What Is the 747 Area Code?

The 747 area code is a telephone overlay prefix assigned to the San Fernando Valley in Los Angeles, California. It covers the same geographic territory as the existing 818 area code, which has served the Valley since 1984. Both codes are active today, and callers receive one or the other based on number availability when new lines are issued.

Area Code 747 was introduced on January 3, 2009, to address the growing demand for new phone numbers in one of Los Angeles' most populated regions. As smartphones multiplied and businesses expanded, the supply of available 818 numbers began to run short — prompting regulators to add 747 as an overlay rather than splitting the Valley into separate geographic zones.

Overlay Code: Why 747 and 818 Coexist

An overlay adds a new area code to an existing territory without dividing it between two separate populations. The 747 overlay shares the entire 818 footprint, which means a call between a 747 number and an 818 number within the Valley is treated as a local call — no long-distance charges apply. This approach preserves existing numbers and avoids forcing millions of residents and businesses to update their contact information.

Ten-Digit Dialing in the 747 Zone

Because two area codes share the same space, ten-digit dialing is mandatory for every call placed within the 747 and 818 zone. You must dial the complete area code plus the seven-digit local number — even when calling a neighbor across the street. Businesses running VoIP systems, auto-dialers, or multi-line phone setups in the Valley must configure all platforms for full ten-digit dialing from day one.

Where Is the 747 Area Code Located?

The 747 area code is located in the San Fernando Valley, a broad basin in the northern portion of Los Angeles County. The Valley is bordered by the Santa Monica Mountains to the south, the Santa Susana Mountains to the west, and the San Gabriel Mountains to the north and east.

The San Fernando Valley covers approximately 260 square miles and is home to more than 1.8 million residents — making it one of the most populous sub-regions in California. It blends residential neighborhoods, major corporate campuses, world-famous entertainment studios, and thriving retail corridors across dozens of distinct communities.

Neighboring Area Codes at a Glance

The 747 zone borders several surrounding Los Angeles area codes. Knowing these helps you identify calls from adjacent communities across the greater LA region.

747 Area Code Time Zone

The 747 area code operates on Pacific Time (PT). During winter, the San Fernando Valley observes Pacific Standard Time (PST, UTC-8). From the second Sunday of March through the first Sunday of November, the zone shifts to Pacific Daylight Time (PDT, UTC-7).

For callers on the East Coast, this prefix runs three hours behind Eastern Time. A business call at 3:00 PM EST reaches a Valley contact at noon Pacific — plan outreach for mid-morning Pacific hours to connect during their prime work window.

The 747 area code shares its Pacific Time schedule with other Southern California codes, including the 714 area code in nearby Orange County — making cross-region scheduling across the greater LA area simple and consistent.

History of the 747 Area Code

The 818 Foundation

The story of the 747 area code begins in 1984, when the 818 area code was split from the original 213 Los Angeles prefix. At that time, 213 served all of Los Angeles County — but rapid population growth forced regulators to carve out a separate code for the San Fernando Valley and surrounding communities. The 818 code served the Valley for more than two decades without interruption.

Growing Demand Brings 747 to Life

By the mid-2000s, the explosive growth of mobile phones, fax machines, internet dial-up connections, and business lines had consumed much of the available 818 number supply. Regulators faced a choice: split the Valley into two separate zones — forcing millions of people to change their numbers — or add an overlay. They chose the overlay, and the 747 area code became active on January 3, 2009. This approach mirrors the overlay strategy used across high-growth markets, similar to what the 619 area code region experienced with its own California number pressures. Overlays remain the preferred solution when geographic splits would force mass number changes across millions of active subscribers.

A recognizable local prefix signals that you are part of the community — and that matters in a market built on personal relationships.

Burbank alone hosts Warner Bros. Studios, The Walt Disney Company headquarters, and NBC Universal — making the 747 zone one of the most entertainment-dense telephone prefixes in the world. Production companies, talent agencies, post-production houses, and creative freelancers all benefit from a local Valley number that keeps their outreach in the trusted local tier for every industry contact they reach.

Beyond entertainment, the Valley is a hub for healthcare, finance, aerospace (Northridge has aerospace manufacturing roots), real estate, and retail.

According to the NANPA database, overlays like 747 are assigned specifically to preserve existing numbers while adding fresh capacity to high-growth regions.

Is a 747 Area Code Call a Scam?

The 747 area code is a legitimate Los Angeles telephone prefix and carries no inherent connection to fraud. As a recognized San Fernando Valley code, 747 is occasionally spoofed by scammers who use local number recognition to increase pickup rates — a tactic that targets nearly every major metro area code in the country.

Common patterns include fake utility notices, IRS and Social Security impersonation, entertainment industry casting scams, and local business fraud. If an unsolicited caller creates urgency and requests payment or personal information, end the call immediately and contact the organization through its official published channel.

How to Stay Safe

Let unknown calls go to voicemail first. Search any unfamiliar 747 phone number online before returning the call to check for reported scam activity. No legitimate Los Angeles agency, utility company, studio, or financial institution will ever demand your personal information or payment through an unsolicited phone call.
