It serves San Francisco and its northern suburbs in Marin County (across the Golden Gate Bridge), and the northeast corner of San Mateo County. It has been overlaid with area code 628 since February 21, 2015.〔http://www.cpuc.ca.gov/PUC/Telco/generalInfo/Area+Codes/415+Area+Code.htm〕 ==History== 415 was one of the original three area codes in California, established in 1947. It originally covered central California, south of area code 916 and north of area code 213. It stretched from Sacramento in the north to Bakersfield in the south. In 1950, 415 was extended along the North Coast to the Oregon border, while 916 was rotated to cover the northeastern corner of the state. As part of this realignment, Sacramento was shifted from 415 to 916, while Bakersfield moved to 213. For a short time in the early 1950s, area code 318 was temporarily used, initially by customers in Englewood, New Jersey participating in the first customer direct distance dialing experiment to reach San Francisco as well as some areas north of the Golden Gate. In 1953, the entire Bay Area was "reunited" in using area code 415. Area 415 has been split three times due to the Bay Area's rapid growth: * On March 1, 1959, in a three-way split, area code 707 was created for the North Coast (excluding Marin County) and area code 408 for San Jose and the South Bay. * On September 2, 1991, area code 510 was created for the East Bay, including Oakland. * On August 2, 1997, area code 650 was created; the partition approximately followed the boundary between San Francisco, which (along with Marin County) kept 415, and San Mateo County to the south, which received the new code. Deviations from the county line were a very small area east of the San Francisco Golf Club, which was changed to 650, and portions of Brisbane and Daly City, which retained area code 415. On 21 February 2015, area code 628 was as an overlay for newly assigned phone numbers in the 415 territory, making ten-digit dialing mandatory in the area.〔("415, meet 628: New S.F. area code debuts Saturday" )〕 415 had been one of the few urban area codes that had not been overlaid, making San Francisco one of the largest cities where seven-digit dialing still functioned. 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 codes 415 and 628」の詳細全文を読む スポンサード リンク
