List Of California Area Codes
__NOTOC__ In 1947, the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes. The state of California was divided into three numbering plan areas (NPAs) with distinct area codes: 213, 415, and 916, for the southern, central, and northern parts of the state, respectively. In 1949, Oakland, CA, received the fifth regional dial switching center for Operator Toll Dialing in the nation, which set the stage for direct distance dialing by customers in the 1950s. In 1950, the boundaries of the California numbering plan areas were redrawn to produce a division of the northern and central parts along a north–south-running dividing line. Numbering plan area 415 became the coastal region from the North Coast to the Oregon border, while 916 was redrawn to comprise the northeastern corner of the state. This realignment resulted in Sacramento changing from area code 415 to 916, and Bakersfield ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Code 279
Area codes 916 and 279 are telephone area codes in the North American Numbering Plan for Sacramento, the state capital, and most of its suburbs. Area code 916 was one of the first three original area codes established in California in October 1947, originally assigned to the most northern part, but remapped in 1950 to the northeast.
