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.

Area Code Overlay Approved for the North Carolina 336 Area Code

To ensure a continuing supply of telephone numbers, the new 743 area code will be added to the area served by 336. This is known as an area code overlay. 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 (743) to the same geographic region as an existing area code (336). An overlay does not require customers to change their existing area code or telephone number but it will require ALL callers to dial 10 digits for local area calls.
 
Who will be affected?
The 336 area code generally covers the Piedmont area and includes the cities of High Point, North Wilkesboro, Winston-Salem, Greensboro and Asheboro. The new 743 area code will serve the same geographic area currently served by the existing 336 area code. 
 
What will be the new dialing procedure?
To complete local calls, the new dialing procedure requires callers to dial area code + telephone number. This means that all calls in the 336 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number.  The same dialing procedure will apply to telephone numbers assigned to the new 743 area code.  However, the price of local calls made today by dialing 7 digits will not change when 10 digits are dialed for the new overlay area code. Long distance dialing will not change but will still require dialing 1 + area code + telephone number.
 
When will the change begin?
Effective October 24, 2015, you should begin using the new dialing procedures whenever you place a call from the 336 area code. If you forget and dial just seven digits, there will be a temporary grace period and your call will still be completed.
 
However, beginning April 23, 2016, use of the new dialing procedures will be mandatory. 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 May 23, 2016, new telephone lines or services may be assigned numbers using the new 743 area code. Existing numbers will not be changed.
 
What will you need to do?
REMEMBERIn 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, PBXs, mobile phone contact lists, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, call forwarding settings, voicemail services, etc. You may also want to check your business stationery, website, or advertising materials, and your pet’s or your personal 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.
  • If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you will still dial
these codes with just three digits.

Public Participation Meetings Regarding Changes in the California 213 and 323 Area Codes

Schedule and Locations of Public and Local Jurisdiction Meetings

 
IMPORTANT: PUBLIC PARTICIPATION MEETINGS REGARDING CHANGES IN THE 213 and 323 AREA CODES
 
The California Public Utilities Commission will begin a process to introduce the 213 area code to the area that is now served by the 323 area code. This is being done because the 323 area code is expected to use up all the available prefixes by March 2018. Adding the 213 area code to the 323 area will provide additional prefixes and ensure new telephone numbers are available for the 323 area code customers. It is customary to introduce another area code at least six months before the existing area code will use up all of its prefixes. Therefore, the 213 will be added to the 323 by November 2017.
 
The CPUC will be holding public meetings on September 8, 9, and 10, 2015 to inform the public about changes in the 213 and 323 area codes, and to hear concerns about the area code changes. More information is available at http://www.cpuc.ca.gov/323areacode.

Existing Area Code 786 Now Expanding to Serve Subscribers in the Keys area of Florida
All Customers to start dialing 10-Digits starting April 18, 2015

 
To ensure a continuing supply of new telephone numbers in the Florida Keys served by area code 305, the Florida Public Service Commission has approved the expansion of the 786 area code to the Keys, so the 786 overlay will cover the same geographical region as the existing 305 area code.
 
What is an area code overlay?
An overlay is the addition of another area code (786) to the same geographic region as existing area code (305). The expansion of the 786 overlay does not require you to change your existing area code or phone number, but it does require you to change how you dial your local calls. Because two area codes will serve the same geographic area, you will need to dial the area code and phone number on all local calls within and between the 305 and 786 area codes starting April 18, 2015.
 
Who will be affected and when will the change begin?
The 786 overlay will be expanded into Monroe County and the 305 Florida Keys, which includes communities such as Big Pine Key, Islamorada, Key Colony Beach, Key Largo, Key West, Layton, Marathon, North Key Largo and Sugar Loaf Shores.
 
Beginning April 18, 2015, all local calls within and between the 305 and 786 area codes throughout the 305 area, including the Keys, will require 10-digit dialing.  A permissive 10-digit dialing period has been in place since August 1, 2001 so you don’t have to wait until April 18, 2015 to start dialing ten digits on all local calls. 
 
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 number will need to be reprogrammed to dial the area code and phone number. Some examples are life safety systems and medical monitoring devices, PBXs and fax machines, Internet dial-up numbers, alarm and security systems or gates, speed dialers, mobile phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to check your website, business stationery, advertising materials, personal and business checks, contact information and your personal or pet ID tags to ensure the area code is included in your telephone number. 
 
What will remain the same?
  • Your telephone number, including current area code, will not change.
  • What is a local call now will remain a local call.
  • The price of a call, coverage area, or other rates and services will not change due to the expansion of the overlay.
  • You can still dial just three digits to reach 911.
