1. History
The first code assigned to Tennessee State was the 901 area code, which used to surround the entire Tennessee Territory, being one of the 86 original dialing numbers in the North American Numbering Plan, established in 1947.
Seven years later, on January 1, 1954, the 615 area code was established as the second code in the state, restricting the 901 code to Memphis and the western portion of the region and covering the eastern two-thirds of Tennessee.
AT&T and the Bell System have split the prefix 615 twice since its introduction. The first division was in September 1995, to create the 423 area code, which surrounded the eastern portion of the 615 code. Then, the second split occurred in 1997, with the establishment of the 931 area code, assigned to Middle Tennessee.
On October 21, 2013, the 629 area code began serving as part of an overlay plan for Davidson County and its surrounding regions. At the moment, the prefix 629 is the only overlay for the 615 code, making ten-digit dialing necessary in this zone.
