If you live in Atlanta, travel here often, or are trying to reach someone in the city, it helps to know that Atlanta does not have just one area code. Instead, the Atlanta metro area uses multiple overlaying area codes that all serve the same general region.
The major area codes for Atlanta, Georgia, are:
Understanding how these Atlanta area codes work will make it easier to dial local numbers, set up phone service, and recognize where calls might be coming from.
404 is the historic and most recognized area code for Atlanta. It mainly covers the City of Atlanta and nearby intown communities, commonly associated with:
Many long-time Atlanta residents and businesses still have 404 numbers, and the code has become part of the city’s identity.
As the region grew, 770 was added to serve many suburban areas outside the I-285 perimeter, including parts of:
If you’re calling a business or home in the metro suburbs, you’ll often see a 770 number.
Because Atlanta’s population and phone usage kept growing, 678 and later 470 were introduced as overlay area codes. That means:
It’s common for new cell phones, internet-based lines, and some home services to be issued 678 or 470 numbers, even for addresses in the heart of Atlanta.
More recently, 943 was added as another overlay area code for the Atlanta metro. As existing codes fill up, new numbers in the region may be assigned a 943 area code.
You may not see 943 as often yet, but it functions just like 404, 470, 678, and 770 in the Atlanta area.
| Area Code | Type | General Use in Atlanta |
|---|---|---|
| 404 | Original | Core City of Atlanta and close-in neighborhoods |
| 770 | Split/Overlay | Suburban metro areas outside much of the I-285 loop |
| 678 | Overlay | Metro-wide overlay (city + suburbs) |
| 470 | Overlay | Metro-wide overlay for new lines |
| 943 | Overlay | Newest metro-wide overlay as numbers are added |

When giving your number to friends, delivery services, or local businesses, include the area code.
Program contacts with area codes.
Save numbers as 404-XXX-XXXX, not just seven digits, so they work correctly when you travel or change devices.
