Fetch Card IIN Information using IIN API

Fetch customer card IIN information before payment initiation using the IIN API.

The Issuer Identification Number (IIN, also known as BIN) is the first 6 digits of a credit or debit card. Our IIN API provides all the details about a given IIN.

Using this API, you can get details about customers' cards even before the payment is initiated. This helps you to determine whether the payment should be allowed.

For example, if you do not want to accept credit card payments from customers, you can use this API to detect the customer's card type by checking the IIN. Based on the response, you can decide whether to allow the payment to proceed or not.

Card Tokenisation

Tokenisation is a process by which the card number gets replaced by another virtual 16-digit number called Token. This token (or tokenised card number) is used to process payments instead of the actual card number.

A token is a unique digital identifier in mobile and online transactions. The first 6 or 9 digits of token created is referred to as token_iin.

RBI Guidelines on Tokenisation

As per RBI guidelines, businesses or Payment Aggregators cannot save actual card numbers on their servers. They can only tokenise the card and use these tokens for subsequent payments.

Tokenised IIN

The first 9 digits of the token are referred to as tokenised IIN.

  • For Visa, Mastercard and RuPay tokenised cards, the IIN is the first 9 digits of the token. This is referred to as token_iin. For example, 411111111.
  • For other networks, the length of Token IIN might change to 6 or 8 digits.

Handy Tips

  • You will get the token_iin from your tokenisation solution provider as part of the token entity.
  • If you use Razorpay as your tokenisation solution provider, you will get the token_iin within the card object. Refer to the token.card.token_iin parameter.

Uses

You can use this API to:

  • Check if the IIN of the card number entered by a customer is valid.
  • Check if the IIN is eligible for different payment flows such as recurring and EMI.
  • Get information about the card network, card type and issuing bank.
  • Detect customer's card type.
  • Fetch the actual card IIN for a given token IIN. This is currently supported for Visa and MasterCard.
