You can get a subscription to the US Postal Service to get CDs on a regular basis. Then you can write some code in your system to automatically upload the CD into your database when necessary.

>I'm looking to integrate into a VFP app some sort of methodology to validate zip codes entered by the user. The third-party app could charge you for this or not... doesn't matter. The most important part would be that it was available through the net or a .dll that would allow me to programmatically manipulate it. Furthermore, it would need to be a system that was dynamic and changed whenever the US Post Office changed or updated zip codes etc, to insure its current and accurate.
