What is a BIN?
A Bank Identification Number (BIN) is the first 6 to 11 digits of a credit or debit card number. Also known as an Issuer Identification Number (IIN), it uniquely identifies the financial institution that issued the card.
BINs are essential for payment processing and fraud prevention. When a transaction is initiated, the BIN is used to route the payment to the correct card network and issuing bank for authorization.
By checking a BIN, merchants and payment processors can determine:
- The issuing bank or financial institution
- The card brand (Visa, Mastercard, American Express, etc.)
- The card type (debit, credit, or prepaid)
- The card level (Classic, Gold, Platinum, Business, etc.)
- The country where the card was issued
