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.
Atlanta and Decatur are Georgia's only county seats inside the Perimeter interstate (I-285) that encircles the metro area. Atlanta is an international city with corporate headquarters, world class convention facilities and a fast pace, while Decatur has retained a small city feel and a slightly slower pace.
