Telecom Public Notice CRTC 2007-1

  Ottawa, 11 January 2007

Relief planning for numbering plan areas 403 and 780 in Alberta

  Reference: 8698-C12-200700337 and 8698-C12-200410879



In Establishment of two new CISC ad hoc committees for area code relief planning in Alberta area codes 403 and 780, Telecom Public Notice CRTC 2004-5, 7 October 2004 (Public Notice 2004-5), the Commission established two CRTC Interconnection Steering Committee ad hoc relief planning committees (RPCs) to develop relief planning options for the numbering plan areas (NPAs) 403 and 780 and invited interested parties to participate in the committee's public meetings.


The Canadian Numbering Administrator's (CNA) latest Relief Planning Numbering Resource Utilization Forecast for NPA 403 and 780, which assessed the impact of the planned introduction of wireless number portability, showed that the projected exhaust date for NPA 403 would arrive 17 months earlier, in October 2009. It also showed that the projected exhaust date for NPA 780 would arrive 27 months earlier, in November 2010.


According to the Canadian NPA Relief Planning Guidelines (the Relief Guidelines), a jeopardy condition is declared when the Commission has not established a relief method and date, and the CNA projects an NPA will exhaust within 36 months. In a 2 October 2006 letter to the CNA, Commission staff noted that NPA 403 in Alberta was in a jeopardy condition and instructed the CNA to immediately implement and follow the special conservation procedures described in paragraph 8.3 of the Relief Guidelines.


On 5 October 2006 the NPA 403 and NPA 780 RPCs met and agreed to merge the two RPCs into one RPC and to produce a single initial relief planning document for both NPAs.


On 8 November 2006, pursuant to Public Notice 2004-5, the RPC filed an initial relief planning document1 which describes all options that might reasonably be pursued to implement code relief for NPAs 403 and 780 and provides recommendations.


The 403/780 RPC's initial relief planning document includes options such as:

- the Calgary extended area service (EAS) and the Edmonton EAS both retaining their NPAs (NPA 403 and NPA 780 respectively), and the rest of Alberta would be re-assigned to a new NPA;


- a concentrated overlay2 of a new NPA on the Calgary EAS portion of NPA 403, and the Outside Calgary EAS would continue to grow with the remaining CO codes in NPA 403;


- a concentrated overlay of a new NPA on the Edmonton EAS portion of NPA 780, and the Outside Edmonton EAS would continue to grow with the remaining CO codes in NPA 780;


- the Calgary and Edmonton EAS would grow with NPA 403 and NPA 780 respectively, and the rest of Alberta would receive a concentrated overlay of a single new NPA;


- a distributed overlay of a single new NPA on NPAs 403 and 780; and


- distributed overlays of separate new NPAs on NPAs 403 and 780 at the same time.


The 403/780 RPC's initial relief document includes, among others, the following recommendations:

- implementing a distributed overlay of a single new NPA on NPAs 403 and 780;


- implementing relief for NPAs 403 and 780 in a single phase regardless of the relief option chosen;


- allowing any 7-digit local dialing that currently exists from Lloydminster and Marshall in NPA 306 (Saskatchewan) into NPA 780 to continue after NPA 780 relief. The rationale for this recommendation is explained in more detail in section 5 of the initial planning document;


- setting aside NPAs 587 and 825 for future NPA assignments in Alberta; one of these NPAs would be assigned for the distributed overlay recommended above. The rationale for this recommendation is explained in more detail in section 5 of the initial planning document; and


- revoking the jeopardy condition in NPA 403 60 days prior to NPA 403 relief implementation. This is explained in more detail in section 11 (Jeopardy Contingency Plan) of the initial planning document. Additionally, if a jeopardy condition is declared in NPA 780 then it would be revoked 60 days prior to implementation of joint NPA 403/780 relief.


The RPC noted that if customers in the Calgary and Edmonton areas preferred separate overlay NPAs for NPAs 403 and 780, its second choice of preferred relief options was Joint 3-b (Distributed Overlays of separate new NPAs on NPAs 403 and 780 at the same time).

Issues to be addressed in this proceeding


The Commission invites comments on:

- the options and recommendations developed by the RPC and described in the initial relief planning document;


- the effects of the various relief options developed by the RPC on consumers, telecommunications service providers and all other affected parties;


- the most appropriate relief option(s) to alleviate the exhaust of area codes 403 and 780;


- an appropriate relief date for area codes 403 and 780; and


- any other matter that parties consider relevant to the implementation of relief measures.


Parties wishing to examine other documents relating to the activities of the NPA 403 and 780 RPC can do so by accessing the CNA's website at and or by contacting the office of the CNA at 613-563-7242 ext. 317.

2  An overlay occurs when a new NPA is distributed over the same geographic area as an existing NPA. This method necessitates 10‑digit dialing of local calls between the old and new NPAs coincident with the implementation of NXX codes in the new NPA. A concentrated overlay occurs as a result of a new NPA being distributed over part of an existing NPA due to the concentration of demand for new telephone numbers in one section of an existing NPA.
