On July 17, 2015 a new area code was approved for the North Western portion of the New York State including towns such as Syracuse and Utica. The new 680 area code will overlay existing NPA 315, therefore serving the exact same area. 10 digit dialing will become mandatory as a result.
See official NANPA announcement and map of the new overlay area (PDF document).
