Area code 478 covers central Georgia, including cities such as Macon, Warner Robins, Milledgeville, and Dublin. It was created in 2001 from a split of area code 912, serving the heart of Georgia's interior. The region is notable for its military and aviation presence, particularly Robins Air Force Base, as well as for its deep roots in Southern culture and music history. Macon, the largest city in the 478 area, has strong ties to musical legends and a vibrant arts scene. The area code continues to serve both urban and rural communities and has not yet required an overlay. 478 remains a key part of Georgia's cultural and economic geography.
