Central New York will no longer be strictly 315. A second area code is being added in 2017.
The new area code for Central New York will be 680, according to the North American Numbering Plan Administrator.
The new 680 area code will be used alongside the 315 area code. People using the 315 area code will not be switched. The two area codes will serve the same calling area.
The only change current 315 area code customers will see is that they will now have to dial the full 1o-digit number in order to complete a call.
The 680 area code will service the 18 counties, including Cortland, Cayuga, Chenango, Madison, and Onondaga.
Most of Cortland County is in the 607 area code.
