Fake Addresses

Random Montana Address Generator

Montana test addresses generated by Fake Addresses are postal-format-valid and non-deliverable, built from 29 real ZIP codes across 2 counties and 1 area codes. 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.

Coordinates fall inside the ZIP boundary. Street numbers are drawn from ranges with no delivery point. The city name shown is the official place boundary for this point — the USPS last-line city source is not yet live for every ZIP.

Frequently Asked Questions

Is it legal to use a random address generator for Montana 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 Montana addresses pass address validation?

They pass format and parser validation, because every Montana 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 Montana address belong to a real person?

No. Every Montana 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 codes, counties and area codes across Montana always agree with real geography?

Yes. Montana has 29 usable ZIP codes across 2 counties in the dataset, and every generated record's county and area code are derived from the same point as its ZIP code, checked on every build. See the validation harness for the exact method.

Can I generate Montana 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 Montana 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 Montana test data with no real recipient and no deception intended — the full comparison is in this guide.
