Area codes 814 and 582 are telephone area codes in the North American Numbering Plan (NANP) for the northwestern and central portions of the Commonwealth of Pennsylvania. Cities served by the area code include Altoona, Bradford, DuBois, Erie, Meadville, Oil City, Titusville, Johnstown, St. Marys, and Warren as well as the boroughs of State College, Brockway, Clearfield, Huntingdon, Mount Union, Bedford, Clarion, Punxsutawney, Tyrone, Ebensburg, Coudersport, Ridgway and Brookville. Area code 814 is the original area code assigned to the service area in 1947, and area code 582 is an additional code for the area to form an overlay plan with a starting date of October 3, 2020.
Area code 814 is one of the original numbering plan area (NPA) codes established in 1947. Its geographic area is the largest in the state. It is the only one of Pennsylvania's original four NPAs that still has its original boundaries, and is one of the few original area codes (not counting those serving an entire state) that have never been split or overlaid as of 2020. With area code 717 having been overlaid with area code 223 in 2017, as of 2020, 814 is the only portion of Pennsylvania where seven-digit dialing is still possible. The largest cities in the area are Johnstown, Altoona, State College and Erie; otherwise this region is largely rural.
On May 14, 2020, the Pennsylvania Public Utility Commission decided to assign area code 582 in an overlay plan to the existing 814 territory, in the face of projections that 814 would exhaust in late 2022. It will enter service on October 3, 2020. On that date, a permissive dialing period will begin, during which both seven- and ten-digit calls can complete. Ten-digit dialing is scheduled to be mandatory on April 3, 2021 for all calls in the region. The first 582 numbers will be available for assignment on May 1, 2021. The addition of 582 will eliminate the last area of seven-digit dialing in the Commonwealth.
When numbering pool exhaustion became a threat in the 2000s, the Pennsylvania Public Utility Commission (PUC) approved a numbering plan split in December 2009, that would have assigned area code 582 to most of the northwestern portion of the 814 territory, including Erie, in 2012. Under the proposed split, area code 582 would have served Erie, Crawford, Warren, Venango, Forest, Clarion, Jefferson, Elk, and McKean counties, while the remaining counties would've remained in 814. Parts of Armstrong, Clearfield, Indiana, and Mercer counties also were to be switched to 582. Under the plan, most of Clearfield and Indiana counties would have retained 814; most of Armstrong and Mercer counties would continue in area code 724. This would have been the first split in the NANP since 2007.
After the decision, a grassroots movement circulated an online petition to request the commission to cancel the action in favor of an overlay plan. The telecommunications industry also supported implementing 582 as an overlay.
By February 27, 2012, the projected exhaustion date for 814 was changed to the second quarter of 2018. On April 26, 2012 the PUC voted 5–0 to dismiss the plans to split 814 and revoke the implementation schedule. At the time, projections suggested that 814 would be exhausted around 2021. The split never came to be, and eventually the PUC changed their plans from a split to an overlay.
