615 came first, in 1947
615 was Tennessee's original area code, assigned in 1947. The newest, 629, arrived in 2015. Each of the 7 codes below maps to its own part of the state, so the code you pick shows which region you serve.
Tennessee, by the numbers.
Tennessee's 1947 map included 615 (Middle Tennessee/Nashville), 901 (Memphis/west), and 423 (east).
Knoxville later split 865 off from 423, and western Tennessee gained 731, split from 901.
In 1997, 931 split off from 615 to cover a horseshoe-shaped swath of 28 counties surrounding Nashville.
Nashville's 2000s-2010s boom filled 615 again, so 629 was added in 2015 as an overlay rather than another split.
931 split from 615 to cover a horseshoe-shaped swath of 28 Middle Tennessee counties, one of the more unusually shaped numbering-plan areas in the country.
