Area Code Splits & Overlays

What is an area code split?
The exhausting area code is split into two or three geographic areas, leaving the existing area code to serve on side of the geographic area and assigning one or two new area codes to the other segment(s).

What is an area code overlay?
An area code overlay occurs when more than one area code serves the same geographic area. In an area code overlay, relief is provided by opening up a new area code within the same geographic area as the area code requiring relief. With an overlay, all current customers keep their area code and telephone number. Numbers from this new area code may be assigned to new telephone customers or those adding additional lines. Because two area codes reside in the same geography, all calls must be dialed using the area code + the seven-digit telephone number (10 digits). (Some states require 1+10-digit dialing)

What is 10-digit dialing?
10-digit dialing is a term used to refer to the practice of including the area code of a phone number when making local calls. It is the required dialing pattern in locations throughout the country that have undergone an area code Overlay. For example, if area code (123) is overlaid with area code (456), then callers within the area served by 123/456 must dial 10-digits in order to place a local call even if the call is from a (123) number to another (123) number. Pre-subscribed long distance calls still require 1+10-digit dialing. Consumers in areas subject to an Overlay should replace all 7-digit telephone numbers programmed into their wireless phones and other devices with 10-digit telephone numbers.

What is Permissive Dialing?
The permissive dialing* period begins with the introduction of the new area code and generally lasts approximately six months. It provides a 'get acquainted' transition period for the new area code. Permissive dialing allows the old and new area code customers to call between the two area codes using seven-digit dialing. During this period, customers should begin to use the area code + the telephone number although calls will still complete if only the seven-digit telephone number is dialed. Customers, from outside the area, can call the new area code by dialing either the old or the new area code + the telephone number; the call will complete during the permissive period.
(* The permissive dialing period varies in length per commission decision)

What is Mandatory Dialing?
Approximately six months after the introduction of the new area code, an intercept recording* period will begin. At this time, callers must use the appropriate area code plus the telephone number. Calls incorrectly dialed will be referred to a recording throughout the recording period. It will inform the calling party that the new area code must be used to complete the call.

If you have family or friends deployed in the military outside of the United States, make sure they know and use your new area codes.

Boundary Elimination Area Code Overlay Approved for the 323 Area Code

To ensure a continuing supply of telephone numbers, the boundary between the current geographic region served by the 323 and 213 area codes will be eliminated so that both area codes will serve the same geographic region. This is known as a boundary elimination area code overlay. Get ready to change the way you dial your calls!
 
What is a boundary elimination area code overlay?
In this case, the boundary line between the 323 and 213 area codes is being eliminated so that the existing 213 area code will serve the same geographic region as the existing 323 area code, and conversely, the existing 323 area code will serve the same geographic region as the existing 213 area code. In other words, the two areas served by the 213 and 323 area codes are being combined and telephone numbers for either area code will be assigned in the new combined area. A boundary elimination area code overlay does not require customers to change their existing area code but does require customers to dial at minimum the area code + telephone number on every call, including calls within the same area code.
 
Who will be affected?
The 323 area code, in addition to serving a large portion of the City of Los Angeles, currently serves the cities of Alhambra, Bell, Bell Gardens, Beverly Hills, Commerce, Cudahy, Glendale, Hawthorne, Huntington Park, Inglewood, Lynwood, Maywood, Montebello, Monterey Park, Pasadena, Rosemead, South Gate, South Pasadena, Vernon and West Hollywood. The 213 area code currently serves the downtown portion of the City of Los Angeles and is surrounded by the 323 area code. Once the boundary elimination area code overlay is implemented, both area codes will serve the combined region.
 
What will be the new dialing procedure

To complete calls from a landline phone, the new dialing procedure requires anyone with a 323 or 213 area code to dial 1 + area code + telephone number. This means that all calls in the 323 and 213 area codes 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 + telephone number whenever placing a call from a phone number with the 323 or 213 area code.
 
When will the change begin?
Effective January 14, 2017, you should begin using the new dialing procedures whenever you place a call from the 323 or 213 area codes. If you forget and dial just seven digits, your call will still be completed.
 
Beginning July 8, 2017, you must use the new dialing procedures, as described above for all calls. After this date, if you do not use the new dialing procedures, your calls will not be completed and a recording will instruct you to hang up and dial again.
 
Beginning August 1, 2017, new telephone lines or services in the former 323 area may be assigned numbers using the 213 area code, and conversely, new telephone lines or services in the former 213 area may be assigned numbers using the 323 area code.
 
What will you need to do?
In addition to changing your dialing procedures, all services, automatic dialing equipment, or other types of equipment that are programmed with a 7-digit number will need to be reprogrammed to use the new dialing procedures. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, alarm and security systems and gates, speed dialers, call forwarding settings, voicemail services, etc. You may also want to check your personal and business stationery and checks, advertising materials, websites, contact information, and personal or pet 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.

Schedule and Locations of Local Jurisdiction and Public Meetings

LOCAL JURISDICTION AND PUBLIC MEETINGS REGARDING ADDING NEW AREA CODE TO THE 510 AREA CODE

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 510 area code, as the 510 is expected to use up its available prefixes by June 2019. The telecommunications service providers have proposed to introduce the new area code through the overlay method. Adding a new area code to the area now served by the 510 area code will provide additional prefixes and new telephone numbers for the 510 customers. The proposed overlay, pending CPUC approval, will allow all customers to keep their current phone numbers, including their area code. To avoid service disruption, the new area code will be added to the 510 area code by December 2018, six months before depletion of prefixes. In December 2018, customers requesting new phone numbers in the 510 geographic area may be assigned a new area code.

The CPUC will be holding local jurisdiction and public meetings on January 17 and February 15, 2017, to inform the local jurisdictions and the public, and to hear concerns about adding a new area code to the 510 area code. More information is available at http://www.cpuc.ca.gov/510areacode.

Area Code Overlay and 10-Digit Local Dialing Approved for the Washington 360, 206, 253 and 425 Area Codes
 
Get ready to change the way you dial your local calls!

What is an area code overlay?
An overlay is the addition of another area code to the same geographic region as an existing area code. An overlay does not require customers to change their existing area code, but does require a new dialing procedure.
 
Who will be affected?
All of western Washington will be affected. The 564 area code overlay will be introduced initially in the existing 360 area code region, and then expanded to the 206, 253, and 425 area codes when those area codes are nearing exhaust.
 
What will be the new dialing procedure?
To complete local calls in western Washington, the new dialing procedure requires callers to dial the area code + the 7-digit telephone number. This means that all calls in the 206, 253, 360, and 425 area codes that are currently dialed with 7 digits will need to be dialed using 10 digits. The same dialing procedure will apply to telephone numbers assigned from the new 564 area code. Calls that are currently local will continue to be local, even though 10-digit dialing will be required.
 
When will the change begin?
Beginning January 28, 2017, you should start using the new dialing procedure whenever you place a call from the 206, 253, 360, and 425 area codes. If you forget and dial 7 digits, your call will still be completed.
 
Beginning July 29, 2017, you must use the new dialing procedure, as described above for all local 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 August 28, 2017, new telephone lines or services may be assigned numbers using the new 564 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 to dial a 7-digit number will need to be reprogrammed to use the new dialing procedure. Some examples are stored telephone numbers in contact lists in phones, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services, etc.  Medical alert devices, safety alarm security systems and gates, ankle monitors or other similar equipment must be programmed to use 10-digit dialing.  Many systems operate on 10-digit dialing by default but some older equipment may still use 7 digits.  Please contact your medical alert or security provider if you don’t know whether your equipment needs to be reprogrammed to accommodate the upcoming change to 10-digit dialing.  You may also want to check your website, business stationery and advertising materials, printed checks, contact information, and personal or pet ID tags to ensure the area code is included.
 
What will remain the same?
  • Your current telephone number 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, even when dialed with 10 digits.
  • You will still need to dial 1+ area code + telephone number to place long-distance calls.
  • You can still dial three digits to reach 911.
  • If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you can still dial three digits.
