Scammers spoof recognizable area codes so calls look local or familiar. A displayed 315 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 315 number from?
315 is assigned to Syracuse and surrounding areas of New York in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
