On May 14, 2020, the Pennsylvania Public Utility Commission approved area code 582 for an all-service overlay, in the face of projections that 814 would exhaust in late 2022.
[2] The proposed new numbering plan area would have served Erie, Crawford, Warren, Venango, Forest, Clarion, Jefferson, Elk, McKean counties and parts of Armstrong, Clearfield, Indiana, and Mercer.
After the decision, a grassroots movement circulated an online petition to request the commission to cancel the action in favor of an overlay plan,[3] a change also supported by the telecommunication industry.
[4] By February 27, 2012, the projected exhaustion date for 814 was changed to the second quarter of 2018,[5] causing the PUC in a 5–0 vote on April 26, 2012 to dismiss the split plan and implementation schedule.
