NOTICE REGARDING TARIFFS FOR REGULATED SERVICES For your convenience, copies of tariffs for services regulated by the Michigan Public Service Commission (MPSC) have been posted on this website on behalf of certain telecommunications service providers operating in the State of Michigan. These tariffs are on file with the MPSC and the filed tariffs are the official reference for tariff information. Although precautions have been taken to ensure that tariffs on this website are identical to the filed versions, undetected production errors may cause discrepancies to occur. In the case of any discrepancies, the official tariffs on file with the MPSC will prevail.
