According to the FCC’s Office of Inspector General (“OIG”) in its semi-annual report to Congress, more than 1,000 telephone companies may not have filed an annual Form 499-A as required by FCC rules. The FCC hired an independent auditing firm to gather data from state commissions and compare them to federal records. In September 2009, OIG issued 49 letters to potential non-filers asking whether they were required to file FCC Form 499-A. OIG expects to provide further information about the audit and its results in its next report to Congress.
