History of Area Code 770
Area code 770 entered service on August 1, 1995, after a geographic split from area code 404. Area code 404 was Georgia’s original area code in 1947 and initially covered the entire state. By 1995, 404 primarily served Atlanta, while 770 covered surrounding suburban communities.
Area code 678 became an overlay for the Atlanta region in 1998. Area codes 470 and 943 followed as overlays in 2010 and 2022. These overlays added new telephone numbers without changing the geographic area associated with 770.
