Introduction
Why does almost every major Hollywood production office, studio backlot, and talent agency dial the same three-digit phone code? The 818 area code is the answer — and its dial tone has powered American entertainment for over four decades.
Whether you're a producer setting up a new project office in Burbank, a digital marketing team chasing the Los Angeles market from out of state, or simply curious about that incoming 818 call, this guide answers every question about the 818 area code. We'll trace its geographic coverage, decode the 747 overlay that runs alongside it, recap its history, and show you exactly how to get an 818 number for business or production use.

The 818 Area Code and the San Fernando Valley
The 818 area code covers the San Fernando Valley region of Los Angeles County, California, plus a handful of surrounding communities. The Valley itself is a sprawling sub-region of LA stretching from the Hollywood Hills in the south to the Santa Susana Mountains in the north.
The 818 area code does NOT cover central Los Angeles, Pasadena, or Santa Clarita. It is the dedicated dial tone of the Valley.
- Communities served: Burbank, Glendale, North Hollywood, Sherman Oaks, Encino, Van Nuys, Studio City, Universal City, Woodland Hills, Calabasas, San Fernando
- State: California (CA) · County: Los Angeles County
- Neighboring codes: 626 (Pasadena), 661 (Santa Clarita), 310/424 (West LA), 213/323 (Central LA)
- Combined population with 747 overlay: approximately 1.7 million
- Approximate footprint: 260 square miles
Hollywood North: Entertainment Industry's Phone Code
Although Hollywood as a neighborhood technically sits in the 323 area code, the actual production infrastructure that builds Hollywood content lives almost entirely inside the 818 area code. The Valley earned the nickname Hollywood North for hosting an unmatched concentration of studio campuses, post-production houses, talent agencies, and production services.
That density is why an 818 phone number carries serious cachet inside the entertainment business. For out-of-state production companies, getting an 818 local phone number signals direct phone-line proximity to the people who green-light projects, sign contracts, and write checks.
- Warner Bros. Studios (Burbank) — film, TV, animation
- The Walt Disney Studios (Burbank) — film, animation, corporate HQ
- Universal Studios Hollywood (Universal City) — theme park, NBCUniversal HQ
- DreamWorks Animation (Glendale) and Disney Animation Studios (Burbank)
- CBS Studio Center (Studio City), Cartoon Network Studios and Nickelodeon Animation Studio (Burbank)
From 213 to 818: A History of California's Splits
The 818 area code was created in 1984, when AT&T split the original Los Angeles area code (213) to ease number exhaustion. Until then, 213 had served all of LA County since 1947.
The 1984 split moved most of the San Fernando Valley, Pasadena, Glendale, and surrounding communities into the new 818 area code.
In 1997, growing demand forced another split: Pasadena and the San Gabriel Valley moved into the new 626 area code, leaving 818 to serve just the San Fernando Valley. All US area code assignments and split decisions are coordinated by the North American Numbering Plan Administrator, which tracks inventory and approves overlays.
The 818 + 747 Overlay and Today's Coverage Map
By the mid-2000s, mobile-phone proliferation pushed 818 toward exhaustion. Rather than splitting the Valley — which would have forced thousands of studios and production offices to reprint business cards and update credit references — the California Public Utilities Commission opted for an overlay.
The 747 overlay went live in May 2009, sharing the exact same geographic footprint as 818.
Businesses that provision Valley numbers through wholesale VoIP origination can request either 818 or 747 inventory depending on availability. Vanity-grade 818 numbers carry a premium because demand outstrips supply, and established 818 numbers are treated as more prestigious by Hollywood insiders simply because the code is older.
- All calls within the 818/747 region must use 10-digit dialing
- New customers may receive either an 818 or 747 number depending on inventory
- Vanity-grade 818 numbers carry a premium because demand outstrips supply
- Existing 818 numbers retained their digits with zero renumbering
Time Zone, Studio Hours, and Bicoastal Business
The 818 area code operates in the Pacific Time Zone (PT) — Pacific Standard Time (UTC-8) in winter and Pacific Daylight Time (UTC-7) from March through November.
Production schedules in the Valley are notoriously early. Major studios start workdays at 6–7 a.m.
PT for crews on set, and production office phones often run until 10 p.m. PT during active production.
An 818 virtual number routed through SIP trunking to a globally distributed contact center keeps Hollywood-aligned operating hours regardless of where calls are physically answered.
- East Coast / Pacific overlap: 9 a.m.–noon PT equals 12–3 p.m. ET — the daily studio-to-network window
- London coordination: 7 a.m. PT equals 3 p.m. GMT
- Asia-Pacific aligns with Pacific evenings: 6 p.m. PT equals 11 a.m. Tokyo next-day
“The 818 area code is more than a phone prefix — it is the dial tone of the American entertainment industry, anchoring the studios, talent agencies, and production houses that build Hollywood content.”
How to Get an 818 Area Code Number for Your Business
Getting an 818 area code phone number is straightforward whether you're based in the Valley or expanding into LA from elsewhere.
For Valley and LA-based businesses: Local landline providers (Spectrum, AT&T, Lumen) offer 818 business lines. Mobile carriers assign 818 numbers locally, though many new mobile assignments now default to 747 due to inventory pressure.
For out-of-state businesses wanting an 818 virtual presence: Wholesale VoIP providers issue 818 DIDs nationally and globally. Numbers route to any SIP endpoint, cloud PBX, mobile phone, or contact center platform.
Calls present a Valley local presence even when answered from another time zone. E911 must be registered to a real responder-reachable address.
Teloz wholesale origination delivers 818 area code DIDs within minutes through our portal or API. Whether you need a single number for a Hollywood-bound sales line, a 50-number block for a production accounting office, or a fully integrated cloud PBX for a talent agency expansion, the same self-serve provisioning applies.
Conclusion
The 818 area code has remained the trusted phone identity of the San Fernando Valley and the studios, talent agencies, and production houses that build Hollywood content — from its 1984 split off of 213 to today's overlay with 747. Whether you're claiming local roots, expanding into the LA entertainment market, or simply curious about that incoming Valley call, the right 818 phone number is a meaningful brand signal in one of America's most influential business regions.
