The 747 area code serves the San Fernando Valley in Los Angeles County, California. It's an overlay of the original 818 area code, which has served the region since 1984. 747 launched on May 18, 2009, after the 818 pool of numbers ran low, driven by a dense population, mobile phones, and more business lines. The overlay brought fresh numbers to a community of over 1.8 million residents. The San Fernando Valley — 'The Valley' to Southern Californians — is home to the world's most famous entertainment studios and a long aerospace history. It's also one of the most diverse urban communities in the country.

This guide is for anyone who got a call from an unfamiliar 747 number, or a Valley business owner comparing phone options. It's also for a business building a local Los Angeles presence from outside Southern California. It covers what you need to know: the area code's history, its geographic reach, and mandatory 10-digit dialing. It also covers the entertainment economy, scam protection, and how to get a 747 number from anywhere.

What the 747 Area Code Covers

Area code 747 covers the entire San Fernando Valley, a large flat basin in northwestern Los Angeles County. The Santa Monica Mountains separate it from the LA Basin. The 747/818 area includes Burbank and Glendale in the east, and Van Nuys and North Hollywood in the center. To the west sit Encino, Tarzana, Woodland Hills, and Calabasas. The city of San Fernando, at the northern tip, along with Chatsworth and Northridge near the Simi Valley border, round out the map.

Burbank is the entertainment capital of the 747/818 region. It's home to the headquarters and studio lots of Walt Disney Studios, Warner Bros. Entertainment, and NBCUniversal — one of the biggest clusters of film and TV production in the world. Glendale has grown into a major Armenian-American cultural and business hub. The whole region runs on Pacific Time (PST/PDT), the same clock as Silicon Valley and the wider California tech and entertainment world. The 818 guide covers the neighboring ground.

History of the 747 Area Code

The San Fernando Valley was part of the 213 area code until 1984. That year, 818 split off to serve the Valley and the eastern LA suburbs. Through the 2000s, mobile phones, internet lines, and VoIP services used up 818 numbers faster than regulators expected. By the mid-2000s, 818 was running out. California regulators had two choices: a geographic split, which forces millions of people to change their numbers, or an overlay, which doesn't.

They chose the overlay, and area code 747 formally launched on May 18, 2009. New numbers in the Valley started getting 747 prefixes, while every existing 818 number stayed the same. The launch also made 10-digit dialing mandatory for every call in the 747/818 region, even calls between two neighbors who both have 818 numbers. That rule still stands today. It's the one practical change anyone in the Valley actually notices from the 747 overlay. More detail sits on our letsdial page.

Phone Number Format and Dialing Guide

All 747 numbers follow the standard 10-digit format: 747-XXX-XXXX. Because 747 overlays 818, 10-digit dialing is required for every call in the San Fernando Valley — even a call from one 818 number to another in the same neighborhood. There's no 7-digit local dialing anywhere in the 747/818 area, and that's been true since 2009. Several other LA-area overlays work the same way, so this is standard practice across Southern California.

International callers should dial +1 747 XXX XXXX. US callers from outside California dial 1-747-XXX-XXXX. The 747/818 region runs on Pacific Standard Time (UTC-8) in winter and Pacific Daylight Time (UTC-7) in summer. East Coast partners scheduling calls with Valley entertainment or aerospace contacts should aim for mid-morning to mid-afternoon Eastern time.

Industries and Economy in the 747 Region

Entertainment and media define the 747/818 area code. Walt Disney Studios, Warner Bros. Entertainment, and NBCUniversal all keep their main studio lots and headquarters in Burbank, within a few miles of each other. That closeness creates a remarkable cluster of film production, post-production, talent agencies, and specialized vendors. The entertainment economy brings in tens of billions of dollars a year and supports tens of thousands of jobs across the region.

Aerospace and technology form the second pillar of the local economy. Lockheed Martin's Skunk Works division in Burbank designed the U-2 spy plane, the SR-71 Blackbird, and the F-117 stealth fighter. The Valley's aerospace history has grown into defense electronics, aerospace parts, and tech companies. Many are drawn here by Hollywood's need for production technology and the wider LA startup scene. Healthcare, retail, and professional services for 1.8 million residents round out the local economy.

Spam, Robocalls, and How to Stay Safe

Like every US area code, scammers use 747 numbers to spoof caller ID. They pick local-looking Valley numbers because residents are more likely to answer a call from their own area. The entertainment industry brings its own scams here. Fake casting-agency calls, bogus talent-scout calls, and 'screen actors' scams targeting working actors are some of the most common tricks in the region. People also report a lot of fake Southern California Edison and IRS calls.

Register your number at donotcall.gov, report suspicious calls to the FTC at reportfraud.ftc.gov, and use call-blocking apps like Nomorobo or Hiya. Entertainment workers should be extra careful — real casting directors don't cold-call actors from unknown numbers asking for personal information or upfront fees. Apply STIR/SHAKEN A-level attestation through your carrier so every outbound 747 call arrives verified, and register text campaigns for 10DLC compliance.
