Introduction
The 424 area code is the overlay for the 310 — one of Los Angeles's most recognisable prefixes. Introduced on March 23, 2006 when 310 ran low on available numbers, 424 covers the same West Los Angeles and South Bay territory as 310 without any geographic difference.
The 424/310 zone encompasses some of California's most economically productive real estate: Beverly Hills, Santa Monica, Malibu, Culver City, El Segundo's aerospace corridor, and the South Bay beach cities. A 424 number instantly signals West LA to any caller — making it a high-value choice for businesses targeting this region.

History of the 424 Area Code
The 424 area code is the product of Los Angeles's extraordinary growth and the explosion of mobile phones in the 2000s.
- 1947: All of California assigned area code 213.
- 1951: 415 split for Northern California.
- 1984: 818 split from 213 for the San Fernando Valley.
- 1991: 310 split from 213 for West LA, the South Bay, and Long Beach.
- 1997: 562 split from 310 for Long Beach and southeast LA County.
- 2006 (March 23): 424 introduced as the first overlay for 310, after mobile phone and internet growth drove 310 to near-exhaustion.
- 2006–present: 424 and 310 co-exist as overlays across West LA and the South Bay.
The 424 overlay preserved the geographic identity of the 310 zone — the same affluent West LA and South Bay communities — while doubling the available number pool. Today, 424 and 310 are treated as fully equivalent by callers and carriers.

424 vs 310 — Which Should You Choose?
- 310 — the original 1991 code, slightly more prestigious for legacy business associations; harder to find in specific combinations
- 424 — equally valid West LA number since 2006; more available inventory; zero perception gap for most modern callers
- Both codes are fully equivalent in routing and functionality — choose based on number availability and personal preference
Scam Awareness: 424 Area Code Calls
Because 424 and 310 are associated with affluent West LA, scammers spoof these codes to appear as real estate agents, entertainment industry contacts, or financial advisors. Caller ID spoofing is cheap and requires no equipment. For more, see 424 area code.
- Never share financial or personal information with an unsolicited 424 caller
- Verify any 'investment opportunity' or 'industry contact' through official channels before responding
- Report suspicious 424/310 spoofed calls to the FCC at fcc.gov/consumers
- Enable carrier-level spam filtering — most US carriers provide free robocall blocking
Dialing a 424 Number from Abroad
West LA does business with the world — entertainment deals, aerospace suppliers, international investors — so 424 numbers receive calls from every continent. The dialing pattern is always the same: the caller's international exit code, the North American country code 1, then the full ten digits. From most of Europe that means 00 1 424 555 0123; mobile users everywhere can simply use the plus-sign format, +1 424-555-0123, which works on any modern network.
- Save contacts in full international format with the leading +1 so they dial correctly from any country.
- Remember Pacific Time — morning in Santa Monica is evening in Europe and the next morning in East Asia.
- Businesses expecting overseas callers should publish the +1 format on websites and email signatures to remove guesswork.
Porting an Existing Number Into or Out of the Overlay
US portability rules let a business keep its established West LA digits while changing carriers, moving from a landline to a cloud platform, or relocating within the region. The number itself is often the most valuable part of the phone setup — years of listings, referrals, and signage all point to it.
- 1Keep the existing service active until the port completes — canceling early can forfeit the number.
- 2Collect the account number, service address, and port-out PIN exactly as the current carrier has them on file.
- 3Submit the port order through the new provider and confirm the cutover date.
- 4Test inbound calls, voicemail, and caller ID after the switch, then close the old account.
Most local ports complete within a few business days, with no interruption callers would notice.
Setting Up Call Routing on a West LA Line
A local number earns its keep once intelligent routing sits behind it. Cloud platforms let a single line greet callers with an auto-attendant, offer menu options, and deliver each call to the right person — whether that person works from a Culver City studio, a Torrance office, or a home desk in another state entirely.
Useful patterns for businesses in this market include business-hours rules that send after-hours calls to transcribed voicemail, ring groups that ring an entire sales or booking team simultaneously, and failover paths that push calls to a mobile if the internet drops. A production company can route talent inquiries and vendor calls to different teams from one published number, and a South Bay contractor can escalate urgent jobs past the menu entirely. Everything is configured in a web dashboard and can be changed in minutes as the team grows.
Conclusion
The 424 area code covers the same West Los Angeles and South Bay geography as the iconic 310 — from Beverly Hills and Santa Monica to El Segundo's aerospace corridor, SpaceX in Hawthorne, and the stadium complex in Inglewood. Operating on Pacific Time, 424 is the accessible route to a credible West LA phone presence.
