what area code is 806

Area code 806 is located in northern Texas and covers Lubbock, Amarillo, and Plainview. It is the only area code that serves the area. The area code was created in 1957 in a flash-cut from numbering plan area (NPA) 915, the north-western corner of the state, but also incorporated a small portion of the region of area code 817 to the east. Prior to October 2021, area code 806 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.
