Area code 931

Area code 931 is the telephone area code in the North American Numbering Plan (NANP) serving a horseshoe-shaped region of twenty-eight counties in Middle Tennessee. Area code 931 initiated service on September 15, 1997 in an area code split of 615, which had previously served almost all of Middle Tennessee. The split reduced the numbering plan area to the inner ring of Nashville. Permissive dialing of 615 continued across Middle Tennessee until January 15, 1998.
