Telecom Public Notice CRTC 2004-5

  Ottawa, 7 October 2004
  Establishment of two new CISC ad hoc committees for area code relief planning in Alberta area codes 403 and 780
  Reference: 8698-C12-200410879
  With this public notice, the Commission announces the establishment of two CRTC Interconnection Steering Committee ad hoc relief planning committees to examine options for providing relief to area codes 403 and 780 in Alberta. The Commission invites the public and telecommunications service providers to participate in the activities of the ad hoc committees.



On 10 June 2004, the Canadian Numbering Administrator (CNA) published the results of the latest General Numbering Resource Utilization Forecast (G-NRUF) for the various area codes in Canada. The results of the latest G-NRUF indicated that area code 403 was projected to exhaust in September 2009, and area code 780 was projected to exhaust in November 2011. To this end, there is a need to begin a separate area code relief planning process for both area codes, which is being initiated through the release of this public notice.



In Approval of revised Canadian NPA Relief Planning Guidelines, Decision CRTC 2001-607,26 September 2001, the Commission established revised guidelines for the relief of area codes prior to their exhaust. The Canadian NPA Relief Planning Guidelines (the Guidelines), as amended from time to time with the Commission's approval, provide the framework to be followed for addressing area code exhaust in Canada. The Guidelines establish a step-by-step process to be followed by the CNA and the relief planning committee, and also identify certain actions that are left to the Commission to address.


In accordance with the Commission-approved Guidelines, area code relief planning will be conducted in a public manner through the establishment of ad hoc committees of the CRTC Interconnection Steering Committee (CISC), called relief planning committees (RPCs), in order to increase public awareness and participation. The CNA, in its function as numbering plan area (NPA) relief planning co-ordinator, acts as a chair of these RPCs.


The NPA 403 and NPA 780 RPCs are each responsible for developing a relief planning document which describes all options that might reasonably be pursued to implement relief for area codes 403 and 780. The benefits and drawbacks of each relief option described will be clearly identified by the RPC and documented in an Initial Planning Document. Each of the Initial Planning Documents will then be forwarded to the Commission via the CISC process for inclusion in a public process, where the Commission will seek comments on the appropriate method by which relief will be implemented. The Commission will then render its decision.


Although area code 403 is projected to exhaust two years earlier than area code 780, the RPCs may, if they believe it to be in the best interest of the relief planning process, consider the benefits of jointly addressing the relief solutions for both area codes during their deliberations, since both area codes are located in Alberta.


The scope of relief planning activities is limited to the consideration of solutions related to the introduction of new numbering resources within a geographical area. Since area code relief planning does not impact local and long distance calling areas or rates, these issues are outside the scope of the processes described in this public notice.


The first meeting of the NPA 403 RPC is scheduled to take place on 22 November 2004 and 23 November 2004 in Calgary, Alberta. The first meeting of the NPA 780 RPC is scheduled to take place on 25 November 2004 and 26 November 2004, in Edmonton, Alberta. The CNA will announce the specific locations, and times of these initial meetings and make available all related documentation, including the Initial Planning Document and a schedule of future meetings, to all interested parties. In addition, information concerning area code 403 and area code 780 relief planning activities will be available through the office of the CNA via or by calling the CNA at (613) 563-7242.


Once the Commission has considered all public comments and has made a determination on a relief method and date for these area codes, the RPCs will be called upon to develop a proposed NPA relief implementation plans for area code 403 and area code 780. The relief implementation plans will be forwarded to the Commission for approval, via the CISC process. If approved, all telecommunications service providers (TSPs) using, or intending to use, numbering resources in area code 403 and/or area code 780 will be required to execute the plans.


In preparation for these relief planning activities, the CNA should ensure that all central office (CO) codes in area codes 403 and 780 are accounted for, and that all records for these area codes, including local dial plans, are up to date. Where local dial plans have not yet been provided to the CNA, TSPs are required to submit their dial plans within 30 calendar days of this public notice.


In addition, the CNA should ensure that Part 4 forms have been received for all assigned CO codes in these area codes as per the timelines set out in the Canadian Central Office Code (NXX) Assignment Guidelines. The CNA should initiate reclamation of any NXX assigned to any carrier that has not filed the appropriate documentation and that has not received an extension as per the guidelines.



Parties wishing to participate in the activities of the NPA 403 RPC and/or the NPA 780 RPC must notify the Commission of their intention to do so by contacting the Secretary General by mail at CRTC, Ottawa, Ontario, K1A 0N2; by fax at (819) 994-0218; or by e-mail at, by 18 October 2004. Interested parties are to indicate in the notice their e-mail address where available. If parties do not have access to the Internet, they are to indicate in their notice whether they wish to receive a disk version of hard copy filings.


The Commission will issue, as soon as possible after the registration date, a complete list of parties and their mailing addresses (including their e-mail address, if available), identifying parties who wish to receive disk versions.
