Fake Addresses

Random Ontario, CA Address Generator

Ontario, CA test addresses generated by Fake Addresses are postal-format-valid and non-deliverable, built from 3 real ZIP codes in San Bernardino County using the 209 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 Ontario 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 Ontario addresses pass address validation?

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

No. Every Ontario 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 Ontario test data?

Yes. San Bernardino County, the 209 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 Ontario 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 Ontario 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 Ontario test data with no real recipient and no deception intended — the full comparison is in this guide.
