Amarillo, TX

ZIP code 79175 is a USPS PO Box–only code associated with Amarillo, Texas, rather than a defined residential or commercial district. Because it does not correspond to a mappable neighborhood, no public landmarks can reliably be said to lie within its boundaries. Amarillo’s best-known sites—including Cadillac Ranch, the Route 66 Historic District, and the American Quarter Horse Hall of Fame—are elsewhere in the city and should not be attributed to 79175.
