Carrier Identification Code (CIC) Administration during a Merger and/or Acquisition
Carrier Identification Codes (CICs) may be transferable from one company to another as long as the CIC
Assignment Guideline (INC Document ATIS-0300050) criteria have been met. This would include presentation of
legal documentation of the merger/acquisition to the CIC Administrator (NANPA), and subsequent verification
proof that all CIC codes have been activated and are currently in use. CIC codes, which have NOT been activated,
are subject to reclamation by the CIC Administrator.
The section entitled “Transfer of CICs”, Paragraph 5.2 of the CIC Assignment Guidelines, which is located at
www.atis.org through the Industry Numbering Committee (INC), summarizes requirements for CIC transfers.
Mandated by the FCC more than two years ago, but not yet in the Guidelines is the limit set on quantity of CICs
available to companies. Only five FGB CICs and two FGD CICs are permitted to be assigned per entity. Transfers
of CICs due to Mergers and/or Acquisitions may result in exceeding the CIC maximums allotted, which would be
permissible as long as the CICs were active (direct FGD trunk access and/or usage, if appropriate, must be current)
at time of transfer.
Access Customer Name Abbreviations (ACNA) (aka Interexchange Access Carrier (IAC) Code)
Under ATIS-0300251.2007 IAC Codes are assigned to identify customers receiving services offered by local
exchange carriers. IAC Codes are used by local exchange carrier customer service centers to identify customers. A
unique three-character alphabetic code (AAA) that identifies the legal company name shall be assigned, as
appropriate, to represent each customer.
Legal documentation is required to substantiate the company name.
