The Westside Corridor

Area code 310 was introduced on November 2, 1991, as a split from the 213 area code, created to serve the rapidly growing western and coastal regions of Los Angeles County. It covers the communities of the Westside — from Santa Monica and Malibu along the Pacific coast, through Brentwood, Pacific Palisades, Culver City, and Inglewood, to Beverly Hills and West Hollywood, and south through the South Bay communities of Manhattan Beach, Redondo Beach, Torrance, and Rancho Palos Verdes.

The 310 is one of the most recognizable and sought-after area codes in the United States, widely associated with affluence, the entertainment industry, and the distinctive culture of the California coast. Its overlay, area code 424, was introduced in 2006 to address demand for new numbers.

Where Industries Converge

The 310 geography is defined by the intersection of industries that generate some of the most complex and high-value legal work in the country: entertainment, technology, real estate, finance, and the personal legal needs of a disproportionate concentration of high-net-worth individuals and executives.

California law governs employment relationships throughout the 310, with some of the most employee-protective statutes in the nation — a framework that shapes every executive compensation negotiation, equity arrangement, and separation agreement arising in the region. The entertainment industry adds a further layer of specialized guild, residual, and intellectual property law found nowhere else.
