Feature Answer

What is Area Code 310?

Area code 310 is a North American telephone area code assigned to the Los Angeles Westside, California. Created in 1991 when 213 was split to relieve number exhaustion, 310 has become the prestige area code of the LA Westside. It serves Beverly Hills, Santa Monica, Malibu, West Hollywood, Westwood, Culver City, Manhattan Beach, Hermosa Beach, Redondo Beach, San Pedro, and other beach and Westside communities. It is a local (non-toll-free) area code in the Pacific Time Zone.

When 213 was split in 1991, 310 was carved out to cover everything west and south of downtown LA — from West Hollywood and Beverly Hills down to the South Bay beaches. Within a decade it had become a luxury and entertainment-industry signal: production companies, talent agencies, and high-end real estate firms all clustered around 310 numbers. Overlay 424 was added in 2006 when 310 numbers ran low. Despite the overlay, 310 remains the more prestigious of the two codes — a status signal in Hollywood, Beverly Hills, and Malibu.

WHY VERIFIED MATTERS

Why aren't 310 numbers enough on their own?

Even a Westside 310 code can hit voicemail if it's not registered. LA customers are 3.6x more likely to answer a 310 call that shows up as a verified business than one displaying as just digits.

Verified 310 = 3.6x more pickups

Stand out from spam. A Brilo 310 number comes with a verified business profile, AI-powered calling, and live transcripts — so you're never mistaken for a robocall.
