Area code 629 is an overlay to 615, serving the Nashville area and surrounding Middle Tennessee communities. Introduced in 2014, it was created due to population growth and demand in one of the country’s fastest-growing metros. While 615 remains the more recognized code, 629 is widely used for new numbers across Nashville’s booming economy. Ten-digit dialing is required. 629 represents the region’s expansion and the evolution of its role as a national hub for entertainment and business.
