Area codes of Alabama

The U.S. state of Alabama is served by six area codes. When the North American Numbering Plan was first defined in 1947, Alabama was a single numbering plan area (NPA), with area code 205. This configuration existed until 1995 when area code 334 was added for the southeastern part of the state. In 1998, area code 256 was assigned for northern Alabama. It had an overlay area code 938 added in 2010, which required ten-digit dialing. The area code 251 in south Alabama was split area code from 334 in 2001. Area code 659 was installed in 2019, after having been proposed in 2001.

Area codes 608 and 353 are telephone area codes in the North American Numbering Plan for much of southwestern Wisconsin, including the state capital city Madison. Area code 608 was assigned in 1955 to a numbering plan area created from areas with area code 414 and area code 715, and was the third area code created in Wisconsin. Rapid growth of the area, specifically in Dane County, brought the area code close to exhaustion of central office prefixes, with NANPA projections in 2022 projecting the need for relief by late 2023. In September 2022, the Wisconsin Public Service Commission and North American Numbering Plan Administrator (NANPA) announced an overlay complex for the numbering plan area with new area code 353, with an in-service date of September 15, 2023. New central office code orders were accepted starting on July 11, 2023, but activatlon is contingent on complete exhaustion of central office codes for 608.
