RE:RE:RE:RE:RE:RE:RE:regardingI think the Social Security Number is to verify address and/or ID, name. I believe this is pretty standard for sportsbooks or at least some type of ID. I used to have to provide one with Bet365, William Hill, Ultimate Bet, Full Tilt, etc., back in my gambling days. It did ask me for a US address, I dont think it had to be in NJ.
