About our ZIP code data
Our tools use ZIP code records based on U.S. Postal Service data, plus U.S. Census Bureau data for ZIP code boundaries and demographics. Distances are measured in a straight line between ZIP code center points. ZIP codes do change from time to time, so for important mail, always confirm an address with the official USPS ZIP Code Lookup.
