From what I have read the SSN that he is using is not an SSN at all. It is a CT taxpayers ID number. That is issued if they don't have your SSN. In this case it is because Barry used a CT address to avoid NY taxes. Researching it as a SSN wont find anything, you will have to look into the CT tax payers records. It could be under either of his names, because he just started calling himself Barrack at that time.
