570 was split from area code 717 on December 5, 1998. It was the first new Pennsylvania area code created outside of Philadelphia and Pittsburgh since the implementation of the area code system.
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. The implementation of 272 means that the only parts of Pennsylvania that haven't been overlaid are the Susquehanna Valley (717) and west-central Pennsylvania (814).
