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.
Area codes 678 and 470 are North American Numbering Plan area codes assigned to metropolitan Atlanta, Georgia.They serve as overlays for the 404 and 770 area codes, which serve Atlanta itself and the suburbs respectively.rea codes 678 and 470 are North American Numbering Plan area codes assigned to metropolitan Atlanta, Georgia.
