Amarillo, TX

ZIP code 79166 is a special-use postal code associated with Amarillo, Texas, rather than a conventional neighborhood with clearly defined street boundaries. Because it is used for postal delivery, major public landmarks cannot reliably be identified as lying within the ZIP itself. Amarillo attractions such as Cadillac Ranch, the Route 66 Historic District, and the American Quarter Horse Hall of Fame are city landmarks, but are not necessarily within 79166.
