FAQ
What is a BIN?
The Bank Identification Number (also IIN) is the first 6–8 digits of a card number. It identifies the card network, the issuing bank, the card type (debit, credit, prepaid) and the issuing country.
Why check a BIN?
To see which bank and country issued a card, whether it is debit, credit or prepaid, and to route payments or spot a mismatch between the card country and the customer's IP country — a common fraud signal.
Is it safe to enter my card number here?
Enter only the first 6–8 digits — that is all the lookup needs. Never paste a full card number with expiry and CVV into any website.
Why is a BIN not found?
Public BIN databases are incomplete: new ranges, private-label cards and test ranges are often missing. The scheme and length checks still work offline.
