Dial-A-ZIP API

Correct bad addresses before you ship! The Dial-A-ZIP Application Programming Interface (API) is a small set of functions that may be called by any Windows application to provide address verification and correction.

ZIP-Stations are PC’s that can be a corporate or campus solution for those needing access to the ZIP+4 database for address verification of a large number of simultaneous users within their LAN, WAN or Intranet. Private access can also be provided to users via modem. IPX/SPX or TCP/IP protocols are available.
