The Tennessee Regulatory Authority (TRA) ordered an area code overlay adding the 629 area code to the 615 area. This affects the north-central portion of the state of Tennessee serving communities such as Franklin, Gallatin, Hendersonville, Lebanon, Murfreesboro, Nashville and Springfield.
Prior to March 28, 2015 – No Impact: Customers will continue to be able to complete calls to others in the 615 area using 7-digits, 10-digit or 1+10-digit dialing pattern.

March 28, 2015 & After: Impact New customers in the above-named communities will be assigned the 629 area code beginning March 28, 2015. Customers with 615 area codes attempting to reach persons within the new 629 area code will need to utilize 10-digit or 1+10-digit dialing.
