The first six or eight digits of a card number (including the initial MII digit) are known as the issuer identification number (IIN). These identify the card issuing institution that issued the card to the card holder. The rest of the number is allocated by the card issuer. The card number's ''length'' is its number of digits. Many card issuers print the entire IIN and account number on their card.
