In 1947, Georgia was a single numbering plan area (NPA) with area code 404. In 1954, 912 was assigned to its southern and central areas. The state operated with two area codes until May 3, 1992, when area code 706 was created for the two separate areas outside of the metro Atlanta area. Due to complaints from exurban residents who were to be put in 706, they were moved back into 404, which makes every new area code added to the metro area run out of numbers sooner. At this time, these areas were also fully included in what was already the world’s largest toll-free local calling zone (previously many were only able to call the adjacent telephone exchanges on the edge of metro Atlanta). Area code 770 was therefore assigned to Atlanta’s suburbs just three years later in August 1995, requiring ten-digit dialing between them, and with all mobile phones keeping 404. 678 was given to both the city and its suburbs in January 1998, becoming the first overlay area code in the state, and forcing mandatory ten-digit dialing for all calls.
