How do I find my last U.S. residence Zip Code?

The United States Postal Service (USPS) has a useful website for looking up zip codes. To look up the zip code, you will need the street address (including house number), city/town, and state. Click here to access the USPS zip code lookup service.

Zip codes can change over time, so it is a good idea to verify your last U.S. residence zip code on the USPS website, as well as to obtain the "zip plus four" full zip code.
