How York came to have 2 area codes
The original York area code is 717, 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: 223 (2017). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why York now uses all 2 codes and every local call is dialed with ten digits.
