History of Area Code 315

Area code 315 was established in 1947 as one of the original North American area codes. It was created to serve a large section of upstate New York outside the New York City, Albany, Buffalo, and Rochester calling areas. This makes 315 one of the earliest area codes in the United States.

Area code 680 was added as an overlay to 315 in 2017. The New York Public Service Commission approved the overlay because the supply of available 315 phone numbers was running low. Since the overlay began, new phone numbers in the region may use either 315 or 680, and 10-digit dialing applies to local calls.
