New PA 223 Area Code Overlay for the 717 Area Code

In October 2016, the PA Public Utility Commission voted to implement an area code overlay for the current 717 area code to assist in diminishing number availability. The new overlay will take effect on August 26, 2017. At this time, all calls in the 717/223 area will require dialing 10-digits. Area code usage will be needed even when making calls within the same area code. For your convenience, links to additional information are included below, as well as some frequently asked questions.

An overlay is the addition of another area code to the same geographic area as an existing area code that is requiring relief from diminishing number supply. In Pennsylvania, the 223 area code is being added to the area served by the 717 area code to ensure a continuing supply of phone numbers to those living in the south central PA communities.
By implementing an overlay, current existing 717 phone numbers will not need to change. However, because more than one area code will now serve the same geographic area, it does require you to dial or enter the area code and the 7-digit number for all calls, including calls within the same area code. 10 digit dialing will be required for all calls in the area.
Anyone in the 717 area code is affected, and anyone who receives a phone number from the 223 area code in the future. The 717 area code covers the south central portion of Pennsylvania, including communities such as:

  • Harrisburg
  • Gettysburg
  • York
  • Lancaster
  • Lebanon


The 223 area code will cover the same geographic area as the 717 area code. The map above shows the 717/223 overlay area.

If you have a 717 or 223 phone number, you will need to enter the area code for all calls — including calls within the same area code. To complete local calls from a phone with a 717 or 223 area code, the new calling procedure requires you to enter the area code and 7-digit phone number. 10 digits will be required to make any calls in this area.
Beginning March 4, 2017, if you have a 717 area code, you should start entering the area code for all calls. There will be a grace period so if you just enter 7 digits during the grace period your call will still be completed.

Beginning August 26, 2017, if you have a 717 area code, the new calling procedure will be required for all calls. On or after this date, if you don’t use the new calling procedure, your call won’t be completed and a recording will instruct you to hang up and dial again using the area code.

Beginning September 26, 2017, new phone lines or services may be assigned numbers with the 223 area code. If you have a 223 area code, you must enter the area code and 7-digit phone number on all calls or the call won’t be completed.

Maybe. Each system is different and will need a quick, remote review by a Morefield technician before this can be determined.

In addition to entering the area code and phone number for all calls, you should also complete the following items:

      • Update any pre-programmed 7-digit phone numbers in your mobile device to include the area code, as well as any text or email alert services, and any call forwarding services.
      • Re-program all services and devices that use a 7-digit phone number to include the area code, including automatic dialing equipment. Examples include:
        • Life safety systems and medical monitoring devices
        • Fire or burglar alarm and security systems
        • Security gates
        • Speed dialers
        • Call forwarding settings
        • Fax machines
        • Internet dial-up numbers
        • Voicemail services and similar functions
        • Check your websites, personal and business stationery, advertising materials, personal and business checks, contact information, personal or pet ID tags, and other such items to ensure the area code is included.

The following items will remain the same and won’t change:

  • Your phone number, including current area code
  • The price of a call, coverage area or other rates and services
  • Calls that are considered local now will remain local calls, regardless of the number of digits entered
  • 911 calls aren’t affected, only 3 digits are required
  • If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you’ll still be able to call them by entering just 3 digits
