CC numbers are something that you definitely do not own. You do not own your credit cards. They are the property of the corporations who issued them to you. That's why they can cancel/alter/confiscate them without going through the courts.

Same too for credit ratings. The right to view and alter them comes from various other common law rule (ie slander) but the credit rating itself belongs to the corporation that generates it.

A better analogy is - what is your credit score?
