Area Code 915

Where Is Area Code 915 Located?

Area code 915 primarily serves the far western corner of Texas, centered on the city of El Paso. It covers El Paso County along with parts of Hudspeth and Culberson counties. The region is geographically separated from the rest of Texas by long stretches of desert and lies right along the U.S.–Mexico border.

Some of the main cities and towns covered under area code 915 include:

  • El Paso
  • Socorro
  • Horizon City
  • San Elizario
  • Anthony
  • Canutillo
  • Fabens
  • Van Horn

The area code also serves the Fort Bliss military base and several smaller communities, making it a widely used code across far West Texas.

History of Area Code 915

Area code 915 was created in 1947 as one of the original 86 area codes in the North American Numbering Plan. At that time, it covered a vast portion of western Texas, stretching from El Paso all the way to the Fort Worth region and the Texas Panhandle.

Over the years, the original territory was divided several times. In 1954, the eastern portion was split off to form area code 817, and in 1957, the Panhandle region became area code 806. The most recent change came in 2003, when area code 915 was split again to create area codes 325 (covering Abilene and San Angelo) and 432 (covering the Midland–Odessa region). Today, 915 serves only the El Paso area and its surrounding communities.

Time Zone of Area Code 915

Unlike most of Texas, area code 915 follows the Mountain Time Zone (MT), which is one hour behind Central Time. This includes:

  • Mountain Standard Time (MST)
  • Mountain Daylight Time (MDT) during daylight saving

This makes 915 the only area code in Texas that operates predominantly on Mountain Time, which is important for businesses and individuals communicating with people in other parts of the state.
