Where Is Area Code 470?

Area code 470 serves the Atlanta metropolitan area in north-central Georgia. It covers the same general region as area codes 404, 678, and 770. This service area includes the city of Atlanta and many nearby suburbs and communities across metro Atlanta.

Area code 470 is used in major cities and communities such as Atlanta, Sandy Springs, Roswell, Alpharetta, Marietta, Smyrna, Decatur, and Johns Creek. It also appears across parts of counties that are commonly tied to metro Atlanta, including Fulton, DeKalb, Cobb, Gwinnett, and Clayton counties. The area code follows the region of one of the largest telephone service markets in the state.

The 470 area includes well-known places in and around Atlanta. These include Hartsfield-Jackson Atlanta International Airport, downtown Atlanta, and major institutions such as Georgia State University and Georgia Tech. The region sits in the Piedmont area of Georgia and is centered around the city of Atlanta.

History of Area Code 470

Area code 470 was established in 2010 as an overlay for the existing 404, 678, and 770 area codes in the Atlanta area. The Georgia Public Service Commission approved the overlay to add more telephone numbers without changing existing numbers in the region. New 470 numbers began appearing after the overlay took effect.

The Atlanta phone system grew through both splits and overlays over several decades. Area code 404 originally covered a much larger part of Georgia, but 770 was created in 1995 for suburbs outside the city, and 678 was added in 1998 as an overlay. Area code 470 expanded the same overlay complex as demand for mobile phones, fax lines, and other services continued to grow.
