Webster Bank Credit Card IIN List
Webster Bank 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 Webster Bank, followed by the primary account number (PAN) and a check digit.
