Okay, I did a little digging and can give you some additional info. FICO has come out with a secondary rating called the "FICO 8 Bankcard" score. This does not replace the main FICO score with a range of 300 to 850. The FICO 8 Bankcard score is a new rating used by some credit card issuers specifically designed to be used for determining credit card candidate worthiness and that scale runs from 250 to 900. Citi is the main company using this and only for credit card purposes, but it's starting to gain some traction with other banks.
