The location served by way of 213 prolonged from Mexican border to the Central Coast. In 1950, the boundary among 213 and 415 was realigned towards the north, requiring the southern portion of the Central Valley, such as Bakersfield, to change from area code 415 to 213.

As a result of southern California's fast enlargement of cellphone provider at some stage in the second half of the twentieth century, location code 213 become cut up 5 times within the period from 1951 to 1998. In the twenty first century place code overlays have come to be extra practical.

1951–1998: Area code splits

The first cut up became necessary in 1951, when most of the southern and jap component, which include San Diego and maximum of Orange County, become assigned location code 714. In 1957, 213 became restrained to Los Angeles County, with most of the northern and western portions receiving location code 805. This configuration changed into stable for nearly 3 a long time, until 1984, while the San Fernando Valley and the San Gabriel Valley obtained area code 818, for this reason making Los Angeles one of the first essential cities in the US to be break up into two numbering plan regions—New York City skilled this later inside the same year. In 1991, West Los Angeles and the South Bay have been assigned place code 310.[1]

In 1998, the Los Angeles NPA became divided once more, to create area code 323.[2] Area code 213 become stored with the aid of Los Angeles exchanges 1 (Downtown/Echo Park), 7 (South Park/Exposition Park) and 10 (Westlake/Koreatown), while exchanges 2 (Silverlake/Los Feliz), 3 (Eagle Rock/Highland Park), 4 (El Sereno/Lincoln Heights), five (Boyle Heights/East Los Angeles), 6 (Watts/Vernon/South Gate), 8 (South Los Angeles), 9 (Hyde Park/Athens), eleven (West Adams/Jefferson Park), 12 (Leimert Park/1st earl baldwin of bewdley Hills), 13 (Hancock Park/Fairfax District) and 14 (Hollywood/Hollywood Hills) switched to place code 323. This cut up made 213 one of the geographically smallest numbering plan areas in the nation, covering most effective Downtown Los Angeles and its right now adjoining neighborhoods, including Chinatown. Completely surrounding 213, 323 covered most of the remainder of valuable Los Angeles, such as Hollywood, as well as numerous neighboring towns, consisting of Bell, Huntington Park and Montebello.[3]

Since 2017: Overlay codes

Despite Southern California's continued growth and the proliferation of cell phones and pagers, 213 changed into not projected to exhaust till 2050. In evaluation, 323 turned into projected to exhaust in 2017.[3] Since 213 nonetheless had an abundance of numbers available, the California Public Utilities Commission accredited a plan that erased the limits among each location codes, converting the place to an overlay plan for all of important Los Angeles. Since this change went into complete effect on July eight, 2017, smartphone groups had been able to assign any available 213 numbers within the former 323 place and vice versa, and customers with 213 or 323 telephone numbers have been required to dial the place code for all calls within the region.[4][5] This trade again 213 to some areas that had used it for more than half a century prior to 1998.[2] areacodehelper
