PUC Announces Ten-Digit Dialing Procedures Begin in 570 Area Code

HARRISBURG –   The Pennsylvania Public Utility Commission (PUC) today announced that the permissive dialing period has commenced for residential and business customers within the existing 570 area code.

During the permissive dialing period, callers can begin using 10 digits each time they place a call from the 570 area code.  However, if a caller dials just seven digits, the call will still be completed.  Beginning Sept. 21, 2013, the mandatory dialing period commences in the 570 area code.  During the mandatory dialing period, all calls must be made using the area code plus the seven-digit number.  If only the seven-digit telephone number is dialed, customers will reach a recorded announcement stating they must hang up and redial the number using the area code plus the seven-digit number. This recording will be available permanently. 

On July 15, 2010, the Commission approved an overlay plan for the 570 code, after consideration of public input and area code relief options.  An overlay plan means that once the existing telephone numbers in the 570 area code are exhausted, new telephone services in that geographic region will be assigned telephone numbers out of the new area code, which has been designated as 272.   

To ensure a continuing supply of telephone numbers, the new 272 area code will be added to the 570 area code region, which generally covers the northeastern portion of the state and serves communities such as Scranton, Williamsport and Wilkes-Barre.   Beginning Oct. 21, 2013, customers in the 570 area code region requesting new service, an additional line, or in some cases, moving their service may be assigned a number in the new 272 area code.

When introducing a new area code, there is an adjustment period commonly known as a permissive dialing period, which commences approximately six months before the new area code becomes effective.  During the permissive dialing period, customers may reach numbers in the current area code by either dialing ten or seven digits.  At the end of the permissive period, all calls require ten-digit dialing to be completed.        

Important facts for businesses and residents to remember during the transition:

  • Your telephone number, including current area code, will not change.
  • You will need to dial area code + telephone number for all local calls. 
  • You will continue to dial 1+ area code + telephone number for all long distance calls.
  • 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 overlay.
  • 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

Customers should identify their telephone number as a ten digit number (area code + 7 digit telephone number), and include the area code when giving the number to their friends, family, business associates and customers, etc. For more information, consumers may contact their telephone service provider or the PUC at 1-800-692-7380.
