Why are there no ZIP Codes in the Geographic Names Information System database?
The Geographic Names Information System (GNIS) contains named communities, both incorporated and unincorporated, but these communities do not necessarily correspond to ZIP Code areas. ZIP Codes are developed and maintained by the U.S. Postal Service solely for the purpose of delivering mail. It is not within the mission, purpose, or resources of the GNIS to maintain ZIP Code information. You can use ZIP Code™ Lookup to find the codes.
