The 310 area code covers West Los Angeles — Beverly Hills, Santa Monica, Malibu, Long Beach, and the South Bay. This guide covers its history, the cities it serves, business benefits, dialing format, and how to get a 310 virtual number.
Few area codes in the United States carry as much cultural weight as 310. It is the number of Beverly Hills mansions, Santa Monica startups, Malibu beachfront homes, and some of the most recognizable business addresses on the planet. In Los Angeles, your area code says something about where you operate — and 310 says West LA.
The 310 area code covers the western and southern portions of Los Angeles County, including Beverly Hills, Santa Monica, Culver City, El Segundo, Torrance, Long Beach, and the entire South Bay coastline. It was carved out of the original 213 area code in 1991 as LA's explosive growth made it impossible to serve the entire county with a single prefix.
Whether you are a West LA business building local credibility or a company anywhere in the world looking to establish a premium Los Angeles identity, a 310 virtual number gives you instant presence in one of the most sought-after markets in the United States.
The 310 area code is a North American Numbering Plan (NANP) area code assigned to the western and southern portions of Los Angeles County, California. It covers coastal and inland communities stretching from Malibu in the north to Long Beach in the south, and inland through Beverly Hills, Culver City, and the South Bay cities.
The 310 area code operates in the Pacific Time Zone (PT) — PST (UTC−8) in winter and PDT (UTC−7) in summer.
The 310 service area spans a large portion of western Los Angeles County, covering a population of more than 4 million residents across coastal cities, the South Bay, and portions of the LA Basin.
When the North American Numbering Plan launched in 1947, the entire Los Angeles region was assigned the single area code 213. For over four decades, 213 served everything from Downtown LA to Malibu, Beverly Hills to Long Beach.
By the late 1980s, LA's booming population and the explosion of fax machines, pagers, and second phone lines exhausted the 213 number pool. On November 2, 1991, the 310 area code was split from 213, taking over the western and southern portions of LA County — Beverly Hills, Santa Monica, the South Bay, and Long Beach.
As demand continued to grow, the Long Beach and southeast LA communities were split off from 310 in 1997 into the new 562 area code — though much of Long Beach still carries 310 numbers from before the split.
By the mid-2000s, 310 numbers were running low again. On June 10, 2006, the 424 area code was introduced as an overlay for the entire 310 territory. New phone numbers in West LA began receiving 424 codes, while all existing 310 numbers remained intact. Today both 310 and 424 serve the same West LA geography — 310 numbers carry significantly more prestige.
The 310 area code covers a wide range of cities and communities across western and southern Los Angeles County:
A 310 number is one of the most recognizable and prestigious area codes in the country. Through a cloud UCaaS phone system, you can get a 310 area code number and route calls to any device, anywhere — no West LA office required.
Santa Monica and Culver City form the heart of Silicon Beach — LA's answer to Silicon Valley. Amazon, Apple, Google, Snap, and hundreds of startups operate here. A 310 number signals that you are part of this ecosystem. Combined with Beverly Hills' entertainment industry concentration, 310 is the area code of choice for agencies, studios, talent managers, and tech companies targeting the LA premium market.
In business, perception matters. A 310 number carries the brand equity of Beverly Hills and West LA — instantly communicating premium positioning to clients, partners, and investors. Inbound calls from a 310 number see significantly higher answer rates than unknown out-of-state codes.
A modern UCaaS platform turns your 310 number into a complete communication hub — voice, SMS, video meetings, and team messaging all on one platform, built for distributed teams operating across time zones.

Since the 424 overlay was introduced in 2006, 10-digit dialing is mandatory for all calls in the 310 area — even local calls between two 310 numbers in the same neighborhood.
Format: 310-XXX-XXXX
When calling a 310 number from another country, use your country's international exit code, followed by the US country code +1, then the full 10-digit number.
Format: [Exit Code] + 1 + 310 + 7-digit number
Example from UK: 00 1 310 555 0100
Format: 011 + [country code] + [local number]
Example to UK: 011 44 20 XXXX XXXX
The 310 area code is used across the unique mix of industries that define the West LA economy:
Los Angeles is served by multiple area codes, each associated with a distinct part of the city. If you have read our 213 area code guide, here is how 310 fits into the broader LA picture:
| Area Code | Area Covered | Known For | Best For |
|---|---|---|---|
| 310 | West LA, South Bay | Beverly Hills, Santa Monica, Silicon Beach | Premium brands, entertainment, tech |
| 424 | West LA (overlay) | Modern West LA numbers | New lines in the same 310 territory |
| 213 | Downtown LA (original) | Historic prestige, financial district | Finance, law, corporate |
| 323 | Central/East LA, Hollywood | Hollywood, creative industries | Media, arts, music |
| 818 | San Fernando Valley | Entertainment studios, aerospace | Valley-based businesses |
Bottom line: Choose 310 for authentic West LA identity and premium market positioning. If you specifically need a Downtown LA or Hollywood association, 213 or 323 may serve better. The 424 overlay covers the same geography as 310 but lacks the brand recognition.
The prestige and recognition of the 310 area code across LA and nationally makes it a frequent target for caller ID spoofing — where scammers display a fake 310 number to increase answer rates.
If your own 310 number is being spoofed, contact your VoIP provider immediately and file reports with both the FTC and the FCC.
