Maps for Boundary Change Cases
ILECs can modify a telephone exchange boundary by submitting an application to the PUCO. The boundary change process is governed by Ohio Administrative Code 4901:1-6-32. The quadrangle maps that are linked from this page serve as the official source/documentation of ILEC service areas per paragraph (A) of 4906:1-6-32. A list of open, closed, and archived boundary change cases is available on the PUCO docketing website.
