History and Evolution of Area Code 717
Area code 717 stands as one of the original North American area codes established in 1947. Initially, it covered a vast swathe of eastern Pennsylvania, stretching from the Maryland border north to the New York and New Jersey borders. Imagine a time when this single area code served a region encompassing cities like Harrisburg, Lancaster, York, Scranton, and Wilkes-Barre! This made 717 one of the largest area codes east of the Mississippi River that didn't cover an entire state.
As the demand for telephone numbers grew, particularly with the rise of cell phones, pagers, and fax machines, the 717 area code faced the risk of exhaustion. To address this, the northern portion of the original 717 territory, including Scranton and Wilkes-Barre, was assigned the new area code 570 in 1998. This split helped manage the increasing demand for phone numbers and ensured continued efficient service. Interestingly, a small adjustment occurred in 1994, shifting a few towns in eastern Lancaster and western Chester counties from the prospective 610 area code to 717. This was driven by non-Bell companies aiming to consolidate their eastern Pennsylvania subscriber base.
Even after the 1998 split, the remaining 717 area code continued to experience growth in phone number demand. By 2010, projections indicated potential exhaustion by the second quarter of 2018. To prevent disruption and allow residents to keep their existing numbers, the Pennsylvania Public Utility Commission (PUC) opted for an overlay solution. In 2017, area code 223 was introduced as an overlay to 717. This means both area codes serve the same geographic region, making 10-digit dialing mandatory for all calls within the area. You might be interested to know that this overlay decision was largely supported by public feedback, as it minimized the inconvenience and cost associated with changing phone numbers.
