What is an IIN list? An IIN list, also known as an Issuer Identification Number list, is a critical component in the payment card industry. It serves as a directory of financial institutions that issue payment cards, such as credit cards and debit cards.
Each IIN is a unique six-digit number that identifies the institution that issued the card. The IIN is used by payment networks, such as Visa and Mastercard, to route transactions to the correct issuer. This allows the issuer to authorize and process the transaction.

IIN lists are also used by merchants to identify the type of card that is being used, which can help them to determine the appropriate fees and charges.
