818 Area Code: San Fernando Valley, California Location and Time Zone

Introduction

The 818 area code is the San Fernando Valley's number, reaching places such as Burbank, Van Nuys, Northridge and San Fernando across the greater Valley in Los Angeles County. It began in 1984 as a split from 213, and in 2009 the overlay code 747 was layered onto the same territory, which is why every call there is dialed with a 1 and ten digits. The whole area keeps Pacific Time.

Picture a missed call from (818) 555-0163. Is it a shop in Burbank, a dentist in Northridge or a spoofed robocall? The sections below cover the code's territory and history, the 747 overlay, dialing rules and some practical checks before you call back.

Where Is the 818 Area Code?

Ask "area code 818 is where?" and the short answer is the Valley. The California Public Utilities Commission (CPUC) describes 818 as serving the greater San Fernando Valley area of Los Angeles County in Southern California.

The territory used to be part of 213, one of California's three original area codes from 1947. In 1984 the Valley was split off as 818, and in June 1997 the code itself was split, with part of its area moving to the new 626.

When the CPUC weighed adding a second code in 2008, it held public meetings in Burbank, Calabasas, San Fernando and Van Nuys. Those four towns give a rough sense of how far the 818 map stretches from one side of the Valley to the other.

Cities and Communities in the 818 Area Code

All of 818 lies in Los Angeles County. Phone numbers are tied to rate centers, the local serving areas that prefixes are assigned to, and the CPUC's 2000 report on the code listed these rate centers inside 818:

• Burbank and Burbank Sun Valley
• Glendale and La Crescenta
• North Hollywood and Van Nuys
• Northridge, Reseda and Canoga Park
• San Fernando, plus San Fernando Granada Hills, San Fernando Pacoima and San Fernando Sepulveda
• Sunland Tujunga
• Pasadena and Pasadena La Canada
• Agoura

These are phone-network labels, not city limits. Some names also show up in neighboring codes: Glendale and Pasadena appear in the CPUC's city list for the 213/323 region too, so a phone line in those cities may carry 818 or 213/323 depending on its rate center. The 747 overlay uses exactly the same map as 818.

818 Area Code Time Zone (Pacific Time)

The San Fernando Valley runs on Pacific Time like the rest of California. The legal definition is geographic: 49 CFR 71.10 places the continental US west of the Mountain-Pacific boundary line in the Pacific zone, and 15 U.S.C. 261 puts its standard time at UTC minus eight hours.

Clocks spring forward to Pacific Daylight Time (UTC-7) on the second Sunday of March and fall back to Pacific Standard Time (UTC-8) on the first Sunday of November, both at 2 a.m. For a caller in Chicago, a 9 a.m. appointment in Van Nuys is 11 a.m. Central; from New York it's noon.

818 and 747: One Area, Two Area Codes

NANPA, the national numbering administrator, found that 818 was running out of whole prefixes and applied on behalf of the phone industry for an all-services overlay. The CPUC granted it in Decision 08-04-059 on April 24, 2008. Nobody had to give up an 818 number; the new 747 code would simply be added over the same territory.

The decision set a 13-month rollout. Callers could try the new dialing pattern about six months in, it became mandatory on April 18, 2009, and from May 18, 2009, new lines or services could be assigned 747 numbers. The CPUC's reminder that spring stressed that existing numbers, call prices and calling areas would stay the same.

Because 747 was layered on top of 818 rather than carved out of it, a 747 number is exactly as local to Van Nuys or Burbank as an 818 number. The 747 area code guide covers that code on its own; for most purposes, treat the two as interchangeable labels for the Valley.

Is 818 a Country Code? What That Search Really Means

No. 818 is an area code inside the North American Numbering Plan, in which the United States uses country code 1. Written for an international caller, a Valley number looks like +1 818 555 0163, and the leading 1 is the country code.

The mix-up tends to happen with numbers saved without spaces, where a string starting 1818 reads like one long foreign prefix. Split it as 1, 818 and seven digits and the meaning is clear. When someone abroad needs to reach you, give them the full +1 818 form so they don't have to guess.

818 Area Code vs ZIP Codes

There's no single "818 area code ZIP code," even though that's one of the more common searches about this number. Telephone area codes and USPS ZIP codes were drawn for different networks, so the 818 region contains many ZIP codes, and ZIP boundaries don't stop at the edge of a rate center.

For mail, look up the ZIP code by street address or by city on usps.com. For a phone number, the code only says the line was assigned somewhere in the 818/747 region; it can't point to a street or a neighborhood.

How to Tell If a Call From 818 Is Legitimate

An 818 number on your screen means the line was issued in the Valley. It doesn't prove who's on the other end, because caller ID can be faked, and the FTC specifically warns about calls rigged to display your own area code so they seem local.

Signs the Call Isn't What It Claims

Be suspicious when the caller insists you act immediately, says you owe money to a government agency or utility, asks for a card number or bank login, or wants you to read back a verification code that was just texted to you. A recorded voice telling you to press 1 belongs in the same pile.

What to Do Instead

1. 1End the call and look up the organization's official number yourself before calling back.
2. 2Skip the keypad during robocalls; the FTC says pressing a number can lead to more robocalls.
3. 3Block the number with your phone's built-in feature, a call-blocking app or your carrier's service.
4. 4Report scams at ReportFraud.ftc.gov and unwanted sales calls at DoNotCall.gov.

How to Dial an 818 Phone Number

Since April 18, 2009, the CPUC has required callers in the 818 area to dial 1 + area code + telephone number, including for a call across the street. Here is how that plays out:

• From an 818 or 747 phone: 1 + 818 + the seven-digit number (or 1 + 747 for a 747 line).
• From elsewhere in the country: the same 1 + 818 pattern, followed by the local seven digits.
• From outside the US: your country's exit code, then 1, 818 and the number.

Anyone programming equipment that dials by itself, such as an alarm panel, a door entry system or a call forwarding rule, should store the full 11 digits, 1 plus ten, rather than a short local form.

How to Get an 818 Phone Number for Your Business

An 818 number reads as local to customers in Burbank, Van Nuys or Northridge, and you don't need a Valley office to use one: a cloud phone number rings wherever your team works. New lines in the region can be assigned 818 or 747, which are equally local, so decide whether the specific digits matter to you before you start.

With Ringflow, setup follows four steps:

• Search the US area codes list and check availability for 818, or for 747 if you're flexible.
• Send calls to Ringflow's mobile and desktop apps, or put an auto attendant in front of the line.
• Turn on business texting for customers who would rather message.
• Keep a number you already use by porting it instead of starting over.

A free trial lets you test the call routing before the number goes on your website or van.

Conclusion

The 818 area code covers the greater San Fernando Valley in Los Angeles County. It split from 213 in 1984, lost part of its area when 626 arrived in 1997, and has had 747 layered over it since 2009, so either code signals a Valley line and both need 1 plus ten digits on every call.

An unfamiliar 818 caller is usually just a Valley number, but spoofing is easy, so verify any request for money or codes before acting. For a Valley presence of your own, check 818 availability and try Ringflow free.
