One of the nicest features to add to an address data entry screen is to automatically fill the city and state fields when a zip code is entered. In conjunction with the US Postal Service, FMS offers the Total Zip Code Database which gives you the entire list of valid zip codes and their corresponding city and state names. Both the primary and secondary city names are provided. Speed up data entry, eliminate typos, and clean up existing data with Total Zip Code Database. We also include the list of common city names the USPS doesn't like with their corresponding corrections. The database is provided on an annual subscription basis with an initial list and 11 monthly updates.
In addition to the information provided by the USPS, the Total Zip Code Database also includes geospatial coordinates (latitude and longitude) for each zip code. We also provide a list of countries and states to simplify lookups, and module code and sample form to add this to your applications. The data is provided in a Microsoft Access MDB and ASCII files.
