Area Code 315 History:
Area code 315 was put into service. In 1954 area code 315 was split to form a portion of area code 607.
On March 11, 2017 area code 680 was put into service as an overlay of area code 315. Effective 2/11/2017 ten digit dialing (area code + seven digit number) became necessary in the 315/680 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
