> may be criminal fraud I can't say it isn't, but I also can't think of a specific reason that it is. Payment processing uses address information for two main purposes: (1) determining sales tax jurisdiction/amount and (2) as an authentication factor (along with card number, CVV, and name). In any normal purchase, giving a fake address could cause you to pay the wrong amount of taxes and/or taxes to the wrong people, which would be a legal issue. But this is a charitable donation, so that doesn't apply here. The authentication thing is probably OK, too, since you are an authorized user of the card. You are giving wrong information, but not in order to gain access to something you're not supposed to have access to. Maybe there's some other reason, though. Also, giving a fake address might violate some kind of agreement with the card company, although I kind of doubt they care if it doesn't cause them a practical problem.
