N11 Codes Description

Service codes, commonly called N11 codes because of their format, are used to provide three-digit dialling access special services. The most common assignments of N11 codes, in Canada, are as follows:

N11 Code	Services
211	Public Information and Referral Services
311	Non-emergency Municipal Government Services
411	Local Directory Assistance
511	Weather and Traveler Information Services
611	Repair Service
711	Message Relay Service (MRS)
811	Non-urgent Health Care Telephone Triage Service
911	Emergency

In Decision CRTC 2001-475, Allocation of three-digit dialling for public information and referral services, the Commission determined that the allocation of unused N11 codes should be based upon the following guideline:

• there must be a compelling need for three-digit access that cannot be satisfied by other dialling arrangements or it is demonstrated that existing dialling arrangements are not suitable for accessing the needed services;
• the assignment of an unused N11 code should be to a service or services rather than a specific organization;
• the provision of N11 dialling is to be based on a need to serve the broad public interest (including providing access to the telephone network to disadvantaged individuals or groups);
• the N11 dialling should not confer a competitive advantage on the service provider(s) reached by this number;
• the services to be provided through N11 dialling are to be widely available geographically and on a full-time or extended-time basis; and
• where possible, the N11 allocation to a service does not conflict with NANP and is in keeping with the CSCN guideline for N11, which state that the application of N11 should be uniform and consistent throughout the NANP area to the maximum extent practical, and the unassigned N11 codes should be designated primarily for basic, or adjunct-to-basic, telecommunications services of a universal social value rather than for commercial use by certain industry segments.
