Area codes 805 and 820 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. The numbering plan area (NPA) includes most or all of the counties of San Luis Obispo, Santa Barbara, Ventura, and the southernmost portions of Monterey County. 805 was split from area code 213 in 1957, and area code 820 was added to the NPA in 2018, creating an area code overlay.
History
Area code 805 was created in 1957, when one of the original North American area codes in California, 213, was reduced in size to provide more central office codes in the Los Angeles area.
In 1998, the California-Nevada Code Administration (CNCA) determined that California was under "substantial number growth" which required exhaustion mitigation in the 805 numbering plan area,[1] by splitting the eastern part of the NPA into a new plan area with the area code 661. The split was effective on February 13, 1999 for the San Joaquin Valley, Santa Clarita Valley, and Antelope Valley.
In August 2016, the California Public Utilities Commission held a series of hearings for the decision of providing a relief area code in NPA 805 in the form of an overlay or an area code split.[2] On May 25, 2017, the Commission approved 820 as an overlay area code.[3][4] New telephone numbers of 820 area code began service in June 2018, requiring ten-digit dialing for all calls.[5]
In addition to the municipalities below, area code 805 also serves the US military facilities in Kwajalein, Republic of the Marshall Islands with a Paso Robles prefix (805-355). This arrangement originated from the US Army's first satellite communications station having been built at nearby Camp Roberts.
