About the 310 area code

The 310 area code is an integral part of California's telecommunications network, serving the western and southwestern portions of Los Angeles County. Establishment and Geographic Coverage: The 310 area code was created on November 2, 1991, as a split from the 213 area code. This division was implemented to accommodate the increasing demand for new telephone numbers in the rapidly growing region. The 310 area code covers the western parts of Los Angeles County, including cities like Beverly Hills, Santa Monica, and Torrance, as well as portions of the southwestern Los Angeles area. Economic and Cultural Significance: The region served by the 310 area code is economically and culturally diverse, encompassing major business districts, affluent residential areas, and iconic cultural landmarks. The area is home to the entertainment industry in Hollywood, prestigious universities, and numerous tourist attractions, playing a significant role in California's economy and cultural identity. Introduction of Overlay Area Code and Ten-Digit Dialing: To address the need for more telephone numbers, the 424 area code was introduced as an overlay to the 310 area code in 2006. This overlay required the implementation of ten-digit dialing (area code + phone number) for all local calls within the region. The introduction of the 424 overlay and the shift to ten-digit dialing reflect the ongoing growth and technological development of the Los Angeles area. These facts about the 310 area code underscore its crucial role in supporting the dynamic telecommunications needs of western and southwestern Los Angeles County. By accommodating the region's growing and diverse communication requirements, the 310 area code, along with its overlay 424, ensures efficient connectivity for one of California's most populous and influential regions.
