Locations for Area Code - 865

Area code 865 serves the Knoxville metropolitan area in eastern Tennessee. Introduced in 1999 from a split with 423, the number was intentionally chosen to correspond with the letters “VOL” on a telephone keypad—a nod to the University of Tennessee Volunteers. The area includes Knoxville, Oak Ridge, and Maryville and plays a central role in Tennessee’s academic, scientific, and outdoor recreation sectors. Seven-digit dialing is still available for local calls. Area code 865 carries a strong sense of regional identity, especially in connection with college sports and East Tennessee pride.
