How Roswell came to have 4 area codes
The original Roswell area code is 770, in service since 1995. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 678 (1998), 470 (2010) and 943 (2022). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Roswell now uses all 4 codes and every local call is dialed with ten digits.
