What started as a simple telecommunications assignment has evolved into one of Georgia’s most recognizable area codes.

The 678 area code emerged as Atlanta’s third area code, marking a significant expansion in Georgia’s telecommunications infrastructure. This overlay code operates alongside 404 and 770 to serve the growing metropolitan Atlanta region.
History and Origins
The Georgia Public Service Commission introduced area code 678 on January 1, 1998, responding to the rapid depletion of available phone numbers in the existing 404 and 770 codes.

The implementation of 678 made Atlanta one of the first U.S. metropolitan areas to require 10-digit dialing for all local calls, reflecting the region’s exponential population growth in the 1990s.
Geographic Coverage
Area code 678 spans across 14 counties in the metro Atlanta region, including Fulton, DeKalb, Gwinnett, Cobb, and Clayton counties. The code services major business districts in Alpharetta, Sandy Springs, Marietta, and downtown Atlanta. Its coverage extends from Roswell in the north to Peachtree City in the south, encompassing both urban centers and rapidly developing suburban communities.
