§  61.1   Purpose and application.

   (a) The purpose of this part is to prescribe the framework for the
   initial establishment of and subsequent revisions to tariff
   publications.

   (b) Tariff publications filed with the Commission must conform to the
   rules in this part and with Commission rules regarding the payment of
   statutory charges (see subpart G of part 1 of this title) and the use
   of FCC Registration Numbers (FRNs) (see subpart W of part 1 of this
   title). Failure to comply with any provisions of these rules may be
   grounds for rejection of the non-complying publication, a determination
   that it is unlawful or other action. Where an FRN has been omitted from
   a cover letter or transmittal accompanying a tariff publication filed
   under this part or the FRN included in that letter is invalid, the
   submitting carrier or carrier representative shall have ten (10)
   business days from the date of filing to amend the cover letter or
   transmittal to include a valid FRN. If within that ten (10) business
   day period, the carrier or carrier representative amends the cover
   letter or transmittal to include a valid FRN, that FRN shall be deemed
   to have been included in the letter as of its original filing date. If,
   after the expiration of the ten (10) business day period, the cover
   letter or transmittal has not been amended to include a valid FRN, the
   related tariff publication may be rejected if it has not yet become
   effective, declared unlawful if it has become effective, or subject to
   other action.

   (c) No carrier required to file tariffs may provide any interstate or
   foreign communication service until every tariff publication for such
   communication service is on file with the Commission and in effect.
