They can list all they want, but the fact remains if I have not given them a birth date, or have not given them the CVV number on my credit card, or my pets mother's maiden name, all of which they don't ask for, they can't use any of that to verify who I am, as they don't have anything to verify it against.

If Hilton wants to collect that information, they should just ask for it and not pretend it's some verification for something they don't have.

To the OP, I would just make up something and send it to them, and see if they verify it and respond. There's something very wrong with their request.
