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 Iowa 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 Iowa addresses pass address validation?
They pass format and parser validation, because every Iowa 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 Iowa address belong to a real person?
No. Every Iowa 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 Iowa always agree with real geography?
Yes. Iowa has 829 usable ZIP codes across 99 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 Iowa 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 Iowa 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 Iowa 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.
