About

ZipCodeBright is a free site for US ZIP codes, area codes and address tools. Look up a ZIP, find an area code, check a ZIP+4, or format a mailing address — without signing up.

Address verification uses the Geocodio geocoding API with USPS ZIP+4 data. Reference pages are built from public Census, GeoNames and NANPA-derived data. See data sources.

ZipCodeBright is supported by ads so the tools can stay free. Questions? Email hello@zipcodebright.com.
