Find a ZIP Code and Check the Location

Use the table to look up postal-code entries and their canonical location labels. Search a code or a place name, then review the full label before using a result in your own list. For a separate place-name reference, see our US cities list by state.

Use ZIP Codes as Text, Not Numbers

Keep ZIP codes as text when importing them into a spreadsheet or CRM. Otherwise, a leading zero can disappear and change the code. Review the import preview and preserve the original value before sorting, matching or exporting records.

ZIP Codes Are Not City Boundaries

A ZIP code supports mail routing; it is not a substitute for a city’s legal boundary. The Census Bureau’s ZIP Code Tabulation Areas are statistical representations and do not include every valid USPS ZIP code. Avoid treating these different geographic systems as interchangeable.

This table is a reference rather than a current USPS address-validation service. Before sending mail or relying on a specific address, confirm it with the official USPS ZIP Code Lookup. Check the full address instead of assuming that a city name has only one ZIP code.
