424 Area Code: West Los Angeles & South Bay — Complete Guide

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.

The 424 area code covers western and southern Los Angeles County — the same footprint as 310. It does not cover downtown LA (213/323), the San Fernando Valley (818/747), or the San Gabriel Valley (626/323).

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

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.

• 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
