This once-vast numbering plan area (NPA) was reconfigured in 1954, in 1957, and in 2003 to accommodate the developing infrastructure for long-distance toll telecommunication, population growth, and finally proliferation of mobile devices, such as pagers and cell phones. In 1954, nearly the entire eastern portion ([Lubbock](/source/Lubbock) and the [South Plains](/source/South_Plains)) was combined with Fort Worth and the western portion of [area code 214](/source/Area_code_214) in a flash cut as [area code 817](/source/Area_code_817). In 1957, most of the northwestern portion (the [Texas Panhandle](/source/Texas_Panhandle)) was merged with the western portion of 817 to form [area code 806](/source/Area_code_806). In 2003, the numbering plan area was reduced in a three-way split in which the western portion retained area code 915, the eastern portion ([Abilene](/source/Abilene%2C_Texas), [San Angelo](/source/San_Angelo%2C_Texas), etc.) received new [area code 325](/source/Area_code_325), and the central portion (the [Permian Basin](/source/Permian_Basin_(North_America))) was identified by [area code 432](/source/Area_code_432). ### Ten-digit dialing Prior to October 2021, area code 915 had telephone numbers assigned for the [central office code](/source/Central_office_code) 988. In 2020, *988* was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/Seven-digit_dialing). This area code was therefore transition to [ten-digit dialing](/source/Ten-digit_dialing) by October 24, 2021.[1] ## Service area Counties served by area code 915 are [Culberson](/source/Culberson_County%2C_Texas), [El Paso](/source/El_Paso_County%2C_Texas), and [Hudspeth](/source/Hudspeth_County%2C_Texas).
