Bank Identification Number (“BIN”) or Issuer identification number (“IIN”) is the first six digits of a bank card number or payment cards number and it is part of ISO/IEC 7812. It is commonly used in credit cards and debit cards, stored-value cards, gift cards and other similar cards.
BIN is beneficial to identify a card brand, issuing institution or bank, country of issuance, card type and category of cards. This information is very useful in commercial business for fraud prevention, especially in online store.
