Correct and Standardize: Address Information System (AIS) Products

Before an address can be certified as deliverable (CASS-certified), it must first be standardized. Address correction software fixes spelling errors, corrects abbreviations, and standardizes capitalization so each address in your list complies with the USPS® official format. The USPS® definition of a standardized address is “one that is fully spelled out, abbreviated using the Postal Service standard abbreviations . . . or as shown in the current Postal Service ZIP+4 file." Please check here for the latest contact information.

Verify Your List

Once you’ve corrected and standardized your address list, you can then compare your data against the entire list of valid addresses in the Address Management System to determine validity. Address validity is based on many different factors, including address renumbering (via the USPS Locatable Address Conversion System) and address completeness. If an exact match is not found, an acceptable alternative is used (if available).
