RE:  Area Codes 306/639 End of Jeopardy Situation

Dear Kelly T. Walsh:

By letter dated 21 October 2020, the Canadian Numbering Administrator (CNA) advised CRTC staff that in accordance with the October 2020 Jeopardy Numbering Resource Utilization Forecast (J-NRUF) the projected exhaust date (PED) for area codes 306/639 has moved out of a jeopardy condition. The CNA advised that the PED is now May 2022 (seven months after the relief date) with assignment restrictions and April 2022 (six months after the relief date) without assignment restrictions. Based on the PED with assignment restrictions, area codes 306/639 are only one month away from moving back into a jeopardy condition.

Given that area codes 306/639 are no longer in a jeopardy condition, the CNA has provided several recommendations for CRTC staff on how the CNA should proceed. These recommendations would require the CNA to:

  1. Stop enforcing the area code 306/639 Jeopardy Condition Plan located in Section 10 in the Commission approved NPA 306/639 Planning Document;
  2. Conduct area code 306/639 special numbering resource utilization forecasts (S-NRUF) at the NPA level of detail in January 2021 and April 2021; and
  3. Freeze all central office code assignments in area code 306/639 based the October 2020 J-NRUF carrier submissions.

Commission staff notes that the jeopardy condition plan is included in the Commission approved Relief Implementation Plan for area codes 306/639. This plan is invoked by the CNA when certain conditions relative to the PED and the relief implementation date occur putting these area codes into a jeopardy condition. When those conditions change such that the area codes are no longer in a jeopardy condition, the jeopardy condition plan is no longer required.

Commission staff agrees with the CNA’s assessment that the area code 306/639 complex is no longer in a jeopardy condition. However, as the area code 306/639 complex is on the cusp of falling back into a jeopardy condition, some degree of prudence is required in CO code assignments until relief has been implemented. In order to address this complexity, the CNA has proposed to follow the specific measures set out above. Commission staff agrees with the measures proposed by the CNA.
