Atlanta, GA is currently assigned four area codes 404, 470, 678 and 770. Atlanta, GA utilizes an area code
overlay in which area codes 404, 470, 678 and 770 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary in Atlanta 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. The 770 area code overlay which is in use in Atlanta, GA today was put into service on August 1, 1995 and then area
code 678 was put into service on January 6, 1998 with area code 470 put into service on February 10, 2010.

Alpharetta, College Park, Douglasville, Duluth, Dunwoody, Forest Park, Gainesville, Griffin, Kennesaw, Lawrenceville, Mableton, Marietta, North Atlanta, Peachtree City, Redan, Roswell, Sandy Springs, Smyrna
and Tucker. All of these communities including Atlanta, Ga utilize the 470, 678, 770 area code overlay. In addition the larger communities of Atlanta, College Park, North Atlanta, Sandy Springs and Tucker
