What is a BIN/IIN?
The Bank Identification Number (BIN), also known as Issuer Identification Number (IIN), is the first 6-8 digits of a payment card number. It identifies the institution that issued the card and can reveal details about the card type, brand, and issuing bank.
Why Use BIN Lookup?
BIN lookup is commonly used for fraud prevention, payment processing optimization, and card validation. It helps merchants identify card types, detect potentially fraudulent transactions, and apply appropriate processing rules.
