Amarillo, TX

ZIP code 79172 is a PO Box–only postal code associated with Amarillo, Texas, rather than a conventional neighborhood with defined street boundaries.

Amarillo attractions such as the Route 66 Historic District, the Amarillo Civic Center, and Hodgetown are elsewhere in the city and should not be attributed to 79172.
