Frequently Asked Questions

A BIN (or Issuer Identification Number - IIN) refers to the initial 6 or 8 digits of a credit, debit, or prepaid card. It uniquely identifies the card network and issuing bank.

E-commerce merchants use BIN checking to verify whether a customer's billing country matches the issuing country of their card, flagging suspicious transactions early.

A BIN lookup reveals the card brand (Visa/MasterCard), issuing bank name, card type (Credit/Debit), card level (Gold/Platinum), and the country where the card was issued.

No. BIN checking only reveals public banking metadata. It never accesses personal cardholder identities, bank account numbers, or account balances.

Historically, BINs were 6 digits long. ISO/IEC 7812 expanded the standard to 8-digit BINs in 2022 to accommodate the growing number of financial institutions globally.
