How do I change the name on my credit card? Me and my dad have the same first name (I'm not a Jr though) and it's causing a lot of confusion. Like someone from the bank called and they were like "Is X here?" and I thought they was asking for my dad and I said "No" and turns out it was for me. I just want to use my middle name. Is that possible though or do I need to legally change my name for that?
