323 area code summary
The 323 area code is a significant part of California's telecommunication landscape.
Origins and Service Date: Area code 323 was assigned for use in California on May 19, 1997, and officially went into service on June 13, 1998. This area code was created following a split or overlay from the existing 213 area code. Geographic Coverage: It covers a substantial area within California, encompassing 29 cities. Notable among these are Los Angeles, Long Beach, Glendale, Pasadena, and El Monte. In terms of county coverage, it extends over the entirety of Los Angeles County. General Purpose Code with Overlap: Area code 323 is classified as a General Purpose Code. This means it is used for regular telephone services rather than being reserved for specific functions like customer service lines. Importantly, the 323 service area overlaps with the 213 area code. This overlap indicates a shared geographical region served by both area codes, which is not uncommon in densely populated areas.
In conclusion, the 323 area code is a vital component of California's telecommunication system, especially within the Los Angeles County region. Its establishment as a split from the 213 area code and its coverage of multiple key cities make it an essential part of the state's communication infrastructure.
