The area code 629 is located in Brentwood, Tennessee.
Area code 629 serves Brentwood, Tennessee, as part of an overlay with area code 615 across the Nashville metropolitan area. Brentwood sits just south of Nashville in Middle Tennessee and is known for its parks, neighborhoods, and quick access to I-65. The 629 overlay was introduced in 2014 to add more phone numbers without changing the region’s boundaries.

Major cities and communities covered by the 615/629 area codes include:
Brentwood highlights within this coverage area include Crockett Park and Marcella Vivrette Smith Park, while nearby Nashville landmarks range from the Country Music Hall of Fame to major sports venues. The region follows the Central Time Zone (CT) and anchors business, health care, music, and tech for Middle Tennessee. Nearby, area code 931 serves outer Middle Tennessee, while 629/615 focuses on the core metro. For anyone needing a local number in Brentwood, 629 offers fresh numbering options without changing how calls route in the area.
