Area code 334

The numbering plan area (NPA) comprises the Montgomery, Auburn-Opelika, and Dothan metropolitan areas, as well as Phenix City and the Alabama side of the Columbus, Georgia metro area. The original 334 territory included the southern half of Alabama. The southwestern part of the numbering plan area was split off with Area code 251 in 2001, including Mobile.

Area code 334 was the first interchangeable NPA code, not having the middle digit of 0 or 1, officially preceding Washington area code 360 by one minute.

NANPA projections in 2023 suggested that an additional area code will be needed in southeastern Alabama by early 2026, as 334 is nearing exhaustion. Area code 483, which the Alabama Public Service Commission approved, has been assigned for relief through an all-service overlay complex. The activation date has not yet been announced, but ten-digit dialing will be required before such occurs.
