<P> In 2009, it was projected that 570 would run out of numbers in the third quarter of 2011 . The Pennsylvania Public Utility Commission considered four options--an overlay plan and three split plans . All but one of the splits would have left Scranton and Wilkes - Barre, the two largest cities in the 570 territory, within the same area code . On July 15, 2010, the PUC decided the new area code, 272, would be implemented as an overlay. 272 officially entered service on March 28, 2013 . Ten - digit dialing became mandatory in northeastern Pennsylvania on September 21, 2013 . </P> <P> In 2015 there were 11 available prefixes in 570 . By 2017, 570 had been completely exhausted; only one prefix was left in February, and that prefix was exhausted by May . </P> <P> Locations are approximate .
