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. The 470 area code is a fairly new addition to the city of Atlanta. Implemented as recently as 2010, it was created as an overlay to the 678 area code. Accordingly, Atlanta residents are required to dial ten digit numbers even when making local calls.he excellent temperatures in the Atlanta, GA area code make it ideal for sports. Many professional sports teams are based in the 470 area code including teams for the MLB, NFL, and WUSA. The Atlanta Braves are part of MLB and have consistently performed well, including a win at the World Series in the 1990s.
