In 1954, 912 was given to its southern and central areas. The state would operate with two area codes until May 3, 1992, when 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.〔(Area code 470 usage )〕 In September 2005, 762 was overlaid to all of the existing area code 706, despite the fact that that it has been physically split into two separate and disconnected sections since it was created in 1992.〔(Overlay map from BellSouth )〕 There are currently nine area codes serving Georgia, with no plans for new ones. None of the codes are expected to exhaust in the next 20 years.〔http://www.nanpa.com/pdf/NRUF/April_2014_NPA_Exhaust_Projections.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of Georgia area codes」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
