404 Area Code
for Atlanta Businesses

The 404 area code serves Atlanta, Georgia and its closest suburbs in the North American Numbering Plan. Established in 1947 as one of the original area codes covering the entire state, it now serves the metro Atlanta core including Fulton, DeKalb, and Clayton counties.

Area code 404 holds the distinction of being one of the original 86 area codes created by AT&T and Bell System in 1947. When first established, it served the entire state of Georgia, making it one of the most geographically extensive area codes in the nation at the time. The rapid growth of Atlanta as a major Southern metropolitan hub created unprecedented demand for telephone numbers. The first major change occurred in 1954 when the southern portion of Georgia was split off to create area code 912. This division allowed 404 to focus on northern Georgia while 912 served cities like Savannah, Macon, and Valdosta. By the early 1990s, Atlanta's explosive growth—fueled by its emergence as a major transportation, financial, and cultural center—necessitated further changes. In 1992, area code 770 was created to serve Atlanta's sprawling suburbs, while 404 was restricted to the urban core and closest suburbs. However, this geographic split proved insufficient to handle the region's insatiable demand for phone numbers. In 1998, the North American Numbering Plan Administrator implemented an overlay plan, introducing area code 678 to serve the same territory as both 404 and 770. This marked a shift from geographic splits to overlay strategies. The trend continued with the addition of area code 470 in 2001 and, most recently, area code 943 in 2022. Today, 404 remains one of the most recognizable and prestigious area codes in the Southeast, symbolizing Atlanta's status as a major economic and cultural powerhouse.
