Fake Addresses

Random Colorado Address Generator

Colorado test addresses generated by Fake Addresses are postal-format-valid and non-deliverable, built from 216 real ZIP codes across 11 counties and 6 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.

Frequently Asked Questions

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

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

No. Every Colorado 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 Colorado always agree with real geography?

Yes. Colorado has 216 usable ZIP codes across 11 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 Colorado 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 Colorado 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 Colorado test data with no real recipient and no deception intended — the full comparison is in this guide.

Prohibited uses of Fake Addresses test dataProhibited use

Do not use these addresses to deceive anyone. Do not use them on government forms, tax filings, financial or KYC applications, school-enrolment records, voter registration, insurance claims, shipping labels, or anywhere a truthful address is legally required. In the US, using a fictitious address to defraud through the mail is a federal crime under 18 U.S.C. § 1342.
