Canadian Steering Committee on Numbering


The Canadian Steering Committee on Numbering (CSCN) is a Working Group of the CISC and addresses numbering issues that fall under the jurisdiction of the CRTC. The CSCN establishes numbering administration guidelines which the Canadian Numbering Administrator (CNA) follows to provide numbering administration functions for the Canadian telecommunications industry. Leidos Canada, Inc. currently performs the CNA role under contract to the Canadian Numbering Administration Consortium (CNAC), which is authorized by the CRTC to hire a contractor to perform the CNA function. The CNA works cooperatively with the North American Numbering Plan Administrator (NANPA) to ensure effective and efficient use of North American Numbering Plan (NANP) resources.

The menu on the left side of this page provides access to various types of CSCN, CNA, CRTC and other documents related to numbering administration.
