About 424 Area Code
Area code 424 serves West Los Angeles and the South Bay region of California. Introduced on July 26, 2006 as an overlay to the existing 310 area code, 424 covers prestigious communities including Santa Monica, Beverly Hills, Malibu, Culver City, Torrance and Redondo Beach across Los Angeles County. The code extends to Santa Catalina Island, 26 miles offshore. Both 424 and 310 share the same geographic footprint, providing local voice and SMS-capable numbers for businesses targeting this affluent and culturally significant market.
The 424 region hosts entertainment studios, tech startups, aerospace firms, and luxury retail. Companies in Santa Monica and Culver City use 424 numbers for customer support, appointment scheduling, delivery coordination and outbound sales.

Industries ranging from hospitality and tourism to film production and professional services rely on recognizable West LA numbers to build customer trust and drive conversions.
FoneSwift displays live 424 inventory with full Voice, SMS and MMS capabilities. Availability fluctuates as demand for West LA numbers remains strong.

Many West LA businesses maintain consistent numbers to preserve brand recognition and customer familiarity across campaigns.

How Does Local 424 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 424 number in Santa Monica and California, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (424): directs the call to the Santa Monica / California region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 424 555 1234 |
| Local Format (National) | (424) 555-1234 |
