About 678 Area Code
Area code 678 serves Atlanta and the metropolitan region. Created on January 6, 1998 as the first overlay for the existing 404 and 770 area codes, 678 covers the entire Atlanta metro area including Atlanta proper, Sandy Springs, Roswell, Alpharetta and surrounding cities across 29 counties. The code supports local voice and SMS-capable numbers used by Fortune 500 companies, small businesses, healthcare providers and service organizations throughout one of the nation's largest local calling areas.
The 678 region anchors one of America's most dynamic business ecosystems. Atlanta hosts headquarters for major corporations including Coca-Cola, Home Depot, Delta Air Lines and UPS, plus a thriving tech sector and financial services cluster. Businesses use 678 numbers for customer service lines, sales teams, appointment scheduling and field operations. A local Atlanta number signals community presence and typically yields higher answer rates than toll-free alternatives, especially when targeting residents and businesses across metro Atlanta's diverse neighborhoods and suburbs.
FoneSwift lists live 678 inventory and capabilities on this page. Search numbers to see which ones support Voice, SMS and MMS. Since 678 is part of a multi-code overlay (404, 470, 770, 943), availability can fluctuate; if a 678 number is not immediately available, nearby overlay codes serve the same geographic area and deliver identical local presence benefits for metro Atlanta audiences.
If your business targets Atlanta or the metro region, publish numbers in both local and E.164 formats (e.g., (678) 555-1234 and +1 678 555 1234) and register messaging traffic if you plan A2P campaigns. For porting, see our porting guide. Many businesses keep the same number to preserve customer recognition and search rankings. 10-digit dialing is mandatory throughout the Atlanta area, so callers within metro Atlanta must dial the full area code plus seven-digit number for all calls.

How Does Local 678 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 678 number in Atlanta and Georgia, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (678): directs the call to the Atlanta / Georgia region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 678 555 1234 |
| Local Format (National) | (678) 555-1234 |
