Area Code 310 is a telephone area code in California, primarily serving the western part of Los Angeles County. It was created in 1991 when it was split from the 213 area code. The area code covers popular locations such as Santa Monica, Beverly Hills, and Malibu. In 2006, the area code was overlaid with the new area code 424 to accommodate the growing demand for phone numbers. Area Code 310 is known for its association with the entertainment industry, as it includes many neighborhoods where celebrities and film studios are located.
