Area code 404 covers the central core of Atlanta, Georgia, including downtown and nearby neighborhoods. It is one of the original North American area codes established in 1947 and remains a symbol of Atlanta’s cultural and commercial significance. Due to population growth, 404 has been supplemented by several overlays including 678, 470, and 943, requiring ten-digit dialing. Despite this, 404 retains prestige and legacy value, frequently referenced in music, branding, and media. It has become a cultural shorthand for Atlanta itself, representing its leadership in entertainment, civil rights, and Southern urban life.
