Common questions
What can an investigator learn from a card's BIN/IIN alone?+
It reveals the issuing bank and payment network, letting investigators identify the financial institution to approach for account-level records tied to the full card number.
Is the BIN/IIN enough on its own to identify the cardholder?+
No, it only identifies the issuer, not the individual account or cardholder, so it must be paired with the remaining digits and issuer records to trace a specific transaction to a person.
