Frequently Asked Questions

They follow real US zip-code format (5 digits, first digit matches geographic region) but the specific codes are random. They may match real zip codes by coincidence — they're not pulled from a database, so don't use them as 'real' addresses.

Software testing (form validation, address parsing), database seed data, UI mockups, tutorial examples, learning code that handles addresses. Anywhere you need realistic-looking data without using real users' information.

US zip codes use the first digit to indicate region (0 = New England, 9 = West Coast, etc). We follow that convention so the codes look geographically plausible.

No. Don't use random zip codes to commit fraud, fake transactions, or evade verification. These are for development and testing only.
