Frequently asked questions
Are these Colorado ZIP codes real?
Yes — every one is a real ZIP Code Tabulation Area published for Colorado in the Fake Addresses dataset, sourced from official street and boundary reference data, never an invented five-digit number that merely looks plausible for the state.
Can a Colorado ZIP code repeat across two separate generations?
No — Fake Addresses draws each batch of 15 Colorado ZIP codes without replacement, so a single generated batch never repeats a code. A new generation reseeds independently from all 216 Colorado ZIP Code Tabulation Areas, so the same code can appear again in a later batch even though it never repeats within one.
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.
