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.
470 - Atlanta and its suburbs, overlay area code that covers same area as 404, 678 and 770; 478 - Macon, Forsyth, Fort Valley, Warner Robins, Dublin, Eastman and Milledgeville (central Georgia) 706 - Columbus (west-central Georgia); Rome, Dahlonega, Toccoa, Athens and Augusta (northwest, northeast, upper east-central Georgia) 678 - Atlanta and its suburbs, overlay area code that covers the same area as 404 and 770; 762 - same boundaries as 706; 770 - Atlanta's suburbs and exurbs; 912 - Savannah, Vidalia, Waycross, Brunswick, Douglas, and coastal Georgia.
