Keybank National Association Credit Card IIN List

Keybank National Association issues credit and debit cards in United States under a total of two different Issuer Identification Numbers, or IINs (also called bank identification numbers, or BINs). For banks with multiple IINs, cards of the same type or within the same region will generally be issued under the same IIN. The IIN makes up the first six digits of all credit or debit cards issued by Keybank National Association, followed by the primary account number (PAN) and a check digit.
