OK, but if I only un-freeze one, will the card issuer check THAT bureau? Or is it an unknown which they will check, so one needs to un-freeze all three to be sure? Or does each issuer (Chase, Citi, Barclay, etc) has their own 'favorite' so if I know which bureau each prefers, I only need to un-freeze that one? If that is true, we should add that info to the wiki
