Fake Addresses

Random Seattle, WA Address Generator

Seattle, WA test addresses generated by Fake Addresses are postal-format-valid and non-deliverable, built from 24 real ZIP codes in King County using the 206 area code. Every record's city, county, and ZIP code agree by construction, pulled from one geographic point, so the output passes format checks and fails delivery validation.

Frequently Asked Questions

Is it legal to use a random address generator for Seattle addresses?

Yes, for testing and development — using a random address generator becomes illegal only when the output is used to deceive a real system, such as a government form or a bank. See the full legal guide for the specific statute, 18 U.S.C. § 1342, and what it actually covers.

Will these Seattle addresses pass address validation?

They pass format and parser validation, because every Seattle record is postal-format-valid per USPS Publication 28. They deliberately fail Delivery Point Validation, because the street number is drawn from a range with no registered delivery point — both are intentional.

Could a generated Seattle address belong to a real person?

No. Every Seattle record is built for geographic coherence from one point on a real street, with a street number chosen outside any range assigned to a real delivery point, so the address does not describe a real resident. The full method is on the methodology page.

Do the ZIP code, county and city always agree for Seattle test data?

Yes. King County, the 206 area code, and the ZIP code shown are all derived from the same generated point inside a single ZIP Code Tabulation Area, checked on every build. See the validation harness for the exact method.

Can I generate Seattle addresses in bulk?

Yes — up to 10,000 rows at once, in CSV, JSON, NDJSON, or SQL, with no account required. Add ?seed= to get the same Seattle records back on every run, which is useful for a CI fixture.

What is the difference between a fake address and a random address generator?

A fake address is meant to deceive a real recipient. A random address generator like Fake Addresses produces postal-format-valid, non-deliverable Seattle test data with no real recipient and no deception intended — the full comparison is in this guide.
