About the 310 Area Code

Greater Los Angeles is served by the 310 area code across the Westside, the South Bay, and the coastal communities that run along Santa Monica Bay and southward toward the Palos Verdes peninsula. The 310 designation has been associated with this region since the early 1990s, when it was split from the original 213 numbering as the metro's number demand outgrew a single code. Within its footprint sit Beverly Hills, Santa Monica, Culver City, Inglewood, Torrance, Long Beach's western edge, and a stretch of the city of Los Angeles that includes the airport, the entertainment-industry studios, and the research and technology corridor that has grown up around them.

Other California cities — Anaheim, Bakersfield, Chico, Concord, and many more — recur in the directory's records tied to 310 numbers. None of those are inside the 310 footprint. The pattern reflects high mobility within California and the way numbers and their associated public records flow across regions through porting and address linkage. The directory documents 715 distinct prefixes within 310 in detail, which represents our working coverage; the live prefix total carried by the code is larger.

The Los Angeles housing market dominates the demographic story: typical home values within the broader city run several times the US median, a function of long-standing supply constraints and concentrated coastal demand. Household income tracks above the national figure, the population is among the largest of any US city, and the median age is several years younger than the country at large.
