atlanta georgia area code
Georgia was first supplied with only one area code, 404, in 1947. In 1954, 912 was given to its southern and central areas. The state would operate with two area codes until May 3, 1992, when 706 was created for the two separate areas outside of the metro Atlanta area.lip-flopping on its position on assigning new area codes, the Georgia Public Service Commission dictated that a double split of 912 would occur after that, with 229 and 478 being applied to southwest Georgia and central Georgia in August 2000.
