[Abstract not available for the category]
North American Area code 909 is a California telephone area code which was split from area code 714 on November 14 ,1992. Western Riverside County was split off from 909 into area code 951 on July 17, 2004. 909 still covers small portions of Corona, Riverside, and Moreno Valley which are in Riverside County.
The 909 area code now covers far eastern Los Angeles County and southwestern San Bernardino County. It contains cities such as: Colton, San Bernardino, Ontario, Fontana, Chino, and Pomona.
The cost of living in "the 909" is generally less expensive than many parts of Los Angeles and Orange counties. Thus, many people live in "the 909" and commute westward to Orange and Los Angeles countieshttp://www.cityoftemecula.org/Temecula/Businesses/Demographics/HusingReport/Husing2005Section9.htm. Under the traditional NANPA plan, 909 would be considered the "worst" area coded for pulse dialers, because of the length of time to send the pulse signal, in contrast to area codes such as 212 or 213.
North American area code 213 is a California telephone area code which was one of the first three area codes created in California in October 1947. It originally contained all of Southern California and was generally associated with Los Angeles.
Over the years it has been subdivided a number of times and is now completely surrounded by the 323 area code, it contains only downtown Los Angeles and its immediate environs. The subdivisions to date have been: *area code 714 (a flash-cut sometime during 1951) *area code 805 (a flash-cut sometime during 1957) *area code 619 (split from 714 on November 5 ,1982) *area code 818 (January 7 ,1984) *area code 310 (November 2, 1991) *area code 909 (split from 714 on November 14 ,1992) *area code 562 (split from 310 on January 25 ,1997) *area code 760 (split from 619 on March 22 ,1997) *area code 626 (split from 818 on June 14 ,1997) *area code 949 (split from 714 on April 18 ,1998) *area code 323 (June 13 ,1998) *area code 661 (split from 805 on February 13 ,1999) *area code 858 (split from 619 on June 12 ,1999) *area code 951 (split from 909 on July 17 ,2004) *area code 424 (overlay of 310 created on August 26 ,2006) *area code 657 (overlay of 714 created on September 20 ,2007)
This area code includes East Compton, part of Los Angeles, and Willowbrook.
Telephone area code 626 covers most of the San Gabriel Valley and nearby areas in the northeastern portion of Los Angeles County, California, including Arcadia, Monrovia, El Monte, most of Pasadena and West Covina. The area code was created in a split from 818 on June 14, 1997.
Area code 747 and Area code 818 are California telephone area codes consisting largely of the San Fernando Valley of Los Angeles, California. They cover roughly two million people.
North American area code 619 is a California telephone area code which was split from area code 714 on November 5, 1982.http://www.areacode-info.com/!history/1980s.htm This area code currently covers the southern half of the city of San Diego and its eastern and southern suburbs.
Before it was split to form area code 760, 619 was the area code for a large geographical area that spanned all of San Diego county as well as desert counties along the eastern border of the state from the Mexican border almost to Lake Tahoe. Area code 760 was designated as the outer northern suburbs of San Diego (such as Oceanside, Vista, Fallbrook, San Marcos and Escondido), as well as the county's eastern mountain areas and all portions of the old area code lying outside San Bernardino County.
Area code 858, which covers the northern half of the city and the inner northern suburbs, was a result of a later split. This area includes Del Mar and La Jolla, and Miramar MCAS.
North American area code 858 is located in San Diego County, California and covers the inner northern suburbs of San Diego, California and the northern half of the city proper, including the areas of Del Mar, Poway, La Jolla, Pacific Beach, Clairemont, and MCAS Miramar. This area code split from the 619 area code in 1999.
The outer northern suburbs of San Diego and the mountainous areas to the east (such as Ramona, Santa Ysabel, Warner Springs and Julian) are serviced by area code 760, which itself was a result of an earlier split of area code 619.
North American area code 951 is a California telephone area code which covers western Riverside County and was split off from the 909 area code in 2004. It covers Beaumont, Corona, Canyon Lake, Riverside, Temescal Canyon, Woodcrest, Arlington, Mira Loma, Moreno Valley, Perris, Sun City, Lake Elsinore, Murrieta, Temecula, Hemet, Lakeview, Nuevo, Norco, Banning, Eastvale, Quail Valley and Idyllwild.
Area code 415 is the telephone area code for San Francisco, as well as portions of neighboring Brisbane and Daly City; and Marin County (across the Golden Gate Bridge to the north), in the state of California, USA.
North American area code 323 is a state of California telephone area code which covers, roughly, the area of central Los Angeles (excluding Downtown Los Angeles and immediately adjoining neighborhoods such as Koreatown, Echo Park, and Chinatown). 323 also includes Hollywood. The territory now covered by 323 was covered by area code 213 until it was created as an area code split on June 13, 1998.
North American area code 408 is a telephone area code in California that includes Gilroy, Morgan Hill, Saratoga, Los Gatos, Monte Sereno, Milpitas, Sunnyvale, Santa Clara, Cupertino, and San Jose. It was created in a 1959 split from area code 415 in a flash-cut with no permissive dialing period. On July 11, 1998, it was split again, with area code 831 being created for the counties of Santa Cruz, Monterey, and San Benito.
Area code 949 is an area code in California that is contained mostly within the southern areas of Orange County. It also includes a small adjacent area of northwest San Diego County, specifically parts of Marine Corps Base Camp Pendleton and San Onofre State Park. It includes such cities as Newport Beach, Lake Forest, Portola Hills, Coto de Caza, Dove Canyon, Aliso Viejo, Trabuco Canyon, Capistrano Beach, Corona Del Mar, Laguna Niguel, Laguna Hills, Laguna Woods, Monarch Bay, Newport Coast, Irvine, Foothill Ranch, Robinson Ranch, Mission Viejo, San Juan Capistrano, Rancho Santa Margarita, Ladera Ranch, Dana Point, Laguna Beach, and San Clemente. Costa Mesa is shared between the 949 and 714 area codes, being split at Wilson Street and along Newport Boulevard.
North American area code 530 is a California telephone area code that covers Auburn, Chico, Colfax, Davis, Grass Valley, Marysville, Oroville, Placerville, Redding, Red Bluff, Susanville, Truckee, Woodland and Yuba City.
530 was created on Nov. 1, 1997, when it was split from the 916 area code. On the same day, the Dixon exchange was moved from Sacramento LATA to San Francisco LATA and from the 916 area code to 707.
California's area code 831 is a North American area code which covers Salinas, Hollister, Monterey, Santa Cruz and the northern Central Coast. It was created in a split from area code 408 on July 11, 1998.
California area code 661 covers the majority of California's Kern County, as well as part of Los Angeles County and Tulare County. It was split from area code 805 on February 13, 1999.
Principal cities in the 661 area code are: *Bakersfield *Palmdale *Santa Clarita *Lancaster
North American area code 510 is a California telephone area code which covers most eastern Bay Area cities in Alameda County, including the city of Oakland (except Dublin, Livermore, Pleasanton, and Sunol), and parts of Contra Costa County. The area code was created from a split of area code 415 on September 2, 1991.http://www.nanpa.com/pdf/old_pl/IL%2090-06-023.pdf The area code is the origin of the urban slang "the nickel and dime", used by some to refer to the East Bay.
In the North American Numbering Plan (NANP), area code 925 is an area code that covers the inland portions of the East Bay counties of Alameda and Contra Costa in central California.
It was originally part of the 415 area code, one of the first three area codes created in California in 1947, which originally covered all of central California. In 1991 the 510 area code was created to encompass most of the Oakland Metropolitan Statistical Area (MSA). The 925 area code was created March 14, 1998 when the 510 area code was itself split along the natural border of the East Bay Hills. The number was formed by taking 415 and adding 510 which equals 925. It currently includes most of Contra Costa County and the eastern portion of Alameda County and is wholly contained within the Oakland MSA.
The area code includes all of Contra Costa County except the western part (El Cerrito to Crockett), and southwestern Alameda County (Dublin, Pleasanton, Livermore, Sunol, and unincorporated areas surrounding those communities).
North American area code 650 is a California telephone area code which includes most of San Mateo County (except the northernmost portion) and the extreme northwestern portion of Santa Clara County including Palo Alto, Mountain View, and Los Altos.
The 650 area was created by a split from area code 415. A six month "permissive dialing" period when either area code would work began August 2, 1997. Mandatory dialing of the new area code started on January 31, 1998.
North American area code 916 is a state of California telephone area code which was one of the first three original area codes established in California in October, 1947. It covered the far north portion of the state. It was split in a flash-cut sometime during 1958, creating area code 209. 916 was again split on November 1, 1997 creating Area code 530. Today, 916 covers only the state capital of California and its immediate area.
Area code 559 is an area code in the state of California that was created on November 14, 1998, when the southern half of the area code 209 (in service since 1958) reached full capacity. Like many other regions that had experienced area code changes during the area code boom of the 1990's, both 559 and 209 were in the early planning stages of relief, potentially creating the need for introduction of further new area codes. Yet by 2002, number blocking was being enforced in the 209 and 559 area codes. Instead of handing out numbers in blocks of 10,000 to private companies (as had been normal practice since the beginning of the NANP in 1947), only 1,000 numbers would be handed out at a time. For example, instead of granting Pacific Bell all numbers (559) 330-xxxx, only numbers (559) 330-0xxx, or (559) 330-1xxx or (559) 330-2xxx, and so on, would be granted.
North American area codes 657 and 714 are California telephone area codes which encompass northern Orange County, a portion of Los Angeles County, and portions of Chino Hills in San Bernardino County. Area code 714 was split from area code 213 as a flash-cut sometime during 1951; area code 657 went into service as an overlay to 714 on September 23, 2008.http://www.nanpa.com/pdf/PL_368.pdf
Cities in the 657 and 714 area codes include Tustin, Placentia, Anaheim, Buena Park, Cypress, Fountain Valley, California, Fullerton, Orange, Garden Grove, Santa Ana, Yorba Linda, Brea and most of Huntington Beach.
The 714 area code once included most of Southern California, generally south and east of Los Angeles, extending to the Arizona and Nevada state lines to the east, and south as far as the Mexican border (what is now area codes 619, 760 and 909, 951 and 858). It experienced several splits, the first of which moved San Diego County, Imperial County and the desert areas of Riverside and San Bernardino Counties into area code 619 on November 6, 1982. It was again split, moving eastern Los Angeles and the Inland Empire areas of San Bernardino and Riverside Counties into area code 909 on November 14, 1992. On April 18, 1998 the southern cities of Orange County were split from 714, creating area code 949.
The two area codes now cover northern and western Orange County (except for La Habra, Los Alamitos, Seal Beach and the western portions of La Palma and Huntington Beach, which have always been in the same area code as Long Beach—currently the 562 area code). This is probably because at the time those splits first occurred, while most cities in Southern California were provided primary local telephone service from what was then Pacific Bell (now AT&T), the cities listed above were served by GTE (now Verizon) which is the primary telephone provider for Long Beach. 657/714 also contains the Carbon Canyon area of Chino Hills which is in San Bernardino County.
Today, four cities "straddle" the 657/714 and 949 area codes: Costa Mesa, Irvine, Santa Ana, and Tustin.
North American area code 442 is a scheduled telephone area code to be overlaid onto 760. Callers may begin dialing 442 in May 2009; 442 becomes mandatory in November 2009.
The original plan for 442 was a split from 760; the portion of the area code in San Diego County would have become 442, while the rest of the area code would have remained 760. This plan, when announced, was met with protest in the affected areas. Many of the protesters organized through the website Keep760.org, which supported an overlay rather than a split. In a rare move, the California Public Utilities Commission agreed to reconsider their decision, and on October 16, 2008, the original plan was scrapped in favor of an overlay.
According to the schedule announced by the CPUC, permissive dialing begins on May 2, 2009; mandatory dialing begins October 24; and the overlay becomes effective on November 21.
North American telephone area codes 310 and 424 are the California telephone area code which are roughly coterminous with the West Los Angeles and South Bay areas of Los Angeles County, including offshore Catalina Island, located 40 km (26 mi.) south of the mainland portion of Los Angeles County. Area code 310 was split from Area code 213 on November 2, 1991; The 424 area code overlay of 310 became effective on July 26, 2006. Area code 213, which at its inception covered all of Southern California, is now reserved exclusively for the area of Downtown Los Angeles.
Area code 424 is the first non-mobile area code overlay in Southern California. Because of this, dialers in the 310 area code are no longer able to dial a 7-digit number even if they are dialing another phone number in the same area code. Until the overlay of area codes 657 and 714 became active in 2008, the 310-424 complex was the only area code overlay in the entire state of California, despite California having more area codes than any other state.
"The 310" is often used as shorthand for the West Side of Los Angeles and the South Bay region south of LAX. Unlike Manhattan's 646 overlay, when 310 was introduced it immediately became more desirable than the older 213 because of its connection with the affluence of Beverly Hills, Malibu, Santa Monica, and other parts of West Los Angeles.
