937 overlay codes and dialing
The 937 territory is covered by an overlay of 2 area codes: 326, 937. All of them serve the same geographic area, and the original code is 937. 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.

Is 937 a scam or spam risk?
937 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 937 number on your screen is no guarantee the caller is in Dayton, OH or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
