Frequently Asked Questions
What is a Bank Identification Number (BIN)?
A BIN (also known as Issuer Identification Number or IIN) consists of the first 6 to 8 digits of a payment card number that identifies the issuing institution, card network, and card tier.
Is it safe to check a BIN online?
Yes. A BIN only consists of the first 6-8 digits, which are public bank identifiers. Never enter complete 16-digit card numbers, expiration dates, or CVV/CVC codes online.
How does the Luhn algorithm work?
The Luhn algorithm (also known as Mod 10) is a checksum formula used to validate identification numbers, doubling every second digit from right to left to prevent input typos.
