507 overlay codes and dialing
The 507 territory is covered by an overlay of 2 area codes: 507, 924. All of them serve the same geographic area, and the original code is 507. 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 507 a scam or spam risk?
507 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 507 number on your screen is no guarantee the caller is in Rochester, MN or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
