Address Standardization API

The USPS offers an address standardization API for developers to use in their applications. This API makes it easier to compare addresses and find the most accurate one. This service is provided through the USPS website. To use this service, you must register and create an account with the USPS. This process may take a few days to complete. After registering and creating an account, the next step is to access the API.

The API can import XLSX, CSV, TXT, or geospatial data files. It also supports copying addresses from different applications. Then, it returns a result table with the original and formatted address as well as latitude & longitude coordinates. You can use this address standardization API to improve the accuracy of your data and increase your customers' satisfaction.

For example, the API will help you validate mailing lists. During the validation process, it will check for missing zip codes and other errors. It will also remove duplicate addresses. This will give you a cleaner and more efficient mailing list. It also helps you identify similar addresses and avoid misspending. With the address standardization API, you can be sure that your customers are getting the most accurate addresses possible.

Address standardization is an important service for businesses who send out direct mail. The USPS adds 4,221 new addresses each day, so it's essential to maintain accurate data.
