818 Area Code: San Fernando Valley, Los Angeles — Cities, Overlay & Business Guide

The 818 area code is the telephone prefix of the San Fernando Valley — the broad, sun-baked basin on the northern side of Los Angeles that runs from Burbank and Glendale in the east to Calabasas and Hidden Hills in the west. It is the code of the studio lots, the soundstages, and the production offices that make Burbank one of the most concentrated media hubs on earth. An 818 number puts your business squarely inside that world.

This guide covers the full picture: which Valley cities and Los Angeles neighborhoods 818 serves, how it relates to its 747 overlay and to the neighboring 213, 323, and 310 codes, the code's history since 1984, and exactly how to activate an 818 virtual number for your business in minutes.

The 818 area code serves the San Fernando Valley region of Los Angeles County, plus a small slice of eastern Ventura County. It was created on January 7, 1984, when it was split from the original Los Angeles 213 area code to relieve number exhaustion across the rapidly growing metro.

Over the following decades the Valley's footprint was refined by two further splits — 626 for the San Gabriel Valley in 1997 and 661 for Santa Clarita and the Antelope Valley in 1999 — leaving 818 focused on the San Fernando Valley proper.

Dialing Format and Time Zone

• Dialing format: (818) 555-0142
• International: +1 818-555-0142
• Time zone: Pacific Time (PT) — UTC−8 Standard, UTC−7 Daylight Saving (March–November)
• 10-digit dialing required for all local calls due to the 747 overlay

The 818 area code maps almost exactly onto the San Fernando Valley. It stretches from the independent cities of Burbank and Glendale in the east to Calabasas, Hidden Hills, and Agoura Hills in the west, and it covers the entire northern arc of Los Angeles neighborhoods that ring the Valley floor. The city of San Fernando, an independent municipality entirely surrounded by Los Angeles, also sits inside 818.

• Burbank — independent city and the heart of the studio district; home to major film and television production
• Glendale — independent city on the Valley's eastern edge; a dense commercial and residential center
• Van Nuys — central Valley district and a major civic and government hub for the area
• North Hollywood — the NoHo Arts District, full of theaters, studios, and creative businesses
• Sherman Oaks — busy commercial corridor along Ventura Boulevard with a strong small-business base
• Encino — leafy residential community and professional-services pocket south of the Valley floor
• Northridge — home to California State University, Northridge and a large student and retail population
• Woodland Hills & Canoga Park — west Valley business districts including the Warner Center office cluster
• Reseda & Tarzana — established central and southwest Valley residential communities
• Chatsworth — northwest Valley district with light-industrial, logistics, and production-support businesses
• Calabasas, Hidden Hills & Agoura Hills — affluent west-end cities at the Valley's far edge

Together these communities form one of the most populous and recognizable suburban districts in the United States — a place the rest of the country simply calls the Valley.

The 818 area code observes Pacific Time (PT). That means UTC−8 during Pacific Standard Time in the winter months and UTC−7 during Pacific Daylight Time from mid-March through early November. The Valley keeps the same clock as the rest of Los Angeles, San Francisco, Seattle, and the entire West Coast.

For businesses, the practical implication is the three-hour gap with the East Coast. A 9 a.m. start in the Valley is already noon in New York, so teams selling into both coasts often front-load East Coast outreach in the morning and reserve the afternoon for local San Fernando Valley contacts. An 818 number on the line signals to those local contacts that you keep Valley hours.

On May 18, 2009, the 818 area code was overlaid with the new 747 area code. An overlay adds a second area code across the exact same geographic region rather than splitting it, so existing 818 customers kept their numbers while new lines could be assigned a 747 prefix. The trade-off is that 10-digit dialing became mandatory for every call in the area — you must dial the full area code even for a neighbor across the street.

• 747 — the direct overlay of 818, covering the identical San Fernando Valley footprint; newer numbers in the Valley often carry 747
• 661 — to the north, covering Santa Clarita and the Antelope Valley after the 1999 split from 818
• 626 — to the east, covering Pasadena and the San Gabriel Valley after the 1997 split from 818
• 213 and 323 — central and east Los Angeles, including Downtown and the original LA core
• 310 and 424 — the Westside, including Santa Monica, Beverly Hills, and the coastal communities

If you want recognition specifically in the San Fernando Valley, 818 is the prefix locals associate with home. For other parts of greater Los Angeles, see our guide to the 310 West LA area code and the 213 Los Angeles area code.

The 818 area code carries a business identity unlike almost any other code in the country, because the San Fernando Valley is where a huge share of the world's film and television content is physically made. Burbank in particular has earned the nickname the Media Capital of the World, and the surrounding Valley layers a deep, diversified local economy on top of that headline industry.

Entertainment and the Studios

Burbank is home to the Warner Bros. studio lot and the Walt Disney Studios, and it has hosted major NBC television operations for decades. Just over the hill in nearby Universal City sits Universal Studios. The result is a dense cluster of soundstages, post-production houses, talent agencies, and production-support firms across Burbank, Glendale, North Hollywood, and Studio City — much of it reachable on an 818 line.

Beyond the Backlots

The Valley is far more than film sets. Glendale anchors a major retail and corporate corridor, Warner Center in Woodland Hills is a substantial office and commercial cluster, and California State University, Northridge brings a large education and research presence. Healthcare, professional services, aerospace-adjacent manufacturing, and a deep bench of small and family-owned businesses round out the local economy.

Landmarks and Identity

From the NoHo Arts District to Ventura Boulevard, the Universal backlot to the Verdugo foothills, the 818 region has a strong sense of place. Decades of television and film have made the Valley and its area code a cultural shorthand, which is exactly why an 818 number reads as authentically local to anyone who knows Los Angeles.

You do not need an office in Burbank or a building on Ventura Boulevard to use an 818 number. Modern VoIP and cloud phone providers let you activate a San Fernando Valley 818 line in minutes, with no hardware and no long-term contract. Search the available 818 inventory, pick the combination you like, complete a short verification, and route the number to any device anywhere in the world.

An 818 number is a natural fit for production companies, post houses, talent and casting professionals, real estate agents, and any service business that wants to look established in the Valley. MeraTalk provides 818 virtual phone numbers as part of its cloud telephony platform — numbers activate in minutes and can be paired with call routing, voicemail, an auto-attendant, and CRM integration from a single dashboard.

Businesses that already hold an 818 number can keep it when switching providers thanks to local number portability. The prefix stays with the customer, not the carrier, so a production office moving from a legacy landline to a cloud platform carries its familiar digits along. The receiving provider handles the transfer once the account holder supplies a recent bill, the account number, and the porting PIN from the current carrier.

• Keep the old service active until the port completes — cancelling early can strand the number
• Confirm the billing name and address match the losing carrier's records exactly
• Ask the new provider for a temporary forwarding number so calls are never missed mid-transfer
• Port-out works the same way in reverse if a business later leaves the platform

Because 818 lines have often been in service for decades, porting is especially valuable here — a long-held Valley number carries recognition that a fresh line cannot replicate. For more, see 818 area code.

Caller ID spoofing lets fraudsters display an 818 prefix even when the call originates far outside California, and the Valley's mix of entertainment workers, students, and small businesses makes it a frequent target. Typical schemes include fake casting or talent-agency fees, utility disconnection threats demanding immediate payment, and bogus delivery notifications that harvest personal details.

• Legitimate studios, agencies, and government offices never demand gift cards or wire transfers by phone
• Let unknown local-looking calls go to voicemail — genuine callers leave a message
• Never share verification codes, banking details, or Social Security numbers with an inbound caller
• Report suspected fraud to the FTC and FCC so patterns can be traced

Businesses can protect their own reputation by using a provider that supports STIR/SHAKEN call authentication, which helps carriers flag spoofed traffic before it reaches customers.
