What Is Debit Card Number? How To Find a Debit Card Number?

With the growth of technology in the banking sector, you no longer need to rely on cash transactions. Today, a Debit Card allows you to access funds in your bank account. You can also purchase products and services, pay bills, and settle other payments quickly with Debit Cards. Plus, you can use your Debit Card to withdraw cash from ATMs as needed. While using your Debit Card, you may have noticed a 16-digit number printed on it. Read on to understand what a Debit Card number signifies.

A Debit Card number is a set of unique digits serving as identifiers of your Debit Card. The number is essential as it is used to ensure that the transactions carried out through your Debit Card are legitimate. When you use your Debit Card, the connecting server, whether the recipient’s network or the ATM, reads the card number on the Debit Card to connect with your bank. It acts as a code that helps your money move safely from your account. 

The 16-digit bank card number on a Debit Card reflects your linked bank account. It is also important from a security point of view. Each digit serves a specific purpose. The first six digits represent the Bank Identification Number; the remaining ten are known as the Unique Account Number. Here’s a detailed breakdown of the structure of a typical card number on an ATM Card: 

The First Digit
The first digit of a Debit Card is known as the Major Industry Identifier (MII). It is used to identify the network that issues the MII code, which could be banking and finance, petroleum, airlines, telecommunication, and other industries.

The First 6 Digits
The first six digits are collectively known as the Issuer Identification Number (IIN). They are used to highlight the card-issuing bank. The company’s IIN for a MasterCard-enabled Debit Card will be – 5XXXXX, and for a Visa-enabled Debit Card, it is 4XXXXX.

The Next 9 Numbers (7th to the 15th Digit)
The numbers displayed on the Debit Card from the 7th to the 15th digit are linked to your bank account number. They are not the same as your account number but are linked to your bank account. The card provider issues these numbers to identify your account.

The Last Digit
The last digit on your Debit Card is the check digit. It indicates the validity of your Debit Card. The sole purpose of this digit is to validate the remaining digits displayed on your Debit Card.

The 16 digits displayed on a Debit Card are unique to each card and are a means to identify the account holder, bank account, and the card issuing company. If you suspect someone accessing your Debit Card number without your authorisation, you can contact your bank and have the card blocked immediately. You can then apply for a duplicate Debit Card.
