Area codes 870 and 327

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.

[1] 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.

[4] 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[5] with a projected in-service date of February 20, 2024.

In long-term planning, the NANPA projects a boundary elimination overlay involving all three Arkansas numbering plan areas (479, 501 and 870/327), resulting in a statewide overlay; details for such have not been released.
