Zip Code Lookup

This tool allows you to look up the zip code(s) associated with most cities within the United States.

To begin, select the state.  CNAV will list all zip codes within that state in order of city name.  

Click on the zip code you are searching for to enter that zip code into the entry field.  If multiple zip codes are listed for a city and you are unsure of which one to use, always select the first code listed.
