555 Line Numbers

Originally 555 line numbers (LNs) were a unique non-geographic resource assigned on a national or non-national NPA-related basis for public information services. Entities that could be assigned these resources included individuals, companies and Carriers.

All 555 LN assignments made in Canada have been reclaimed except 555-1212 which is used for long distance directory assistance and 555 LNs set aside for use by the television/movie industry (555-0100 to 555-0199). At this time, no additional 555 LN assignments will be made.

The current CRTC approved Canadian Adjunct to the 555 NXX Line Number Reference Document can be found on the CRTC website.
