Address Management System Application Program Interface

The Address Matching System Application Program Interface (AMS API) Developer's Kit is a tool used in the development of address-matching software. It is available on a CD-ROM commonly referred to as the AMS Commercial CD-ROM and 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

The test utility can be used to ensure that 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. This enables you to verify the accuracy of the ZIP + 4^® results returned from your product. The AMS software, including, but not limited to, .DLLs, shared objects and static objects all expire and cease functionality based on USPS CASS™ guidelines.

The USPS eLOT™, DPV™, and LACS^Link™ files can also be used in conjunction with the AMS API Developer's Kit.

An AMS API User Guide and order forms can be found on the RIBBS Web site at ribbs.usps.gov/files/amsapi.
