What is Issuer Identification Number (IIN)

Posted on Monday, November 4th, 2024 | By IndusInd Bank

Today, every part of daily life has a digital component to it. Banking is no exception. On a daily basis, you use your cards to withdraw money from the account, pay for shopping, and much more. Digital transactions have become the norm, with millions of rupees exchanged daily. In such a situation, the security of your financial information is more crucial than ever. However, all most people can do in the name of financial security is avoid giving out details like ATM PINs. But have you ever wondered what banks and financial institutions do? How can they identify the card issuer during a transaction?

There is an often-overlooked detail that plays a vital role in the safety and speed of your transactions. The secret lies in a small but powerful component known as IIN, full form of which is the Issuer Identification Number.

This article delves into what an IIN is, unravel its significance, and explains how it influences your everyday banking experience.

What is Issuer Identification Number (IIN)?

The Issuer Identification Number (IIN), also called the Bank Identification Number (BIN), is a six-digit code on your card that helps identify the issuing institution. It consists of six digits:

1. First digit: The Major Industry Identifier (MII), indicating the card’s category (e.g., banking or travel).
2. Next five digits: These identify the specific issuing bank or institution, ensuring transactions are routed to the right entity.

This system ensures fast and secure processing of your card payments by directing transaction requests accurately.

How Does the IIN Number Work?

• When you use your card to make a purchase, the IIN (Issuer Identification Number) plays a vital role behind the scenes. It is the first thing the payment system checks to ensure your transaction is processed.

• The IIN is the first point of reference for the payment system. Once you swipe or tap your card, the system:
• Checks the IIN to identify the card issuer.
• Routes the transaction to the right financial institution.

• This process takes seconds and ensures your payment is fast, seamless, and secure.

For example, if you swipe your IndusInd Bank debit card, the payment system will read the IIN to identify IndusInd Bank. It will then route the transaction through their systems to complete the process.

It is a small detail in the grand scheme of things, but without the IIN, your payment would not reach the right place!

Why Is the IIN Number Important?

It is an understatement to say that the IIN number is important. It is crucial for security and fraud prevention. Here are a few reasons why the IIN is vital:

• The IIN immediately identifies the card issuer. It ensures the correct processing of transactions.
• The IIN verifies transaction details with the issuing institution to detect unauthorised transactions.

The IIN follows a global standard. This means it is recognised on an international level, which makes cross-border transactions seamless. The purpose of IIN is to enable quick and secure transactions. This paired with the no minimum balance requirement of zero-balance savings accounts can be an amazing financial setup for you.
