9YY NXX Codes


9YY NXX numbers are used to access premium services offered by a carrier’s subscriber. When these services are accessed, the calling party pays for call setup and the specific services associated with the 9YY call, and the cost of calls to these services is normally billed to the calling party. The intended services to be supplied by 9YY subscribers are information services.

9YY NXX numbers are in the format 9YY-NXX-XXXX, where the prefix (NXX) is assigned to the carrier, and the line number (XXXX) indicates the particular premium service. The 9YY NXX Code Holder assigns the individual numbers to their subscriber that offers the premium service.

To access the information service provider, the calling party dials (1)+9YY-NXX-XXXX. The Local Exchange Carrier (LEC) will perform a 6-digit translation of the 9YY NXX portion of a 9YY-NXX-XXXX number in order to identify the carrier for call routing. The carrier will route the call to the information service provider.

9YY NXX codes are assigned to 9YY service providers according to the guidelines developed by the ATIS-sponsored Industry Numbering Committee.  9YY NXX service is not portable; that is, the identity of the service provider is embedded in the number.

9YY NXX Codes are assigned according to the Industry Numbering Committee (INC) 9YY NXX Code Assignment Guidelines, as accepted or modified by the Canadian Steering Committee on Numbering. If you wish to apply for an assignment, fill out the application form included in the assignment guidelines, and return it to the Canadian Numbering Administrator.

The most recent version of the Commission-approved Canadian Adjunct to the Industry Numbering Committee (INC) 9YY NXX Code Assignment Guidelines is available here.
