Extended information

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.
