Area codes 870 and 327
area code for eastern and southern Arkansas, United States

Area codes 870 and 327 are telephone area codes in the North American Numbering Plan (NANP) for southern, eastern, and most of northern Arkansas. 870 was created on April 14, 1997, in a split from area code 501, Arkansas's original area code of 1947, and 327 was added as part of an overlay complex in 2024.
History
Area code 870 was first created in an area code split of 501, and comprises most of the state outside the Little Rock, Fort Smith, and Fayetteville/Springdale/Rogers areas. Major cities in the area include Jonesboro, Mountain Home, Pine Bluff, Texarkana, El Dorado, and West Memphis.
In 2009, the Arkansas Public Service Commission projected that the supply of unassigned telephone numbers for 870 would run out in 2013, prompting a December 2009 approval of an all-service overlay complex in this portion of the state. Area code 327 was assigned for this purpose in January 2010. The release of little-used central office codes and the nationwide introduction of number pooling delayed the exhaustion of the numbering pool and the relief action was indefinitely suspended in June 2012.
Per a 2021 NPA exhaust study by the North American Numbering Plan Administrator (NANPA), area code 870 is projected to exhaust in the first quarter of 2025. Area code 327, per the Arkansas Public Service Commission, has been selected and is in the network preparation phase for relief as an all-service overlay code for the 870 numbering plan area with a projected in-service date of February 20, 2024. Mandatory ten-digit dialing of area code 870 started on January 19, 2024.
