Other ways to find your ZIP code

Check your mail

Any letter, bill or package delivered to you shows your ZIP code at the end of the last address line. If it has nine digits, such as 02108-1234, the first five are your ZIP code and the rest is the ZIP+4 extension.

Use your street address

Enter your full street address in the USPS ZIP Code Lookup to get the exact ZIP and ZIP+4 for your home. This is the answer to use on forms, bank records and shipping labels. Our guide to finding a ZIP code by address walks through it.

Look at your phone's map

Map apps show the full address, including the ZIP code, when you tap or drop a pin on a place. If you want to see ZIP codes in Google Maps specifically, read how to find a ZIP code on Google Maps.

Why your location ZIP can differ from your mailing ZIP

ZIP codes are delivery routes, not map shapes, and your device's position can be off by hundreds of meters indoors. Near a ZIP code's edge, the nearest reference point may belong to the neighbouring ZIP. PO Box holders also receive mail at the post office's ZIP code, which can differ from the home's ZIP. When the exact code matters, use your street address.

Outside the United States?

ZIP codes exist only in the U.S. and its territories. Elsewhere the local system has its own name and format, such as the postcode in the UK or the PIN code in India. See international postal codes or how to find your PIN code in India.
