Area code 615

About area code 615

NANPA lists 615 as an in-service geographic area code for Tennessee, first put into service on January 1, 1954. It is an overlay: 615 and 629 cover the same territory, so neighbors on the same street can have different area codes. It is in the Central time zone. The places with the most assigned exchanges include Nashville-Davidson, Murfreesboro, Franklin, Goodlettsville, and Smithville. By population, its largest named places are Nashville-Davidson, Murfreesboro, Franklin, Hendersonville, and Smyrna.

Carriers with 615 numbers

34 carriers hold the 781 central office codes assigned in 615. Bellsouth Telecomm INC d/b/a South Central Bell Tel has the most, with 223 (29%). 504 of the codes (65%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.
