[TIN] Amazon Affilate.

So, I've made my amazon affilate account and I wanted to ask if amazon checks the TIN if it's a real one since in the last weak I've purchased a TIN service for italy since they have 0% tax over there, and if it works i can use it to save $$'s ..
Would like to hear from people who knows about this area before i'm fuxking myself over there.
