Address Lookup API

PostGrid has one of the best Address Lookup APIs in the world. After integrating PostGrid’s advanced Address Lookup API, you can simply submit the address to it and access all the details of that address. You can simply use PostGrid’s Address Autocomplete capability to lookup an address by directly entering the address and wait for the PostGrid system to return the complete postal address, including the ZIP+4 code.

PostGrid’s Address Lookup API provides you with every necessary detail of the address you are looking for, including primary number, street name, city, state, and ZIP Code. However, you do need to provide a valid primary number and a street address so that our system can close in on the potential addresses. The more details you provide on the address, the more precise the address lookup can even include the ZIP+4 code.

PostGrid is one of the most popular choices for address lookup APIs because it uses an advanced system that provides your business with accurate postal address data. PostGrid is certified by Coding Accuracy Support System or CASS, meaning that it is a reliable source of postal address data that the USPS themselves approves. PostGrid comes fully equipped with a ZIP+4 code lookup that allows for faster and more accurate postal delivery. Below we discuss the primary differentiators that set apart PostGrid from the rest of the crowd.

Superior Address Lookup With ZIP+4 Code

PostGrid comes equipped with advanced capabilities, including a full 9-digit ZIP code lookup. This means that every time you type in an address, PostGrid suggests the potential addresses and even provides you with a ZIP+4 code. The ZIP+4 code allows for quicker delivery and further reiterates the accuracy of the given address.

Advanced Address Verification API

PostGrid is a CASS-certified software, and every address lookup carries out by the PostGrid system involves a rigorous address verification. PostGrid’s Address Verification API accesses the official postal address database of the USPS and cross-checks the given addresses with it, and returns the full address based on this. This means that every address provided during an address lookup is a verified one and up to the standards of USPS, including the ZIP+4 code.

Enhanced User Experience

PostGrid allows you to constantly add to your CRM and our advanced address verification feature, ensuring your database’s accuracy. This means you don’t have to worry about manually entering each address into the system and then having them verified individually. You can customize your PostGrid API to automate the address clean-up directly from your CRM or simply download the address data to a CSV file and have them verified through PostGrid’s bulk tool in a matter of seconds.

Superior Data Quality & Improved Communication

With a CASS-certified address verification tool like PostGrid, you can expect a superior quality for the data you store. 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.

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. 

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.
