10-digit Dialing to Begin Soon

PUC Reminds Central PA Residents & Businesses of Upcoming Switch to 10-Digit Dialing in ‘717’ Area Code

July 11, 2017

HARRISBURG – The Pennsylvania Public Utility Commission (PUC) today reminded residents and businesses across Central Pennsylvania served by the 717 area code of the upcoming switch to 10-digit dialing for all local calls – in preparation for the activation of a new “overlay” area code, which will serve the entire region.

According to the implementation schedule for the “223” overlay area code, mandatory 10-digit dialing for all local calls will begin on Aug. 26, 2017. Starting on that date, if callers only dial a seven-digit number, they will reach a recorded announcement instructing them to hang up and redial the number using the area code plus the seven-digit number.

For the past several months, telephone callers in the 16-county 717 service area have been encouraged to voluntarily use 10-digit dialing (717 + the full local telephone number). The new 223 overlay area was approved based on forecasts that the remaining supply of available telephone numbers in the 717 area code was close to exhaustion.
