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, GA utilizes an area code overlay in which area codes 404, 470 and 678 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.reas outside the I-285 perimeter highway which encircles Atlanta are assigned area codes 470, 678 and 770. Atlanta, GA is located in Fulton County and observes the Eastern Time Zone.
