What Is the 310 Area Code?

The 310 area code is a telephone area code for western and southern Los Angeles County, California. It was created in 1984 when the original 213 area code — which once covered all of Southern California — was split to accommodate the region’s explosive population and business growth. Today, 310 covers the Westside corridor from Malibu through Santa Monica, Beverly Hills, Culver City, and down through El Segundo, Manhattan Beach, and Torrance.

Key facts about 310:

• State: California
• County: Los Angeles County (west and south)
• Time Zone: Pacific Time (PT) — UTC-8 / UTC-7 DST
• Overlay: 424 area code (introduced 2006)
• Introduced: 1984
• Cities covered: Beverly Hills, Santa Monica, Culver City, El Segundo, Hawthorne, Inglewood, Malibu, Manhattan Beach, Redondo Beach, Torrance, Venice, Marina del Rey

Both 310 and 424 serve the same geographic area — they are an overlay pair. A west or south LA phone number may carry either prefix.

Where Is the 310 Area Code Located?

The 310 area code is located in western and southern Los Angeles County, California — stretching from Malibu on the coast to Torrance in the south and Beverly Hills in the east.

310 vs 424: What’s the Difference?

Both 310 and 424 serve the same western and southern Los Angeles County region. The 310 code came first — it was created in 1984 when Southern California split the original 213 code due to rapid growth. By 2006, the demand for new west LA phone numbers had exhausted available 310 combinations, and the 424 overlay was introduced to provide additional capacity for the identical geographic area.

There is no difference in coverage area between 310 and 424 — both codes reach the same cities and neighborhoods in west and south LA County. 310 carries strong name recognition due to its longer history and association with Beverly Hills and Santa Monica.

Why West LA Businesses Use 310 VoIP Numbers

West Los Angeles is built on entertainment, technology, aerospace, luxury real estate, and healthcare. The Westside corridor contains some of the highest concentrations of media companies, venture-backed startups, defense contractors, and high-net-worth consumers in the country.

For businesses here — and for companies targeting Westside LA clients — a local 310 number delivers immediate credibility:

• Outbound answer rates are 400% higher with a local area code vs. unknown or toll-free numbers
• 310 carries prestige — Beverly Hills, Santa Monica, and Malibu are synonymous with the 310 prefix; it signals established Westside presence
• High-value clientele in luxury real estate, entertainment, and finance expect to see a local number before answering

West LA-Specific Considerations

Silicon Beach: Cloud VoIP for Fast-Growing Tech Teams

The stretch from Venice to Playa Vista to Santa Monica is home to one of the densest concentrations of tech companies outside San Francisco — Snapchat, Google, Amazon, Hulu, and hundreds of startups. These teams scale fast: 10 people today, 100 in a year. Traditional PBX systems require hardware procurement, installation, and months of lead time for each expansion. VestaCall adds users in minutes at $19/user/month — no hardware, no installation, no contracts. When your Series A closes and you triple headcount, your phone system keeps up without a second thought.

Entertainment: Sony, Amazon Studios, and the Culver City Corridor

Culver City hosts Sony Pictures Entertainment and Amazon Studios. The broader west LA market is saturated with production companies, talent agencies, post-production facilities, and entertainment law firms. These businesses have specific requirements: call recording for deal negotiations and talent agreements, multi-party conferencing for production coordination, and CRM logging to track every client interaction. VestaCall includes all of this at no additional charge — no per-feature add-ons.

Aerospace: Boeing, SpaceX, and the El Segundo Defense Corridor

El Segundo is one of the most concentrated aerospace and defense corridors in the United States — Boeing, SpaceX, Northrop Grumman, Raytheon, and L3Harris all have significant operations here. Supplier networks and contractor firms in the 310 footprint need reliable, secure communications with redundant failover. VestaCall’s 99.999% uptime SLA and automatic mobile failover ensure that a power outage or network disruption at one facility does not interrupt business-critical communications.

Luxury Real Estate: Beverly Hills and Malibu Client Credibility

In Beverly Hills and Malibu, the phone number you call from matters. High-net-worth buyers and sellers are conditioned to screen unknown or out-of-area calls — they simply do not answer. A 310 caller ID from a real estate agent or property manager signals local, established presence and gets picked up. VestaCall agents can use their personal mobile device while displaying a 310 business number — keeping their personal number private while maximizing client answer rates.
