What is an IIN?

In IIN, or "Issuer Identification Number", is generally the first 1-6 digits of a credit card number. Rather than being linked to the account number of the credit card holder, these digits identify the bank which issued the credit card.

IINs are extremely valuable to developers for combating fraud, as they can also reveal information such as country of issue, card schema, and card type (debit or credit).

CreditCardValidator has a complete database of credit card IINs that are free to browse.

Disclaimer: Thank you for using! Please note that while we strive to ensure that our list of credit/debit card IIN/BINs and other payment card data is complete and up to date, we have to provide this resource on an AS-IS basis and cannot guarantee its accuracy.

None of the data you enter on this site will be stored or cached on our servers. All of our credit card verification tools are client-side, so entered data never leaves your browser.
