Newnan, GA is currently assigned three area codes 470, 678 and 770. Newnan, GA utilizes an area code overlay in
which area codes 470, 678 and 770 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary in Newnan 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 area code overlay which is in use in Newnan, GA today was put into service on February 10, 2010 when area code 470 was
implemented. Area code 470 and 678 also overlays area code 404 in the Atlanta area.
