This is a list of area codes in the U.S. state of Georgia.
In 1947, Georgia was a single numbering plan area (NPA) with area code 404. In 1954, 912 was assigned to its southern and central areas.
The state operated with two area codes until May 3, 1992, when area code 706 was created for the two separate areas outside of the metro Atlanta area. Due to complaints from exurban residents who were to be put in 706, they were moved back into 404, which makes every new area code added to the metro area run out of numbers sooner. At this time, these areas were also fully included in what was already the world's largest toll-free local calling zone (previously many were only able to call the adjacent telephone exchanges on the edge of metro Atlanta). Area code 770 was therefore assigned to Atlanta's suburbs just three years later in August 1995, requiring ten-digit dialing between them, and with all mobile phones keeping 404. 678 was given to both the city and its suburbs in January 1998, becoming the first overlay area code in the state, and forcing mandatory ten-digit dialing for all calls.
Flip-flopping on its position on assigning new area codes, the Georgia Public Service Commission dictated that a double split of 912 would occur after that, with 229 and 478 being applied to southwest Georgia and central Georgia in August 2000. With the GPSC reversing course a third time, 470 became the second area code to overlay Atlanta in September 2001, but remained unused until 2010. [1] In September 2005, 762 was overlaid to all of the existing area code 706, despite the fact that it has been physically split into two separate and disconnected sections since it was created in 1992. [2]
Georgia is served by ten area codes. The newest area code, 943, went into service in March 2022 as another area code for the Atlanta area. [3] Current projections suggest that both 229 and 912 will require further relief before 2030. [4]
Mobile numbers in metro Atlanta may now have 404, 470, 678, 770, or 943 after originally being kept in 404 by BellSouth.
Area codes 905, 289, 365, and 742 are telephone area codes in the North American Numbering Plan (NANP) for the Golden Horseshoe region that surrounds Lake Ontario in Southern Ontario, Canada. The numbering plan area (NPA) comprises (clockwise) the Niagara Peninsula, the city of Hamilton, the regional municipalities of Halton, Peel, York, Durham, and parts of Northumberland County, but excludes the City of Toronto.
Area codes 519, 226, 548, and 382 are overlay telephone area codes in the North American Numbering Plan (NANP) for most of southwestern Ontario.
Area codes 613, 343, and 753 are telephone area codes in the North American Numbering Plan (NANP) for Ottawa and surrounding Eastern Ontario, Canada. Area code 613 is one of the 86 original North American area codes assigned in October 1947. Area code 343 was assigned to the numbering plan area in an overlay plan activated on May 17, 2010. Area code 753 was assigned as an additional overlay code for the numbering plan area, activated on March 26, 2022.
In telecommunications, an area code overlay complex is a telephone numbering plan that assigns multiple area codes to the same geographic numbering plan area (NPA). Area code overlays are implemented in territories of the North American Numbering Plan (NANP) to mitigate exhaustion of central office codes in growth areas. The method has been in use since 1992, and has been the exclusive method of area code relief since 2007.
Area code 404 is a telephone area code in the North American Numbering Plan (NANP) for Atlanta, Georgia and its closest suburbs. This comprises roughly the area encircled by Interstate 285. It is an enclave area code, surrounded by area code 770, which serves most of Atlanta's suburbs. Both 404 and 770 are overlaid by area codes 678, 470, and 943.
Area codes 706 and 762 are telephone area codes in the North American Numbering Plan (NANP) for the northern and west central parts of Georgia, but excluding metropolitan Atlanta.
Area code 250 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of British Columbia outside the Lower Mainland, including Vancouver Island–home to the provincial capital, Victoria–and the province's Interior region. In addition, the numbering plan area extends into the United States community of Hyder, Alaska, located along the Canada–United States border near the town of Stewart. The incumbent local exchange carriers that service the area code are Telus, Northwestel, and CityWest in the city of Prince Rupert.
Area codes 204, 431, and 584 are telephone area codes in the North American Numbering Plan (NANP) for the Canadian province of Manitoba. Area code 204 is one of the nine original North American area codes assigned to Canada in 1947. Area codes 431 and 584 were assigned to the same numbering plan area (NPA) in 2012 and 2022, respectively, forming an overlay complex.
Area codes 778, 236, and 672 are telephone area codes in the North American Numbering Plan (NANP) for the Canadian province of British Columbia. They form an overlay complex with area code 604, which serves only a small southwestern section, the Lower Mainland, of the province, and area code 250, which serves the rest of the province.
Area code 403 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of Alberta. The numbering plan area encompasses the southern third of the province, which includes the Calgary area. This numbering plan area is also served by area codes 587, 825, and 368, which form a complex overlay for all of Alberta.
Area code 780 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of Alberta. The numbering plan area comprises the northern two thirds of the province, including the Edmonton area. The area code was established in 1999 in a split of area code 403, which had served the entire province since the establishment of the original North American area codes in 1947. The numbering plan area is also served by area codes 587, 825, and 368, which form a complex overlay for all of Alberta.
Area code 709 is the telephone area code in the North American Numbering Plan (NANP) for the entire Canadian province of Newfoundland and Labrador.

The area code is one of the nine original North American area codes assigned to Canada in 1947.
Area code 770 is a telephone area code in the North American Numbering Plan (NANP) serving all or part of 29 counties in North Georgia, including most of Atlanta's suburbs. It was created in 1995 in a split of numbering plan area (NPA) 404.
Area codes 678, 470, and 943 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. State of Georgia in the Atlanta metropolitan area. The area codes are assigned in an overlay plan to a combined numbering plan area (NPA) consisting of 404 and 770.
Area codes 410, 443, and 667 are telephone area codes in the North American Numbering Plan (NANP) for the eastern half of the U.S. state of Maryland. The numbering plan area (NPA) includes the Baltimore metropolitan area and the Eastern Shore. The three area codes are overlay codes for one numbering plan area, among which 410 was the initial area code for the NPA, when it was split from area code 301 in 1991. 443 and 667 found assignment primarily in cellular service and for competitive local exchange carriers, such as Comcast and Cavalier Telephone, when introduced, but have since become universal in carrier availability.
Area code 912 is a telephone area code in the North American Numbering Plan (NANP) for the southeastern part of the U.S. state of Georgia. The numbering plan area contains Savannah, Richmond Hill, Hinesville, Vidalia, Metter, Reidsville, Homerville, Waycross, Brunswick, Folkston, Douglas, Statesboro, Ludowici, Jesup and Kingsland.

In the administration of the North American Numbering Plan, central office code protection is a numbering policy for maintaining local seven-digit dialing in communities that extend on both sides of the boundary line between multiple numbering plan areas (NPAs), such as in cross-border towns on state lines. Code protection prevents the use of the same telephone number on both sides by not assigning the same central office code of one NPA in the adjacent NPA.
