Question 5

Is a call from area code 865 a scam?

Accepted Answer

A 865 number is geographically tied to Tennessee, but caller ID can be spoofed, so the displayed area code does not prove where a caller really is. If you did not expect the call, do not share personal information and consider looking the number up.

Question 6

Is 865 a country code?

Accepted Answer

No. 865 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1. So a full 865 number written for international dialing looks like +1 865 followed by the 7-digit local number.
