durberville knows that. The problem is that TransUnion (USA) is treating a Canadian SIN as if it were an USA SSN. I see that TransUnion also does business in Canada. Perhaps there is no overlap between valid SIN's and SSN's, or TransUnion has some other method of distinguishing them, and they can use them as an unambiguous record key?
