Fake Addresses

Random Illinois Address Generator

Illinois test addresses generated by Fake Addresses are postal-format-valid and non-deliverable, built from 1193 real ZIP codes across 101 counties and 17 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 Illinois 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 Illinois addresses pass address validation?

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

No. Every Illinois 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 Illinois always agree with real geography?

Yes. Illinois has 1193 usable ZIP codes across 101 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 Illinois 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 Illinois 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 Illinois 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.
