Address Validation Standard API

The address validation standard API helps you identify possible address errors and returns a standardized address. Using this standardized address, you can perform a variety of address verification tasks. For example, you can check if an address matches the correct address for delivery purposes. When this validation is successful, you can return a standardized address and any changes made to it.

This validation API uses reference data to classify addresses. It also uses feedback from operational personnel to determine if an address is valid or invalid. Using this method, you can also validate multiple addresses with the same API. The address validation standard API offers four types of classification. The first classification is unknown, and all addresses remain in this classification until they meet the business rules for address validation. The second classification, mixed, applies to a location that has multiple tenants.

The address validation standard API is available to developers. USPS maintains an address database with 160 million addresses. There are also millions of non-postal addresses that are not included in the database. To account for this, developers can use address validation services like the USPS address validation API.
