On March 28, 2015 zone code 629 was authoritatively placed into administration as an overlay of territory code 615. Successful February 28, 2015, ten-digit dialling in the 629 and 615 region codes got obligatory.
Ten digit dialling (zone code + seven-digit number) is vital in the 615/629 overlay because various homes in a similar geographic region can have an equal seven-digit telephone number yet each would have an alternate territory code.

Spots in Tennessee inside region code 615 include:
At the point when region codes were presented in October 1947, Tennessee's just zone code was 901. During 1954, instantly cut, the vast majority of the state east of the Tennessee River's western curve was appointed 615, while 901 was confined to Memphis and the third of the west of the state. This setup stayed set up for more than 41 years.
In September 1995, the more significant part of the eastern bit of 615—including Chattanooga, Knoxville, and the Tri-Cities—was appointed region code 423. The isolating line somewhere in the range of 615 and 423, for the most part, followed along with the limit between the Eastern and Central Time Zones; by and large, a lot of the Eastern Time Zone moved to 423. The 615 area code was part of framing zone code 931.
Therefore, the state's three region codes were generally coextensive with the customary Grand Divisions of Tennessee; 423 served practically all of East Tennessee, 615 served virtually all of Middle Tennessee, and 901 did almost all of West Tennessee.
Nashville metropolitan zone
Even though this was planned to be a drawn-out arrangement, inside a year 615 was approaching fatigue because of the rapid development of the Nashville region, just as the expansion of PDAs and pagers.
This constrained one more split in September 1997; the 615 areas was diminished to its present size, while the more significant part of the western, southern, and eastern bits of the old 615 domain—including Clarksville, Cookeville, Columbia, and Tullahoma—was separated as zone code 931, which now, as a rule, encompasses 615. This made 615 to a great extent coextensive with the internal ring of the Nashville metropolitan zone.
