The County - ZIP Code Database lists all ZIP Codes and counties in the United States and its territories to which the United States Postal Service (USPS) delivers mail. What makes this database unique is that it lists every county-ZIP Code combination which exists in the real world. Other databases list only a single county for each ZIP Code.
In the real world, ZIP Code boundaries often cross county boundaries. This means that a particular ZIP Code may lie in several counties. In fact more than 20 percent of all ZIP Codes lie in more than one county. For example, ZIP Code 38583 covers portions of five different counties! Clearly, you cannot assume that a particular ZIP Code lies completely within the one county listed by other ZIP Code databases.
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.
The database contains approximately 55,000 records.
We update every record in County - ZIP Code Database monthly, so you always receive the latest and most up-to-date data. You can't get more accurate and timely ZIP Code data from any other source! We license our ZIP Code data directly from the United States Postal Service.
