IIN stands for Issuer Identification Number. It is a unique numeric code that identifies the financial institution or entity that issued a given payment card, including credit, debit, or prepaid cards.
The IIN acts as the initial set of digits found on the card, typically ranging from six to eight digits in length. These numbers are significant as they enable the routing of payment transactions effectively. The IIN helps identify the type of card, the brand or network associated with it, and the country of issuance.
Financial regulatory agencies, such as the International Organization for Standardization (ISO) and the American National Standards Institute (ANSI), define the structure and format of IINs. The IIN range assigned to each payment card issuer is unique, ensuring no duplication within the same network.
Merchants and payment processors utilize the IIN during the authorization process to determine the card issuer and validate the card's legitimacy. Additionally, it aids in recognizing various card types, such as credit, debit, or prepaid cards, allowing merchants to assess associated transaction fees accurately.
The IIN plays a crucial role in facilitating secure and efficient payment processing by establishing the connection between the payment card, the issuer, and the payment network.
