or resources on a particularly tricky path. 

An efficient route is necessary to save fuel and let the company handle higher volumes of deliveries in a day. They save more money and also reduce their environmental impact. 

Why Address Verification Matters for Businesses? 

Every business wants to minimize the room for errors while dealing with customers or customer representatives. 

You also must manage address data with care to evaluate its genuineness. An address verification or lookup API can help businesses to check their addresses against an official database. For example, the USPS and Canada Post databases.

It helps them determine the validity of each address and increases the possibility of having the correct customer address. Cross-checking with official databases also streamlines the mailing process 

There’s a reason why professionals prefer investing in address validation solutions to get peace of mind. Their customers also get a more seamless experience during the checkout window. We cannot undermine the importance of accurate data in the age of complex addresses and cyber fraud. 

How to Select a Suitable Address Lookup API?

Firms and professionals often need help with choosing an address verification solution. It is more challenging since there are many options available in the market. The right fit is necessary to guarantee data quality and flexibility. 

An irrelevant solution can cause trouble instead of providing any assistance. Firms should only consider a tool when they have a requirement. 

Experts consider various factors while deciding on an address verification solution. The cost and technical expertise are also necessary for correct implementation and maintenance. A company with budget constraints can have vast issues using the software in the long run. 

Accuracy of Address Data

Professionals and firms need high accuracy with their address verification solutions. Inaccurate tools can cause confusion and mismanagement of location data. 

Users must be able to verify, validate, and standardize addresses in real time. The data collection process will be more accurate and reliable with this approach. There’s no point in address verification if the results are not accurate. 

Your choice of API should verify addresses against multiple data sources to provide the maximum level of accuracy. PostGrid compares addresses against the USPS official address database and other reputable sources. 

Scalability of the API 

An organization’s address verification needs to evolve. The solution must scale up or down according to the requirements. Firms and professionals should look for solutions capable of managing large volumes of data in real time. 

Cost of the Solution 

Budget is often a primary constraint for companies while selecting an address lookup or verification solution. The pricing might depend on the accuracy level or functionalities of the software. 

Try to look for flexible solutions that give value for money and flexible payment plans. 

It would help companies to save a lot of revenue. They can also scale the API according to their convenience. 

Ease of Use to Find Addresses
