Area code 407 is the area code centered principally on Orlando, Florida, but also including all of Orange, Osceola, and Seminole counties, as well as small portions of Volusia and Lake counties. From 1947 until 1988, the region now using 407 was part of the 305 area code, which included the east coast from Brevard County southward, including the Florida Keys. After the split, 407 included the former 305 area code from Palm Beach County northward, and the Greater Orlando metro area. In 1996, Palm Beach, Martin, Indian River, and St. Lucie counties were split from the 407 Area code to form the 561 area code. The 561 area code has since split forming area code 772. In October 2000, the Brevard County portion of 407 became the 321 area code. Aside from the small portions of Volusia County (the Deltona area) which continued to use only 407, the remainder of 407 (Orange, Osceola, and Seminole counties) was overlaid with the new 321 area code. In 2003, it was announced that all new phone numbers in the three counties would no longer be issued 321, although then-321 numbers in the Orlando metro area would keep that area code. In 2001, Deltona was switched to Area code 386 when 386 was split from 904. All of 407 is now overlaid with 321. Area code 689 has been allocated as a future overlay area code, although the exact overlay pattern of 689 has not yet been determined. ==See also== *List of Florida area codes *List of NANP area codes *North American Numbering Plan 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「area code 407」の詳細全文を読む スポンサード リンク
