{{short description|Area codes in central California, United States}} {{California area codes image map|805}} '''Area codes 805 and 820''' are telephone [[area code]]s 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 County, California|San Luis Obispo]], [[Santa Barbara County, California|Santa Barbara]], [[Ventura County, California|Ventura]], and the southernmost portions of [[Monterey County, California|Monterey County]]. 805 was split from [[area code 213]] in 1957, and area code 820 was added to the NPA in 2018, creating an [[overlay plan|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,<ref>{{Cite web |url=https://www.nationalnanpa.com/pdf/pl-nanp-111.pdf |title=Planning Letter PL-111: NANP-Split of 805 (California) Numbering Plan Area (NPA) |publisher=NANPA |date=1988-02-12 |access-date=2023-02-27 }}</ref> 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 plan|overlay]] or an [[area code split]].<ref>{{Cite web|url=http://www.cpuc.ca.gov/805areacode/|title=805 Area Code|website=California PUC|language=en|access-date=2017-04-02}}</ref> On May 25, 2017, the Commission approved 820 as an overlay area code.<ref>{{Cite web |url=http://docs.cpuc.ca.gov/SearchRes.aspx?docformat=ALL&docid=187354351 |title=DECISION GRANTING REQUEST FOR AN ALL-SERVICE AREA CODE OVERLAY IN THE 805 NUMBERING PLAN AREA |date=2017-05-25|website=cpuc.ca.gov|access-date=2017-05-25 }}</ref><ref>{{Cite web |url=https://www.nationalnanpa.com/pdf/PL_509.pdf |title=Planning Letter PL-509: NPA 805 and 820 All-Services Overlay (California) |publisher=NANPA |date=2017-06-19 |access-date=2023-02-27 }}</ref> New telephone numbers of 820 area code began service in June 2018, requiring [[ten-digit dialing]] for all calls.<ref>{{cite web|url=https://www.vcstar.com/story/news/local/2018/05/28/new-area-code-changes-how-805-dial-ventura-county-san-luis-obispo/624048002/|title=New area code changes the way people dial in the 805 as of Saturday|newspaper=[[Ventura County Star]]|first=Tom |last=Kisken|date=2018-05-28|access-date=2018-05-29}}</ref> In addition to the municipalities below, area code 805 also serves the US military facilities in [[Kwajalein Atoll|Kwajalein]], [[Marshall Islands|Republic of the Marshall Islands]] with a [[Paso Robles, California|Paso Robles]] [[Telephone prefix|prefix]] (805-355). This arrangement originated from the [[United States Army|US Army's]] first satellite communications station having been built at nearby [[Camp Roberts, California|Camp Roberts]]. ==Service area== ===Monterey County=== {{Div col|colwidth=20em}} *[[Bradley, California|Bradley]] *[[Gorda, California|Gorda]] *[[Bryson, California|Bryson]] *[[Parkfield, California|Parkfield]] {{div col end}} ===San Luis Obispo County=== {{Div col|colwidth=20em}} *[[Arroyo Grande, California|Arroyo Grande]] *[[Atascadero, California|Atascadero]] *[[Avila Beach, California|Avila Beach]] *[[Baywood-Los Osos, California|Baywood-Los Osos]] *[[California Valley, California|California Valley]] *[[Cambria, California|Cambria]] *[[Cayucos, California|Cayucos]] *[[Cholame, California|Cholame]] *[[Grover Beach, California|Grover Beach]] *[[Halcyon, California|Halcyon]] *[[Harmony, California|Harmony]] *[[Lake Nacimiento, California|Lake Nacimiento]] *[[Los Osos, California|Los Osos]] *[[Morro Bay, California|Morro Bay]] *[[Nipomo, California|Nipomo]] *[[Oceano, California|Oceano]] *[[Paso Robles, California|Paso Robles]] *[[Pismo Beach, California|Pismo Beach]] *[[Pozo, California|Pozo]] *[[San Luis Obispo, California|San Luis Obispo]] *[[San Miguel, San Luis Obispo County, California|San Miguel]] *[[San Simeon, California|San Simeon]] *[[Santa Margarita, California|Santa Margarita]] *[[Shandon, California|Shandon]] *[[Templeton, California|Templeton]] {{div col end}} ===Santa Barbara County=== {{Div col|colwidth=20em}} *[[Ballard, California|Ballard]] *[[Buellton, California|Buellton]] *[[Carpinteria, California|Carpinteria]] *[[Casmalia, California|Casmalia]] *[[Garey, California|Garey]] *[[Gaviota, California|Gaviota]] *[[Goleta, California|Goleta]] *[[Guadalupe, California|Guadalupe]] *[[Hope Ranch, California|Hope Ranch]] *[[Isla Vista, California|Isla Vista]] *[[Lompoc, California|Lompoc]] *[[Los Alamos, California|Los Alamos]] *[[Los Olivos, California|Los Olivos]] *[[Mission Canyon, California|Mission Canyon]] *[[Mission Hills, Santa Barbara County, California|Mission Hills]] *[[Montecito, California|Montecito]] *[[Orcutt, California|Orcutt]] *[[Santa Barbara, California|Santa Barbara]] *[[Santa Maria, California|Santa Maria]] *[[Santa Ynez, California|Santa Ynez]] *[[Sisquoc, California|Sisquoc]] *[[Solvang, California|Solvang]] *[[Summerland, California|Summerland]] *[[Toro Canyon, California|Toro Canyon]] *[[Vandenberg Space Force Base|Vandenberg SFB]] *[[Vandenberg Village, California|Vandenberg Village]] *[[Ventucopa, California|Ventucopa]] {{div col end}} ===Ventura County=== {{Div col|colwidth=20em}} *[[Bardsdale, California|Bardsdale]] *[[Buckhorn, Ventura County, California|Buckhorn]] *[[Camarillo, California|Camarillo]] *[[Casa Conejo, California|Casa Conejo]] *[[Channel Islands Beach, California|Channel Islands Beach]] *[[El Rio, California|El Rio]] *[[Fillmore, California|Fillmore]] *[[La Conchita, California|La Conchita]] *[[Lake Sherwood, California|Lake Sherwood]] *[[Meiners Oaks, California|Meiners Oaks]] *[[Mira Monte, California|Mira Monte]] *[[Ventura, California|Montalvo]] *[[Moorpark, California|Moorpark]] *[[Newbury Park, California|Newbury Park]] *[[Oak View, California|Oak View]] *[[Ojai, California|Ojai]] *[[Oxnard, California|Oxnard]] *[[Piru, California|Piru]] *[[Point Mugu, California|Point Mugu]] *[[Port Hueneme, California|Port Hueneme]] *[[Santa Paula, California|Santa Paula]] *[[Saticoy, California|Saticoy]] *[[Simi Valley, California|Simi Valley]] *[[Somis, California|Somis]] *[[Thousand Oaks, California|Thousand Oaks]] *[[Ventura, California|Ventura]] {{div col end}} ==See also== *[[List of California area codes]] *[[List of North American Numbering Plan area codes]] ==References== {{Reflist}} ==External links== {{NANPA area code map|Map=CA}} <!-- Placing templates --> {{Area code box | State = CA | This = area code 805/820 | N = [[area code 661|661]], [[area code 831|831]] | S = [[area codes 310 and 424|310/424]], Pacific Ocean | E = [[area code 559|559]], [[area code 661|661]], [[area codes 818 and 747|818/747]] | W = [[Pacific Ocean]], [[area code 808|808]] |S1=HI}} <!-- Other templates --> {{coord|34.6|-120.2|region:US-CA_type:adm2nd_dim:400km|display=title}} [[Category:Area codes in California|805 820]] [[Category:Area codes in the United States|805 820]] [[Category:Monterey County, California]] [[Category:Santa Barbara County, California]] [[Category:San Luis Obispo County, California]] [[Category:Ventura County, California]]
