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.

New Area Code Added to Pennsylvania 570 Region

Get ready to change the way you dial your calls!

To ensure a continuing supply of telephone numbers, the new 272 area code will be added to the area served by 570. This is known as an area code overlay.

What’s an area code overlay?                                                                                          
An overlay adds another area code (272) to the same geographic region as an existing area code (570). An overlay does not require customers to change their existing area code or telephone number.

Who is affected?
The 570 area code covers the northeastern portion of the state serving communities such as Scranton, Williamsport and Wilkes-Barre.

What is the new dialing procedure?
To complete local calls within the home area code, begin to dial the area code + telephone number. This means that all calls in the 570 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number, for example, 570-555-1212.

When does the change begin?
Effective immediately you can begin using 10 digits whenever you place a local call from the 570 area code. If you forget and dial just seven digits, your call will be completed until September 21, 2013.

Starting September 21, 2013 you must use 10-digit calling for your call to complete. If you don’t, your call won’t be completed and a recording will instruct you to hang up and dial again.

As of October 21, 2013, new customers in the 570 geographical area may be assigned telephone numbers with the 272 area code. What is a local call now will remain a local call regardless of the number of digits dialed and whether area code is 272 or 570.

What do I need to do?
In addition to changing your dialing procedure, reprogram your automatic dialing equipment, such as, life safety systems, telephone sets, PBXs, fax machines, alarm and security systems, gates, speed dialers, call forwarding settings, voicemail services to 10-digit dialing from 7-digit. Revise your business stationery or advertising materials to ensure the area code is included.

What will remain the same?
• Your telephone number, including the current area code.
Your price for your calls, coverage area, and other rates and services. What is a local call now will remain a local call regardless of the number of digits dialed.
• You will continue to dial 1+ area code + telephone number for local and long distance calls made outside the home area codes of 272 and 570.
• Emergency service remains just three digits, 911.
• If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you can still use these codes with just three digits.
