Atlanta GA Area Code Guide: ZIP Codes, Time Zone, Neighborhoods & Calling Info (2026)
If you received a call from an unfamiliar Atlanta number, are moving to the city, or need a local number for your business, the first question is simple: what is the Atlanta area code? The answer is slightly more interesting than most cities. Atlanta is served by not one but five area codes — 404, 678, 470, 770, and 943 — all covering the same metro region through one of the largest overlay systems in the United States. Add in dozens of ZIP codes, the Eastern Time Zone, and a mosaic of neighborhoods from Buckhead to East Atlanta, and there is a lot to unpack.
This guide brings it all together: every Atlanta area code and how it came to be, the main ZIP codes by neighborhood, the time zone rules that matter when you call, and how dialing works in a five-code overlay city.
What Area Code Is Atlanta?
Atlanta does not have a single area code. Five codes share the same geographic territory across the metro area: 404, 678, 470, 770, and 943. Because of the overlay plan, any of these codes can appear on a phone in downtown Atlanta, a Buckhead office, or a Marietta suburb — the code no longer tells you exactly which side of town someone is on.
Here is how the five codes came to exist:
404 — the original (1947). Area code 404 was one of the original North American area codes assigned in 1947, and it covered the entire state of Georgia. As the state grew, 404 was cut down by splits until it served only Atlanta. It is the cultural icon of the group: when people say “the 404,” they mean Atlanta itself. Businesses still prize 404 numbers, and they are the hardest to find new.
770 — the suburban split (1995). On August 1, 1995, the suburbs outside the I-285 perimeter were split off into area code 770, covering cities like Marietta, Roswell, Alpharetta, Lawrenceville, and Smyrna across roughly 29 counties. For a few years, 404 meant the city and 770 meant the suburbs.
678 — the first overlay (1998). Growth kept devouring numbers, so in 1998 area code 678 was added as an overlay across both 404 and 770 territory — the same geography, a new code layered on top. From that point on, callers in metro Atlanta had to dial all ten digits for local calls, because the code alone no longer identified a distinct zone.
470 — the second overlay (2001/2010). The Georgia Public Service Commission approved 470 on September 2, 2001, as another overlay for the same region, but large-scale number assignments did not begin until around 2010. It serves exactly the same footprint as 404, 770, and 678.
943 — the newest overlay (2022). Demand never stopped, so 943 was activated on March 15, 2022, as the fifth code in the complex. New numbers issued today across metro Atlanta are most likely to carry 943, 470, or 678 prefixes, simply because 404 blocks are nearly exhausted.
Within this five-code complex, every call is local. A 404 caller and a 943 caller in Atlanta are on the same local call — no long-distance charges apply between any of the codes, and your existing number never changes when a new code is added.
Atlanta ZIP Codes
Atlanta’s ZIP codes run mainly in the 303xx range, with inner suburbs reaching into 300xx, 301xx, and 302xx. The city of Atlanta itself has more than 40 ZIP codes. Here are the ones you are most likely to encounter:

Beyond the city limits, the metro area fans out into familiar codes: 30030 (Decatur), 30032 (East Lake/Decatur), 30067 (Marietta), 30075 (Roswell), 30076 (Roswell), 30092 (Norcross), 30096 (Duluth), 30101 (Acworth), 30144 (Kennesaw), 30319 (Brookhaven), 30328 and 30338 (Sandy Springs), 30341 (Chamblee), 30346 (Dunwoody), and 30213 (Fairburn), among many others.
Atlanta Time Zone
Atlanta is in the Eastern Time Zone: UTC-5 during Eastern Standard Time (EST) and UTC-4 during Eastern Daylight Time (EDT). Daylight saving time is observed, with clocks springing forward in March and falling back in November, matching New York, Washington, and Miami.
This matters more than people expect. Because Atlanta is a major business hub — home to Coca-Cola, Delta Air Lines, Home Depot, and UPS, and the busiest airport in the world in Hartsfield-Jackson — calls and video meetings routinely cross time zones. If you are calling Atlanta from the West Coast, remember the three-hour gap: 9 a.m. in Los Angeles is noon in Atlanta. From Chicago it is one hour; from Denver, two. And during the summer half of the year, Arizona (which does not observe daylight saving) lines up with Pacific Time, putting it three hours behind Atlanta as well.
Atlanta Neighborhoods and Their Area Codes
Since all five area codes cover the whole metro, the neighborhood does not determine the code — but newcomers and visitors still want to know the lay of the land. Here are the neighborhoods that define Atlanta, roughly from north to south:
Buckhead is Atlanta’s upscale north side, known for luxury shopping at Lenox Square and Phipps Plaza, fine dining, and some of the most expensive real estate in the Southeast. ZIPs 30305, 30326, 30327, and 30342 anchor it.
Midtown is the city’s dense urban heart: high-rise apartments, the Fox Theatre, Piedmont Park, the High Museum of Art, and a major LGBTQ+ community. ZIPs 30308 and 30309.
Downtown holds the business district, Centennial Olympic Park, the Georgia Aquarium, the World of Coca-Cola, and the Martin Luther King Jr. National Historical Park nearby. ZIPs 30303 and 30313.
Virginia-Highland and Morningside offer historic bungalows, boutique shopping, and a village feel just east of Midtown. ZIP 30306.
Inman Park, Old Fourth Ward, and Candler Park form the eastside’s historic core — Victorian homes, the Atlanta BeltLine trail, and a strong restaurant and bar scene. ZIPs 30307 and 30308.
West Midtown / the Westside is the converted-warehouse district of design showrooms, breweries, and new apartments around Howell Mill Road. ZIPs 30318 and 30363.
Grant Park is home to Zoo Atlanta and some of the city’s grandest Victorian architecture, south of downtown. ZIP 30312.
East Atlanta Village is the city’s indie-music and dive-bar hub, anchored by ZIP 30316.
Whichever neighborhood you land in, your phone number could carry any of the five area codes. A 770 number does not mean the suburbs anymore, and a 404 number does not guarantee downtown — the overlay erased those old boundaries.
How to Dial Atlanta Numbers
Because five area codes overlap the same territory, 10-digit dialing is mandatory for all local calls in metro Atlanta. You must dial the area code plus the seven-digit number even when calling your next-door neighbor.
- Local calls: dial all 10 digits (for example, 404-555-0123). No “1” prefix is needed for local calls on most carriers.
- Long distance within the US: dial 1 + area code + number.
- International: dial your country’s exit code, then 1 (the US country code), then the area code and number — for example, +1 678-555-0199.
- Toll-free and emergency: 911 and 311 work as always, unaffected by the overlay.
One practical note for businesses: new 404 numbers are scarce, so providers typically issue fresh Atlanta lines with 470, 678, or 943 prefixes. These work identically and cost the same to call.
Frequently Asked Questions
What is the main area code for Atlanta, Georgia?
The original and most recognized is 404, in service since 1947. However, Atlanta is officially served by five area codes — 404, 678, 470, 770, and 943 — all covering the same metro region.
Is 404 or 770 the Atlanta area code?
Both. Area code 404 covers the city core and 770 was split off for the suburbs in 1995, but the 1998 overlay (678) and later overlays (470, 943) erased the geographic split. Today all five codes serve the entire metro area.
What time zone is Atlanta, GA in?
Atlanta is in the Eastern Time Zone (UTC-5 standard, UTC-4 daylight). It observes daylight saving time from March to November.
What ZIP code is downtown Atlanta?
Downtown Atlanta is primarily 30303, with 30313 covering the Centennial Park and stadium district on the west side of downtown.
Do I need to dial the area code for local calls in Atlanta?
Yes. Ten-digit dialing is mandatory for all local calls in the Atlanta metro because five area codes share the same calling area.
Is a 943 or 470 number a scam number?
No. Area codes 943 and 470 are legitimate FCC-assigned overlays for metro Atlanta. As with any big city, scammers sometimes spoof local numbers, but the codes themselves are genuine.
Conclusion
The Atlanta area code story mirrors the city’s growth: one code in 1947, a 1995 suburban split, and three overlays since — leaving 404, 678, 470, 770, and 943 serving a metro of six million on Eastern Time. Dial ten digits, mind the time zone when scheduling, and use the ZIP code — not the area code — to pin down a neighborhood.
