Area codes 805 and 820
Area codes 805 and 820 are California telephone area codes; 805 was originally split from area code 213 in 1957. They include most or all of the California counties of San Luis Obispo, Santa Barbara, Ventura, plus the southernmost portions of Monterey County.
On February 13, 1999, area code 805 was split, with area code 661 having been created for the inland areas, which are the San Joaquin Valley, Santa Clarita Valley, and Antelope Valley.
Area code 805 also serves the US military facilities in Kwajalein, Republic of the Marshall Islands with a Paso Robles prefix. This arrangement originated from the US Army's first satellite communications station having been built at nearby Camp Roberts.
In August 2016, the California Public Utilities Commission held a series of hearings regarding the potential need to provide a relief area code for 805 in the form of an overlay or a split. On May 25, 2017, the Commission approved 820 as an overlay area code. New telephone numbers with the 820 area code began service in June 2018. Those who fail to add the 805 or 820 before the number risk a recorded message to remind them.Places in the 805/820 area codes
