Created in 1954 after a split from 901, 615 once covered much of Tennessee before later changes. Eastern Tennessee moved to 423 in 1995, and outer Middle Tennessee shifted to 931 in 1997, leaving 615 focused on the Nashville area and Murfreesboro. The 629 overlay was added in 2014 to meet demand, so 10‑digit dialing is required for local calls. If you get a new phone number in Murfreesboro, it may be 615 or 629, but both serve the same region and connect you to the heart of Middle Tennessee.
