How Sacramento came to have 2 area codes
The original Sacramento area code is 916, in service since 1947. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 279 (2018). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Sacramento now uses all 2 codes and every local call is dialed with ten digits.
