Area Code 915 History and Evolution
Area code 915 is one of the original 86 North American area codes, established in October 1947. Initially, it covered a much larger swath of West Texas, from El Paso to the Texas Panhandle and Fort Worth. As population grew and demand for phone numbers increased, the area covered by 915 was reduced through a series of splits:
Why Area Code Splits Occur: The North American Numbering Plan Administrator (NANPA) monitors number availability in each area code. When forecasts indicate an area code will exhaust its available phone numbers within 36 months, relief planning begins. Splits occur due to population growth and increased demand from mobile devices, pagers, and multiple phone lines per household or business.
