Area code 915 serves far western Texas, including El Paso, Fort Bliss, and surrounding areas along the U.S.–Mexico border. One of the original 1947 codes, 915 once covered a vast area before being reduced to El Paso and vicinity. The region is heavily influenced by Mexican culture and international commerce, with El Paso being a key military, medical, and trade hub. Seven-digit dialing is still permitted for local calls. Area code 915 is a cultural and economic bridge between the U.S. and Mexico, reflecting El Paso’s unique identity in Texas and the Southwest.
