Find any 806- phone number in Texas
The 806 area code is a telephone area code in the North American Numbering Plan area that serves the northwest corner of the U.S. state of Texas. It is one of three area codes in the state that currently serves a large area, including Amarillo, Borger, and Canyon. The 806 code was established in October, 1957, and it was the second area code created for Texas.
The North American Numbering Plan (NANP) is the system in place for area codes and telephone numbers in the United States, Canada and some Caribbean nations. It divides the whole geographical area up into blocks of ten numbers, each of which is given an area code; 806 is part of the NANP, and thus refers to the numbering plan's definitive area code for that region of Texas. The NANP is overseen by the North American Numbering Plan Administration (NANPA), which coordinates and assigns all of the area codes throughout the region.
