About the 310 region
310 covers West LA in California, including Santa Monica, Beverly Hills, Culver City, Torrance and Malibu. The code has been in service since 1991.
As the West LA region grew, 310 ran low on available numbers, so 424 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
Split of 213; 1997: split to create 562; 2006: overlaid by 424.
