680 overlay codes and dialing
The 680 territory is covered by an overlay of 2 area codes: 315, 680. All of them serve the same geographic area, and the original code is 315. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.
History of the 680 area code
680 went into service on March 11, 2017 as an overlay of 315, relieving number exhaustion in the Syracuse area. Rather than splitting the region, the overlay lets existing customers keep their numbers while new lines draw from the added code. Learn more in our overlay guide.
Is 680 a scam or spam risk?
680 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 680 number on your screen is no guarantee the caller is in Syracuse, NY or trustworthy.
