Got a call from 865?

A 865 number was originally issued in Tennessee, but that does not prove the caller is there. 23% of 865 prefixes belong to VoIP and cable providers, whose numbers can be bought online and used from anywhere. Caller ID can also be spoofed, so treat urgent requests for money, codes or passwords from any area code with suspicion, and call back on a number you already know.
