| First 6 Digits | IIN (Issuer Identification Number) |
| Next 9 Digits | Account Number |
| Last Digit | Check Digit |
The Basics of Credit Card Numbers
The 16-digit number on your credit card is divided into three main parts: the Issuer Identification Number (IIN), the account number, and the check digit.
a) What is an IIN?
The IIN, also known as the Bank Identification Number (BIN), comprises the first six digits of your credit card number.
This segment identifies the major card network (Visa, Mastercard, American Express, Rupay etc.).
b) Account Details:
The next nine digits make up your unique account number. This part of the number is specific to you and your account, ensuring that your transactions are correctly attributed to you.
c) The Check Digit (Last Digit)
This special number is calculated using a fancy algorithm to ensure the entire card number is valid.
Beyond the 16 Digits
There are other crucial numbers to remember for secure transactions:
| Crucial Number | Details |
|---|---|
| CVV | Card Verification Value |
| Expiry Date | Reminder to get a new card |
CVV (Card Verification Value): This 3- or 4-digit code, usually found on the back of your card, adds an extra layer of security for online and phone purchases. It verifies that you have the physical card and not just the number.
Expiry Date: This tells you the month and year your card expires. After that date, you’ll need a new card to continue using it. They play a crucial role in security.
Keeping Your Credit Card Safe
- Memorize: Try to memorize your card number and CVV instead of writing them down.
- Beware: Never share your full card details or CVV with anyone online or over the phone unless you absolutely trust the source.
- Monitor: Regularly check your credit card statements for any suspicious activity.
- For added security, consider enabling two-factor authentication for online transactions.
By understanding and keeping your credit card numbers secure, you can enjoy the convenience and benefits of plastic with peace of mind and shop online with confidence.
