ZIP Code API - Database Interface

This API provides for XML or JSON responses at the ZIP code resolution level. The simpliest way to view results is to click on one of the sample links below or paste the link into any browser's URL box. Just pass in an address, or portion of an address, and leave the username as "sample" and password as "password". The response results will be returned in the appropriate format determined by the URL you have used.

This sample query string will allow for unlimited testing with ZIP codes between 90001 and 90999. If you would like to perform testing outside of that range, please call 866-492-8494 or e-mail us to request a free limited-time account. For subscription information, check out our Database Interface pricing.
