Area Code Overlay Approved for 818 Area Code
To ensure a continuing supply of telephone numbers, the 747 area code will be added to the area served by 818. Get ready to change the way you dial your calls!
Who Will be Affected?
All customers with an 818 number will have to change the way they dial.
The new 747 area code will serve customers in the same geographic region
as the current 818 area code, which includes the communities in the San
Fernando Valley, as shown on the map, and small parts of Pasadena and
Thousand Oaks. This is known as an area code overlay.
What is an Area Code Overlay?
An overlay is the addition of another area code (747) to the same
geographic region as an existing area code (818). overlay does
not require customers to change their existing area code.
What Will be the New Dialing Procedure?
To complete calls from a landline phone, the new dialing procedure
requires callers to dial 1 + area code + telephone number. This means
that all calls in the 818 area code that are currently dialed with seven
digits will need to be dialed using 1+ area code + telephone number.
To complete calls from a cellular or mobile phone, callers may dial the
area code + telephone number or 1 + area code and telephone number
whenever placing a call from a phone number with the 818 or 747 area code.
When Will the Change Begin?
Effective October 11, 2008, you should begin using the new dialing procedure whenever
you place a call from the 818 area code. If you forget and use the old dialing procedure
of dialing just seven digits, your call will still be completed.
Beginning April 18, 2009, you must use the new dialing procedure for all calls.
After this date, if you do not use the new dialing procedure, your call will not
be completed, and a recording will instruct you to hang up and dial again.
Beginning May 18, 2009, new telephone lines or services may be assigned numbers with the 747 area code.
What Will You Need to Do?
In addition to changing your dialing procedure, all services, automatic dialing equipment,
or other types of equipment that are programmed with a 7-digit telephone number will need
to be reprogrammed to use the new dialing procedure. Some examples are life safety systems,
fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, mobile
phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to
check your business stationery, advertising materials, personal checks, and your pet’s ID tags to
ensure the area code is included.
What Will Remain the Same?
- Your telephone number, including current area code, will not change.
- The price of a call, coverage area, or other rates and services will not change due to the overlay.
- What is a local call now will remain a local call regardless of the number of digits dialed.
- You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811.
