Is 865 a country code?

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, shared across the North American Numbering Plan. So a full 865 number written for international dialing looks like +1 865 followed by the 7-digit local number.
