I have 2 credit cards.

  He could request the billing address, I believe, and cross reference that. Of course you might have 2 billing addresses as well...

    ... or there might be two family members who live at the same address.

      They will have different names then? I mean if you think hard enough on these I'm sure theres ways these checks fail. I could see a billing address being a company or communal living at which there are two people with the same given name.

      You can also change your billing address easily with most credit cards - if nothing is being mailed to me (and I'm determined to get past this check), what makes me enter a real address I have access to for it? As for names, it's somewhat common - two of my credit cards are firstinitial lastname (as opposed to firstname lastname), and I happen to share firstinitial with my father. I've got a friend who was named after his father (firstname lastname III), but who doesn't use the generation suffix for anything aside from his passport.

  But are you willing to give them both to some small internet site? I'm sure that there are a few edge cases like this who are comfortable doing that but I'd likely assume 90+% would not.
