El Paso, Texas is served by a single area code, 915, and is unusual for Texas in that it observes Mountain Time rather than Central Time. Covering the city and El Paso County in the far western corner of the state, 915 has no overlay, so 7-digit dialing has historically worked, though 10-digit dialing is now the standard.

Area Codes in El Paso – Detailed Breakdown
915 – El Paso & Far West Texas
The 915 area code covers the city of El Paso and El Paso County in the far western tip of Texas, on the border with New Mexico and the Mexican city of Ciudad Juárez. It once covered a larger region before West Texas was split into the 432 code in 2003.
Neighborhoods & District Mapping
The 915 code covers every El Paso neighborhood, including Downtown, the historic Sunset Heights and Segundo Barrio, the affluent Westside near the University of Texas at El Paso, the East Side, the Northeast near Fort Bliss, and the Lower Valley along the Rio Grande. It also serves the surrounding El Paso County communities of Socorro, Horizon City, and San Elizario.
El Paso is the sixth-largest city in Texas and sits at the far western tip of the state, forming a single large binational metroplex with Ciudad Juárez across the border. Its economy is anchored by Fort Bliss – one of the largest U.S. Army installations – along with international trade and manufacturing, healthcare, and the University of Texas at El Paso. Because it lies west of the rest of Texas, El Paso keeps Mountain Time, one hour behind Dallas, Houston, and the rest of the state.
Local Dialing Rules & International Calls
Because 915 has no overlay, 7-digit local dialing has traditionally worked within El Paso, but dialing the full 10 digits is now the recommended standard and always works. To call a El Paso number from outside the United States, dial your country’s exit code, then +1 (the North American country code), then the 10-digit number (area code + seven-digit line number).
