The community has maintained a distinctive identity, centered on its public high school, churches, and locally owned and operated businesses such as the Cofer Brothers building supply business, Matthews' Cafeteria, and the Tucker Federal savings and loan association (although the latter institution was merged into RBC Centura). It also has been designated with its own ZIP code of 30084.
In 2005, the Atlanta Regional Commission issued Tucker a grant to develop a Livable Cities Initiative (LCI). The LCI study, published in December 2005, will look to reestablish Main Street in Tucker as a central point for the greater Tucker community. The study will help create a more pedestrian-friendly and interconnected town center by encouraging walking and other modes of transportation to and around the commercial core. Similarly in August 2004, the Tucker Civic Association created a Neighborhood Strategic Plan to assist in the development of the neighborhood.
