How the area codes came to Tennessee

901 covered Tennessee on its own for 7 years, until 615 began in 1954.

1. 1947: 901 was one of the original 1947 area codes, serving Arlington, Collierville and Covington.
2. 1954: 615 launched as a new area code, serving Adams Cedar Hill, Ashland City and Bethpage.
3. 1995: 423 was created by splitting from 615, serving Apison, Athens and Baileyton.
4. 1997: 931 was created by splitting from 615, serving Ardmore, Baxter and Beech Grove (coffee).
5. 1999: 865 was created by splitting from 423, serving Bean Station, Bent Creek and Chestnut Hill.
6. 2001: 731 was created by splitting from 901, serving Adamsville, Alamo and Atwood.
7. 2015: 629 joined 615 as an overlay, covering the same area.
8. 2025: 729 joined 423 as an overlay, covering the same area.

Telephone dialling in Tennessee

For 901 and 931, a local call is dialled with 7 digits; long-distance calls need 1 + the 10-digit number.

For 615, 423, 865, 731, 629 and 729, a local call needs 10-digit dialling; long-distance calls need 1 + the 10-digit number.

Of the 378 US area codes now in service, just 54 still take 7-digit local calls.
