All Customers with a Pennsylvania 717 Area Code Must Dial Area Code + Telephone Number For all Local Calls Beginning August 26, 2017


What is the new dialing procedure? 

To complete calls within the 717 area code region, the new dialing procedure requires callers to dial area code + telephone number. This means that all calls in the 717 area code that are currently dialed with seven digits will need to be dialed using ten digits, that is, the area code + telephone number. The same dialing procedure will apply to telephone numbers assigned to the new 223 area code.

Who will be affected?

The 717 area code covers the south-central portion of the state serving communities such as Gettysburg, Harrisburg, Lancaster, Lebanon, and York. The new 223 area code will serve the same geographic area currently served by the existing 717 area code.

Why is the change necessary?

To ensure a continuing supply of telephone numbers, the new 223 area code will be added to the area served by 717. Since two area codes will now serve the same geographic region, the area code must be used when dialing any telephone number - including calls within the same area code.

Beginning September 26, 2017, new customers in the 717 geographic area may be assigned telephone numbers with the new 223 area code. All calls made within and between area codes 717 and 223 must be placed using the 10-digit telephone number (717 or 223 plus the 7-digit telephone number).

When will the change become mandatory?

Starting August 26, 2017, you must use the new dialing procedure for all local calls.  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.

However, all customers should begin using the new dialing procedure before August 26, 2017.

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 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 wireless 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 your personal or pet ID tags to ensure the area code is included.

What will remain the same?
