What Is My ZIP Code?

Use your device location to find the nearest US ZIP code. Your position is read by your browser, matched against our ZIP reference points, and never sent anywhere.

Tap the button and allow location access. Prefer not to? Look up a ZIP code instead.

Your browser asks permission and provides your coordinates; matching happens on your device against Codes.zone's committed ZIP reference points. The nearest centroid is an ESTIMATE of your ZIP code, not USPS address validation. Nothing is uploaded or stored.
