Important Note: As of February 2015, ten-digit dialing (including the area code) is mandatory for all calls within the 615/629 overlay area, even for local calls.

The 629 Overlay: Expanding Capacity

As Nashville grew, the available phone numbers within the 615 area code dwindled. To address this, the 629 area code was introduced as an overlay in 2014. An overlay means that both 615 and 629 serve the same geographic area. This is why ten-digit dialing is now required ??? the area code distinguishes between the two sets of numbers. This was a significant change in dialing practice for the region, and understanding this context is vital for anyone using the 615 area code.
