Silicon Beach — the tech corridor across Santa Monica, Venice, and Playa Vista — houses Google, Snapchat, and Hulu. The 310 area code identifies the Westside and South Bay of Los Angeles, where entertainment powerhouses, aerospace giants, and one of America's fastest-growing tech ecosystems converge. If you're building a presence in the LA market, a 310 number immediately signals local credibility.

Where Does the 310 Code Cover?
The 310 area code spans a wide portion of Los Angeles County, running from Beverly Hills and Bel Air to the beaches of Malibu and the harbor communities of the South Bay.
Westside Los Angeles
Beverly Hills is synonymous with luxury retail and entertainment. Santa Monica anchors Silicon Beach, housing major tech offices. Culver City is a production hub — Sony Pictures, Apple, Amazon, and HBO all have significant presences there. Venice hosts Google's Los Angeles campus, and Westwood is home to UCLA and major corporate offices.
South Bay
El Segundo is a major aerospace corridor, with Lockheed Martin, Northrop Grumman, and Raytheon operating there. Hawthorne is home to SpaceX headquarters. Torrance carries a diverse economy with Honda's US headquarters as a flagship employer. Redondo Beach, Manhattan Beach, and Hermosa Beach form the Beach Cities. Inglewood is undergoing revitalization anchored by SoFi Stadium, home to the LA Rams and Chargers.
Other Notable Coverage
Malibu extends the 310 footprint 27 miles along the Pacific Coast Highway. Santa Catalina Island, 25 miles offshore, also falls within the 310 coverage zone.
History of the 310 Area Code
The 310 area code was created on November 2, 1991, when the original 213 area code — covering all of Southern California since 1947 — could no longer meet demand. The State of California remains the country's most active state for new area code allocations, driven by its dominant technology and entertainment economy.
1991 — Creation: Area code 310 split from 213, taking the Westside, South Bay, and coastal communities. The 213 retained Downtown Los Angeles.
1997 — The 562 Split: The southeast portion of LA County — Long Beach, Downey, and surrounding communities — was reassigned to the new 562 area code, shrinking the 310 area code to its current boundaries.
2006 — The 424 Overlay: On July 26, 2006, the 424 area code was added as an overlay — the first overlay in California — introducing mandatory 10-digit dialing for all local calls.
310 Area Code Time Zone
This region operates entirely within the Pacific Time Zone (PT). Area code 310 and the 424 area code share the same Pacific Time zone, as 424 is an overlay for the same territory.
- Pacific Standard Time (PST): UTC−8 — early November to mid-March
- Pacific Daylight Time (PDT): UTC−7 — mid-March to early November
Practical Calling Considerations
Eastern Time is 3 hours ahead of Pacific Time — a 9 AM PT call reaches New York at noon ET, ideal for cross-coast coordination. The best window for business calls to area code 310 is 9 AM – 5 PM PT.
Is a 310 Area Code Call a Scam?
The 310 area code prefix is completely legitimate, serving millions of residents and businesses. However, its association with affluent, trusted communities makes it a target for caller ID spoofing.
Common Scam Types to Watch For
Fake IRS calls claim the recipient owes back taxes — legitimate agencies never call this way. Tech support fraud involves callers impersonating Apple or Microsoft and requesting remote access. Prize scams request a fee to claim a supposed LA-based promotion.
How to Stay Protected
Never share personal information on an unsolicited call, and hang up if a caller demands gift cards or wire transfers. Choose a VoIP provider that supports STIR/SHAKEN to reduce spoofing.
The 310 Economy: Industries That Drive the Westside
Entertainment and Media
Sony Pictures Studios in Culver City is one of the most active production lots in the country, with Apple TV+, Amazon Studios, and HBO also expanding into the area.
Silicon Beach Technology
Silicon Beach spans Santa Monica, Venice, and Playa Vista, hosting Google, Snapchat, Hulu, and dozens of startups. The area generates commercial density that rivals traditional tech hubs.
Aerospace and Defense
El Segundo and Hawthorne form one of the country's most concentrated aerospace corridors. SpaceX and major defense contractors anchor a commercial space ecosystem across the South Bay.
Why a 310 Business Number Strengthens Your Market Position
A 310 area code number works in ways a national toll-free number cannot. Angelenos recognize 310 as a Westside and South Bay number — that recognition translates into higher answer rates before a word is spoken. A consistent 310 number in your Google Business Profile reinforces geographic relevance for LA-specific searches. You do not need a physical Westside office — virtual phone numbers route calls to any device, letting remote teams project a local presence instantly.
How to Get a Local 310 Business Number
1. Choose a VoIP or virtual number provider that maintains active 310 inventory — confirm live 310 stock before committing.
2. Browse and select your number. Most platforms let you filter by pattern or choose vanity options.
3. Configure call routing. Set up forwarding to mobile, IVR menus, or call queues through a browser dashboard.
4. Enable SMS for two-way text messaging alongside voice.
5. Port an existing number if needed. Local Number Portability rules let you transfer a 310 number to a new provider with no service gap.

What's Next for the 310 Region
Silicon Beach will keep growing. The tech ecosystem in Santa Monica, Venice, and Playa Vista continues to attract venture investment. The SoFi Stadium effect is still early — as Inglewood matures, its commercial ecosystem will expand. UCaaS adoption is accelerating, with entertainment companies replacing legacy PBX systems with cloud platforms. AI-enhanced call management — real-time sentiment analysis and intelligent routing — is now accessible to small and mid-sized businesses.
Conclusion
The 310 area code spans an extraordinary landscape — from aerospace corridors in El Segundo and Hawthorne to tech campuses in Silicon Beach, production lots in Culver City, and coastal estates in Malibu. For businesses, a 310 number signals local belonging, improves call answer rates, and supports local SEO. Paired with reliable VoIP technology, it becomes a competitive asset, not just a cosmetic choice.
