Feature Answer

What is Area Code 404?

Area code 404 is a North American telephone area code assigned to Atlanta, Georgia. First assigned in 1947 as one of the original 86 area codes in the North American Numbering Plan, 404 is among the oldest and most recognized area codes in the country. It serves Atlanta proper, including downtown, Midtown, Buckhead, and most neighborhoods inside Interstate 285, and is a local (non-toll-free) area code in the Eastern Time Zone.

404 originally covered all of Georgia. As Atlanta's growth accelerated, splits in 1992 (706 for north and central Georgia) and 1995 (770 for the Atlanta suburbs) gradually carved 404 down to just the city core. Overlay 678 was added in 1998, and 470 in 2010. Despite multiple overlays, '404' remains a cultural and business identifier for Atlanta — referenced in music, sports, and local pride.
