The service extends the provider's ZIP Code lookup service to allow specification of cities by their common names. For a submitted location, it returns other ZIP Codes and cities in the surrounding areas. The service can also provide distance between ZIP Codes and cities and provide mapping coordinates.
API methods support submission of a ZIP Code or city name to retrieve its location coordinates, nearby cities and locations, and adjacent ZIP Codes. Methods allow submission of a list places to determine the distance between them.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
