The March 1, 2017 filing deadline for submitting FCC Form 477 data current as of December 31, 2016 has been extended due to technical difficulties with the form’s filing interface. The new filing deadline is not yet known and will be announced in a separate public notice from the FCC’s Wireline Competition Bureau. Form 477 must be filed by all facilities-based providers of broadband, local telephone, interconnected VoIP, and mobile telephony services.
