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.

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.
