History[edit source | edit]
Area code 423 was created in 1995 when it was split off from area code 615. It was the state's first new area code in 41 years. Originally it consisted of the eastern third of the state. The boundary between 423 and 615 roughly followed the line between the Eastern and Central time zones; generally, Tennessee's share of the Eastern Time Zone was in 423. As a result, the state's three area codes were roughly coextensive with the traditional Grand Divisions of Tennessee; 423 served almost all of East Tennessee, 615 served Middle Tennessee and 901 served West Tennessee.
