, and includes several Southeast LA communities, such as Bell and Huntington Park. The area codes designated separate NPAs starting in 1998, when 323 was added, but were combined in an overlay plan into a single NPA in 2017. Previously, just downtown Los Angeles and immediately adjoining neighborhoods were served by area code 213, and the rest of central Los Angeles used area 323. Area code 213 is one of the original area codes created with the NANP in 1947, and was split five times over the decades.

History

In 1947, when the American Telephone and Telegraph Company (AT&T) devised the initial form of the North American Numbering Plan, the state of California was divided into three numbering plan areas: 213,

415 __NOTOC__ Year 415 ( CDXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Honorius and Theodosius (or, less frequently, year 1168 '' ...

, and 916, for the southern, central, and northern parts of the state, respectively. The area served by 213 extended from Mexican border to the Central Coast. In 1950, the boundary between 213 and 415 was realigned toward the north, requiring the southern portion of the Central Valley, including Bakersfield, to change from area code 415 to 213. As a result of southern California's rapid expansion of telephone service during the second half of the 20th century, area code 213 was split five times in the period from 1951 to 1998. In the 21st century area code overlays have become more practical.

1951–1998: Area code splits

The first split became necessary in 1951, when most of the southern and eastern portion, including

and most of Orange County, was assigned area code 714. In 1957, 213 was restricted to

received area code 818, thus making Los Angeles one of the first major cities in the US to be split into two numbering plan areas—New York City experienced this later in the same year. In 1991, West Los Angeles and the South Bay were assigned area code 310. In 1998, the Los Angeles NPA was divided once more, to create area code 323. Area code 213 was kept by 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), ''5'' (Boyle Heights/East Los Angeles), ''6'' (Watts/Vernon/South Gate), ''8'' (South Los Angeles), ''9'' (Hyde Park/Athens), ''11'' (West Adams/Jefferson Park), ''12'' (Leimert Park/Baldwin Hills), ''13'' (Hancock Park/Fairfax District) and ''14'' (Hollywood/Hollywood Hills) switched to area code 323. This split made 213 one of the geographically smallest numbering plan areas in the nation, covering only Downtown Los Angeles and its immediately adjoining neighborhoods, such as Chinatown. Completely surrounding 213, 323 included most of the remainder of central Los Angeles, including Hollywood, as well as several neighboring cities, including Bell, Huntington Park and Montebello.

Since 2017: Overlay codes

Despite Southern California's continued growth and the proliferation of cell phones and pagers, 213 was not projected to exhaust until 2050. In contrast, 323 was projected to exhaust in 2017. Since 213 still had an abundance of numbers available, the California Public Utilities Commission approved a plan that erased the boundaries between both area codes, converting the area to an overlay plan for all of central Los Angeles. Since this change went into full effect on July 8, 2017, telephone companies have been able to assign any available 213 numbers in the former 323 area and vice versa, and customers with 213 or 323 phone numbers have been required to dial the area code for all calls within the area. This change returned 213 to some areas that had used it for more than half a century prior to 1998.
