If you live in Atlanta, Georgia, you’ve probably seen a mix of 404, 770, 678, and 470 on phones, billboards, and business cards. These are the main Atlanta area codes, and understanding how they’re used can help whether you’re setting up service, moving to the city, or just trying to figure out who’s calling you.
This guide walks through every major area code tied to Atlanta, how they’re assigned, and what it means for your phone service and daily life in the city.
Atlanta doesn’t have just one area code. It has a cluster of overlapping codes that cover the city and its suburbs.
Most common Atlanta-related area codes include:
| Area Code | Main Use in and Around Atlanta |
|---|---|
| 404 | Central Atlanta and nearby intown neighborhoods |
| 770 | Suburban metro Atlanta (north, east, west, and south) |
| 678 | Overlay for both 404 & 770 (city + suburbs) |
| 470 | Newer overlay for metro Atlanta and north Georgia |
| 943 | Overlay area code that can show up in the broader region |
Because of overlays, you can’t rely on an area code alone to tell exactly where in metro Atlanta a number is based, but you can get a general sense that the number is tied to the region.
The 404 area code is strongly associated with Atlanta proper and has become part of the city’s identity.

Over time, the lines between 404 and 770 areas have blurred as the metro area expanded. Some neighborhoods and businesses close to Atlanta may use 770 even if they feel “very Atlanta.”
Because both 404 and 770 became crowded, overlay area codes were added.
The 678 area code covers both city and suburbs, acting as an overlay to:
If you see a 678 number, it can belong to:
The 470 area code is another overlay across a large part of metro Atlanta and surrounding north Georgia. Like 678, it doesn’t map to a specific city or neighborhood.
For everyday use, 678 and 470 work just like 404 and 770, but:
Atlanta’s multiple area codes are mainly due to:
To keep up, regulators expanded from one area code to multiple overlays, instead of repeatedly changing everyone’s number.
