The U.S. Postal Service publishes a CD-ROM of national addresses called the AMS (Address Matching Service) CD-ROM. New CD-ROM's are issued on the 15th of each even numbered month for a total of 6 CD-ROM's per year.

Most of our programs include the option to access a local AMS CD-ROM for the Dial-A-ZIP® lookup. In cases where the volume of addresses being processed is high, we recommend purchase of an AMS CD-ROM.

To Purchase the AMS CD-ROM
