310 numbers by area

Each city and district in the 310 area has its own mix of businesses, from film studios in Culver City to aerospace in El Segundo and shipping in San Pedro, and the numbers that work best follow it. No 310 number belongs to a particular city or area. These pages describe the businesses in each part of 310, not where a number has to be used: on a mobile phone or an internet phone line, a 310 number works anywhere.

310 runs along the coast from Malibu to the Palos Verdes Peninsula and San Pedro, and inland across the Westside and the South Bay, so those are the places listed here. Downtown Los Angeles and Hollywood are on 213 and 323, and the San Fernando Valley is on 818 and 747, but a business there can still use a 310 number: it rings wherever your carrier sends it.
