I am guessing here that the OP is attempting to crack somebody's email account, they discovered that the answer to the secret question was some Canadian postal code known to the account owner, which is described in the secret question prompt as "the Canadian zip code", and the wannabee cracker thinks that there is only one Canadian "zip code" (!)
kasrawis, there are about 33 million people in Canada, and I kind of think that the Canadian Post Office needs more than one code to get all the mail delivered...
