County Zip Code

The County-ZIP Code Database provides a comprehensive list of ZIP Codes and their corresponding counties across the United States and its territories, as served by the USPS. Unlike other databases that link a single county to each ZIP Code, this unique database accounts for ZIP Codes that span multiple counties due to real-world boundary overlaps. Using the County-ZIP Code Database, you can find every ZIP Code which lies partially or completely within a given county. Or you can find all counties which contain some portion of a particular ZIP Code. You also can find the preferred city name associated with any ZIP Code, and the county FIPS code associated with any county. Compiled by Melissa from diverse sources, including USPS, the database strives for accuracy across its approximately 55,000 records.
