Description

What is AMS API?

AMS API is software used to develop address matching software that provides access to USPS matching logic, which allows users to verify the accuracy of ZIP + 4 returns.

AMS API contains the following information:

  • API library(s) for each specific computer platform
  • Interface definition file (ZIP4.H)
  • Test utility (SAMPLE.EXE)
  • Test utility source code
  • Sample configuration data files
  • User documentation

The test utility can be used to ensure the Address Matching System and data files have been installed correctly and to provide access to USPS matching logic, which displays the standardized address returned by the matching engine. Additionally, the AMS software, including but not limited to .DLL files, shared objects, and static objects all expire and cease functionality based on the CASS™ guidelines.

The AMS API Product is updated monthly via Electronic Product Fulfillment.

Note: CASS certification is not a requirement for the AMS API Product. However, to receive automation discounts, users must obtain CASS certification.

Annual License Fee: Pricing varies depending on the products and platforms used.

Licensing information for AMS API can be found here.

What's next?

The AMS API License Agreement requires signature compliance and subscriptions are maintained on a calendar year basis. The RDI Product requires a direct license from the USPS.
