CANADIAN PLANT TEST PREFIXES
by Www.artofhacking.com Staff.
Updated 2004/09/18

In Canada, every area code has at least one CO Code (or prefix) set
aside for testing purposes.  If you are looking for test numbers, these
are the prefixes to scan, but be warned - you may not be able to access
these prefixes outside their home area codes.  If one prefix does not
seem to be working, try another for your area code - some plant test
codes are regional while others are area-code-wide.

If none of the exchanges for your area seems to respond, try a few
numbers with 1 plus the area code then the number.  Just because you
have to dial "1" doesn't necessarily mean you will be charged for the
call.

As with other prefixes, don't scan from home - there may be backdoors
to 911, security and other numbers that you really don't want to be
calling from home.

Suggestions (Where NXX is the prefix you are scanning):

NXX-00XX       
NXX-11XX 
NXX-99XX        - These ranges commonly contain test and other 
                  interesting numbers in in-service CO Codes.
NXX-X111        - Used often in Telus areas
NXX-ANAC (2622)
NXX-4TEL (4835) - 4Tel is a legacy counterpart to the DATU
NXX-5632        - 5632 is a keypad diamond that appears frequently 
                  as a password, access code, etc.  
NXX-LMOS (5667) - same as NXX-LOOP
NXX-DATU (3288) 
NXX-RNCC (7622)
NXX-TEST (8378) - particularly in temporary test CO codes for 
                  newly-split NPAs
