About ZipCodeMap.org

Free, fast ZIP code tools: a map of all 41,154 U.S. ZIP codes, radius search, lookups by address, city, county and metro area, and the numbers behind each ZIP code.

We built ZipCodeMap.org because most ZIP code sites are slow, cluttered or hide exports behind paywalls. Every tool here is free, works on a phone, and lets you copy or download your results.

All data comes from public sources: the U.S. Census Bureau, the Office of Management and Budget, GeoNames and Zillow. See the methodology for details and caveats.

ZipCodeMap.org is a sister site of RealEstateCalculator.org. It is not affiliated with the U.S. Postal Service.
