I just added my checking acct and driver license number. When sending money to an email address, I take it the other email address has to be registered to AP as well?

As an aside, I know some members create multiple accounts (more than there are family members/friends). The limited factor as I see it is the SSN. I know some members make up SSN to create more accounts. Is there any reason this will cause problems? I know the law requires AP to get our SSN, but since there's no credit pull, I don't see why Amazon will need to run it.
