Area Code 770 History

Area code 770 was put into service. Area code 770 was created from a split of area code 404. In 1998 area code 770 was overlaid with area code 678 and in 2010 area code 470 was put into service as an overlay of area code 770. This resulted in an area code overlay complex of 404, 470, 678 and 770. Ten digit dialing is mandatory in area code 770.
