Random ZIP code generatorRandom ZIP code generator.
Generate random U.S. ZIP codes that actually exist: pick a quantity and, if you like, a state. Each result shows the place, state and county and links to the ZIP's page, drawn from 41,706 postal reference records.
Generate random ZIP codes
Choose how many codes you want and, optionally, a state. Every result is a real ZIP code from the reference dataset. A generated ZIP is not a generated address and does not validate any account or form.
Why use real ZIP codes for test data?
Made-up five-digit numbers can fail validation in payment forms, shipping calculators and address checks. Sampling from real reference records gives you codes that pass basic format and existence checks, while the linked place names help you spot mismatched test data.
Need every ZIP code instead?
For a complete list rather than a sample, each page in the state directory offers the state's ZIP codes as a CSV download.
