404 Area Code: Atlanta, Georgia

Atlanta is the primary city of the 404 area code, the original code for the Atlanta region and a designation tightly tied to the city's downtown and inner core. Atlanta sits on a high ridge above the headwaters of the Chattahoochee River, in the rolling Piedmont country of north Georgia, and the city's working profile reflects a long-running role as the commercial, transportation, and corporate center of the southeast — a role anchored by one of the world's busiest airports, the Coca-Cola Company headquarters, the CDC, and a substantial concentration of banking and media employment. The 404 footprint covers the city itself.

Records the directory has compiled for 404 numbers frequently include other Georgia cities — Albany, Columbus, Macon, and Sandy Springs among them. None of those are inside the 404 footprint. Their appearance reflects standard public-record dynamics, with phone numbers porting across the state and addresses linked across multiple cities. The directory currently documents 696 distinct prefixes within 404 in detail, a working subset of the prefix population the code carries.

Atlanta's home values come in well above the US median, in line with broader Atlanta-metro housing pressure that has lifted prices substantially over the past decade. Median household income runs above the national reading, and the city's median age sits a few years under the US figure. Population places Atlanta among the larger cities in the southeastern United States, the anchor of a metropolitan area that extends across multiple counties and pulls steadily on populations from across the surrounding region.
