Reminder: Carrier Identification Code Reports Due July 31

Failure to submit the required semi-annual reports may result in CIC reclamation by NANPA.

The semi-annual Carrier Identification Code (CIC) Entity Access and Usage reports covering the period from January 1 through June 30, 2023, are due to the North American Numbering Plan Administration (NANPA) CIC Administrator by July 31, 2023. These reports are the sole tool used by NANPA to confirm if a CIC is being used in accordance with the CIC Assignment Guidelines or to determine if a CIC is subject to reclamation by NANPA.

For purposes of usage and reporting, CICs are assigned as Direct Trunk Access Feature Group B or D (FG B / FG D) or Switchless Reseller. Companies assigned Direct Trunk Access CICs must have trunk access with a facilities based LEC. The trunk access must be reported to NANPA by both the CIC assignee and the facilities based LEC from which the CIC assignee purchases access.

Holders of Switchless Reseller CICs must report the underlying carrier with which the CIC has FG D usage.
CIC reminders:

  • NANPA may initiate CIC reclamation if the required reports are not submitted.
  • Make sure the CIC reports are accurate before submission as information provided is considered certified.
  • CICs must be used in the manner they were requested and assigned within the CIC guidelines.
  • Verify your company’s CIC contact on file with NANPA is current and accurate. If not, updates should be filed with NANPA.

For more information about the required reporting and how JSI’s CIC Management Service can help you better manage your CICs in the future, contact Lisa Cover in JSI’s Maryland office at 301-459-7590.
