Georgia’s telephone numbering plan, administered by the North American Numbering Plan Administration (NANPA), consists of the following area codes for the U.S. state of Georgia. Each code is associated with a geographic region, though overlays mean that multiple codes can serve the same area.
| Area Code | Primary Coverage Region(s) | Notes |
|---|---|---|
| 229 | Southwestern Georgia – cities such as Albany, Valdosta, Thomas Valley, and Moultrie | Established 2001 (split from 912) |
| 404 | Central Atlanta metropolitan core | Original Georgia code (est. 1947); now an overlay area |
| 470 | Atlanta metropolitan area (overlay) | Overlay for 404, 678, and 770; introduced 2001 |
| 478 | Central Georgia – Macon, Warner Robins, Fitzgerald, and Jefferson | Split from 912 in 2001 |
| 678 | Atlanta metropolitan area (overlay) | Overlay for 404, 470, and 770; introduced 1998 |
| 706 | North‑central and eastern Georgia – Athens, Augusta, Columbus, and Dalton | Split from 404 in 1992 |
| 762 | Atlanta‑adjacent northern/eastern region (overlay) | Overlay for 706; introduced 2005 |
| 770 | Atlanta suburbs – Marietta, Alpharetta, Roswell, and surrounding counties | Split from 404 in 1995 |
| 912 | Coastal and southeastern Georgia – Savannah, Brunswick, Waycross, and the Sea Islands | Original southwestern/southeastern code (est. 1947); reduced after 229 and 478 splits |
Additional Information
- Overlays: In the Atlanta market, area codes 404, 470, 678, and 770 function as overlays, meaning that new telephone numbers may be assigned any of these codes regardless of precise location within the metropolitan area.
- Regulatory Authority: The Georgia Public Service Commission (PSC) coordinates with NANPA for area‑code relief planning and changes.
- Historical Changes: The original area code for the entire state was 404 (assigned in 1947). Subsequent splits and overlays have created the current set of nine distinct codes, covering the entire state without any gaps.
This list reflects the area codes in official use as of July 2026. Future changes may be announced by NANPA or the Georgia PSC.
