What is a Bank Identification Number (BIN)?
A Bank Identification Number (BIN), also known as an Issuer Identification Number (IIN), is the first 6-8 digits of a credit/debit card number. These digits act as a unique identifier for:
- The card’s issuing institution (e.g., bank or financial organization)
- The card type (credit, debit, prepaid, etc.)
- The card network (Visa, Mastercard, American Express, etc.)
- The country where the card was issued
BIN Structure Example:
| Card Number | BIN | Account Number | Check Digit |
|---|---|---|---|
| 4822 92** **** ***# | 482292 | ** **** *** | # |
