Find any 870- phone number in Arkansas
Situated in the Southwestern region of the United States, Arkansas is home to one of the most well-known area codes in the country, the 870 area code. Contained within the 870 boundary is the entire state of Arkansas with the exception of a few select areas including the Little Rock and Fort Smith metropolitan areas, which are served by the 501 and 479 area codes respectively. 870 is part of the North American Numbering Plan (NANP) which provides a unified telephone numbering plan for the United States and its territories, Canada, and certain Caribbean nations.
Within this plan, 870 is a three-digit area code subtype known as an overlay. This system assigns distinct geographic regions to a geographical area by allocating a group of numbers to one specific region. An overlay extends an area code to areas that already have an area code, and provides additional numbers while preserving the original area code. Developed in the late 1990s, the 870 area code was the first overlay in Arkansas. Now dozens of new businesses and telecommunications companies now exist in the area, providing services primarily in the industrial and technology-focused regions of the state. Thanks to the NANP, telephone numbers are now easier to remember and exchanges can be more efficient.
