The data behind the address.

Real locality records, with a clear boundary around what’s generated.

City, state & ZIP — together

Each location comes from one GeoNames US postal-code record. We keep the locality, state and ZIP together instead of choosing them separately.

GeoNames place names are locality labels, which may differ from municipal names. Records are provided as-is; this is not USPS address validation.

Streets are fictional

House numbers and Example, Sample, Demo or Test street names are generated locally. A matching locality does not make a street deliverable. Use these results for forms, prototypes and software testing.

Test profile fields

Names are fictional. US phones use the reserved 555-0100–0199 range; all other destinations use non-dialable X placeholders. Streets or lot, building and unit details are fictional.

Your collection stays with you

Generation runs in your browser using the bundled dataset. Saved addresses stay in local storage and are not uploaded. No account or third-party generation service is needed. Public-site visit analytics are described in Privacy and local data.
