I know visa is 4.. MC is 5.. etc etc.. But is there a 1 and 2? Thanks
      Answer1:I work for a large credit card company therefore process balance transfers all day long. I have never run across a credit card that begins with a 2 or a 1. Right, there is the 4 = Visa, 5 = Mastercard, 3 = american express, then there are ones that begin with 6... never a 1 or 2...unless it is some crazy department store or something. Hope that helps!
