Dialling from and to Atlanta
What this means when you pick up the phone.
Because more than one code covers this area, ten-digit dialling applies for local calls: area code plus number, every time. From abroad, dial +1 then the ten digits.
How Atlanta came to have several area codes
Why one city can carry several codes.
Area codes are assigned to geography, then exhausted as demand grows. Atlanta — population about 511k — is covered by codes 404, 678, 770, drawn from within 25 miles of the city centre. Because these 3 codes serve the same footprint, they are overlays: the number pool ran low and a new code was layered on top rather than splitting the city apart. All ten digits are required for every local call.
