What do 16 digits on the debit card mean? 

A debit card which is also known as ATM card is issued by banks when you open an account with them. Debit cards are really useful as a lot of things can be done easily. Debit cards can be used to withdraw cash from ATMs, shop online, pay bills and much more. The debit card has eliminated the hassles of visiting the bank branch to withdraw cash as you can easily withdraw cash at ATMs. You can carry out various online banking transactions using your debit card.

These days almost all bank holders have a debit card and they use it for various transactions. But, not everyone has complete knowledge on these cards. They just believe that some numbers are written on the front and back of the card. Most people are not aware on what exactly these numbers mean and that bank account details can be accessed through them.

These numbers not only represent details of your bank, but are also very important from the security point of view of the card. These numbers help in preventing frauds that occur at the time of online transactions.

What is the meaning of a 16 digit number on your debit card?

On the front of each debit card, a 16 digit code is written. These digits are divided into 3 parts as follows:

a) The first 6 digits on the card represent the Bank Identification Number.

b) The next 9 digits are the Unique Account Number of the cardholder.

c) The last digit is a Check digit for validation of the card.

Even your debit card has a date and year of the expiry. This is printed on your card so that you remember that your card will not work after this date. The expiry date is asked while carrying out online transactions.

The first 6 numbers on your card including the first digits are known as Issuer Identification Number or Bank Identification Number (BIN). They tell us about the company which has issued the card. Every bank in India has a different sequence of IIN numbers.

3. Next 9 numbers (7 to 15)

The next 9 digits of a card number from 7 to 15 is linked to your bank account number. But, it does not reveal anything about your bank. It is a unique number issued by the card provider which identifies your account.

The number helps verify that all the digits of your card are accurately entered while carrying out any transactions.
