Area code 865

Area code 865 serves Tennessee, including Knoxville, Maryville and Oak Ridge (Eastern time). It has been in service since November 1, 1999.

Numbers starting with 865 drew 1,906 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 689 complaints to the FCC since November 2023. The number on your screen can be faked, so an 865 number proves nothing about where a call came from.

Phone companies holding 865 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 74% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
