USPS Address Verification API

 

usps address verification api free

USPS address verification API is a service provided by the US Postal Service that will validate addresses for free. The service can be used to validate one address at a time, or it can be used to validate multiple addresses. The USPS address validation API will check for invalid addresses and give a thumbs-up or -down response to the user.

The USPS has a massive database of address data. However, they do not share this information freely. As a result, third-party companies provide address validation services that allow users to use USPS data in a less restricted way. Many third-party services also combine address data with supplemental information to produce an enhanced result. Most of these providers offer these augmented data to developers through APIs.

Address verification is an important part of ensuring that your mailings are delivered to the correct addresses. USPS address verification API uses data from different sources to ensure that all addresses are valid. This includes postal addresses, mobile numbers, and landlines. It's important to make sure that the addresses you're mailing to are correct, as an incorrect address will result in a poor package delivery experience.

The USPS address verification API is a free service that allows developers to validate postal information in a variety of ways. It also allows them to validate one address at a time, and confirm that addresses are accurate. Many businesses use these services to validate addresses and ensure the quality of their data.
