On occasion, I try to make a purchase in the US or from a US online vendor and they simply will not sell without a US SS number. I tell them I am Cdn and so don't have one, in which case the vendor sometimes relents, but not always. So what is the best way for me to get around this requirement? Would it work if I simply made up a number? Before posting, please remember that it is against forum rules to explain how to do things illegally.
