Area codes 714 and 657 are telephone area codes in the North American Numbering Plan for the southern part of the U.S. state of California. The numbering plan area comprises northern Orange County, a portion of Los Angeles County, and the Sleepy Hollow and Carbon Canyon areas of Chino Hills in San Bernardino County. Area code 714 was assigned to a part of numbering plan area 213 in 1951, and 657 was added in 2008 to form an overlay complex.
In 1947, when 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: 213, 415, and 916, for the southern, central, and northern parts of the state, respectively. [1] The area served by 213 extended from Mexican border to the Central Coast. Starting in the 1950s, Southern California experienced rapid expansion of telephone service, requiring area code 213 to be split five times by 1998. The first split became necessary in 1951, when most of the southern and eastern portion, including San Diego and most of Orange County, was assigned area code 714 in a flash cut, without a permissive dialing period[ further explanation needed ]. This 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 442/760, 619, 858, 909, and 951). Despite Southern California's growth in the second half of the 20th century, this configuration remained in place for 31 years.
On January 1, 1982, most of the southern and eastern portion, centered around San Diego and the desert areas, became area code 619. In 1992, eastern Los Angeles and the Inland Empire became area code 909. On April 18, 1998, the southern cities of Orange County were split from 714, creating area code 949.
By 2007, 714 was running out of telephone numbers due to Southern California's continued growth and the proliferation of mobile telephones. As a solution, area code 657 was overlaid onto the 714 territory on September 23, 2008. [2]
The service area includes northern and western Orange County, except for portions of La Habra and all of Seal Beach, Los Alamitos, the far northwestern portion of Brea, and the western portions of La Palma, 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, the primary telephone provider for Long Beach (this territory has since become part of Verizon, and now Frontier Communications).
Today, five cities "straddle" the 657/714 and 949 area codes: Costa Mesa, Irvine, Santa Ana, Tustin, and Newport Beach.
Cities in the numbering plan area include Tustin, Placentia, Anaheim, Buena Park, Costa Mesa (unique because it is split between the 714/657 and 949 area codes, at Wilson Street and along Newport Boulevard), Cypress, Fountain Valley, Fullerton, Orange, Garden Grove, Santa Ana, Villa Park, Yorba Linda, portions of La Habra, and most of Brea and Huntington Beach.
Area codes 213 and 323 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. They are assigned in an overlay complex to a numbering plan area (NPA) that comprises, roughly, the area of downtown Los Angeles City, as well as several southeast Los Angeles County cities, such as Bell and Huntington Park. Area code 213 was one of the original North American area codes of 1947 and 323 was created in an area code split of 213 in 1998. This was the fifth split of 213 and left it serving only downtown Los Angeles and immediately adjoining neighborhoods. In 2017, the two NPAs were recombined in the overlay.
Area codes 760 and 442 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. These area codes serve an overlay complex that comprises much of the southeastern and southernmost portions of California. It includes Imperial, Inyo, and Mono counties, as well as portions of North County San Diego, Riverside, San Bernardino, Los Angeles and Kern counties. Area code 760 was created on March 22, 1997 in a split of area code 619. Area code 442 was added to the same area on November 21, 2009.
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.
Area code 701 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. State of North Dakota. It is one of the 86 original North American area codes created by AT&T in 1947, and continues to be the only area code in North Dakota, one of eleven states with only one area code.
Area codes 310 and 424 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. The numbering plan area includes the West Los Angeles and South Bay areas of Los Angeles County, a small portion of Ventura County, and Santa Catalina Island, which is located 26 miles (42 km) south.
Area codes 909 and 840 are telephone area codes in the North American Numbering Plan for the far-eastern part of Los Angeles County and southwestern San Bernardino County in the U.S. state of California. Area code 909 was created on November 14, 1992, in an area code split of 909, and 840 was added to the numbering plan area to form an overlay complex effective February 23, 2021.
Area code 949 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of California in southern Orange County. The area code was assigned on April 18, 1998, to a numbering plan area that resulted from a boundary change of area code 714 to exclude the southern cities of Orange County.
Area codes 619 and 858 are telephone area codes in the North American Numbering Plan (NANP) for most of San Diego County in the U.S. state of California. Area code 619 was created by a split of area code 714 in 1982. In 1999, a part of the 619 numbering plan area was assigned area code 858 in northwest San Diego County. In 2019, the area code boundary between 619 and 858 was eliminated, creating an overlay complex with the two area codes.
Area code 562 is a California telephone area code that was split from area code 310 on January 25, 1997. It is the area code for much of southeastern Los Angeles County, including Long Beach, and parts of northern Orange County.
Area code 626 is a telephone area code in the North American Numbering Plan for most of the San Gabriel Valley in the U.S. state of California. The numbering plan area also comprises nearby areas in the northeastern portion of Los Angeles County, California, including Arcadia, Monrovia, El Monte, most of Pasadena and West Covina. The numbering plan area was split from that of area code 818 on June 14, 1997.
Area code 951 is a telephone area code in the North American Numbering Plan for western Riverside County in the southern part of the U.S. state of California. It was assigned in 2004 to a new numbering plan area that was created by an area code split of area code 909.

La Habra–Fullerton–Yorba Linda Line was a Pacific Electric interurban line which traveled between Los Angeles and Yorba Linda. Passenger services ran between 1911 and 1938. Initial plans were for the route to continue further east to form a second main line between Los Angeles and San Bernardino, though these would go unfulfilled. After passenger service ended, much of the route was retained for freight service, eventually becoming the Union Pacific La Habra Subdivision.
The Municipal Water District of Orange County, commonly known by the acronym MWDOC, is a wholesale water provider, water resource development and planning agency., water-centric information, education, emergency planning, and conservation resource hub for nearly 3.2 millionOrange County, California residents, and businesses. Local water supply sources meet only about half of the region's total water needs. To fulfill the remaining demand, MWDOC buys imported water from the California State Water Project in northern California and the Colorado River through the Metropolitan Water District of Southern California (Metropolitan). MWDOC delivers water to its 27 member agencies - made up of both water districts and city water departments - who then, in turn, provide retail water service to the public.
