CISC Canadian Steering Committee on Numbering – Consensus report CNRE109A – Canadian Non-geographic Code Assignment Guideline

  1. On 7 November 2014, the Canadian Steering Committee on Numbering (CSCN) of the CRTC Interconnection Steering Committee (CISC) submitted the following consensus report for Commission approval:
    • Canadian Non-geographic Code Assignment Guideline (CNRE109A)
  2. In its report, the CSCN proposed a new guideline related to the assignment of the 622, 633, 644, 655, 677, and 688 non-geographic numbering plan area (NPA) codes. The proposed guideline describes and specifies procedures for the assignment and administration of telephone numbers for non-geographic telecommunications services that carriers provide to customers in Canada.
  3. The CSCN submitted that the proposed guideline was the result of work that it undertook to address issues created by the increased demand for telephone numbers related to technologies such as machine-to-machine applications. The CSCN stated that these technologies have placed pressure on the supply of telephone numbers used for purposes other than traditional telephony applications.
  4. The CSCN stated that NPAs 622, 633, 644, 655, 677, and 688 are currently reserved for relief for the Canadian NPA 600, which has no forecasted growth. The CSCN also stated that industry projections indicate that the continued use of geographic telephone numbers for non-geographic applications could result in the premature exhaustion of some geographic NPAs.
  5. The consensus report can be found in the “Reports” section of the CSCN page, which is available in the CISC section of the Commission’s website at
  6. The Commission considers that the CSCN’s proposal to assign NPAs 622, 633, 644, 655, 677, and 688 to applications that involve the exchange of traffic between carriers that does not require the use of geographic telephone numbers, as described in the proposed guideline, will help ensure an effective and efficient use of geographic telephone numbers.
  7. The Commission has reviewed and approves the above-noted consensus report and the proposed guideline.
