I have a particular American Express card that I've had for a long time. For reasons involving shady merchants, I've twice asked American Express to reissue the card with a new number.
However, the new number is predictable from the old number (it's generated from the original number using a very obvious algorithm.) The new expiration date is predictable based on when the request for a reissue was made. Only the four-digit CVV2 code (or whatever AmEx calls it) isn't obviously predictable, and even that is showing some patterns making me think it's not completely random.
Doesn't this defeat the whole purpose of getting a new credit card number?
