The 15 or 16-digit number on the front of your credit card is essential for transaction authentication when you make a purchase. This is so that you can identify the payment network, the cardholder, and other details using the structure of credit card numbers.
The sequence of digits incorporates a validation check, too. Your credit card serves as a strong means of identification in addition to being a convenient tool thanks to these and other security features.
How do I read my credit card number?
Credit card numbers with 16 digits are associated with credit cards that are linked to major payment networks such as Visa, Mastercard, and Discover. However, American Express credit cards have fifteen digits.
An industry identifier, or Major Industry Identifier (MII), is represented by the first digit. If the number falls between two and six, a financial or banking institution issued the card. This digit also reveals the card’s payment network. Cards starting with “4”, for instance, are a part of the Visa network. A few other MIIs include:
- 1: Airlines
- 2: Airlines and Financial
- 3: Travel and Entertainment (includes Amex)
- 4: Banking and Financial (includes Visa)
- 5: Banking and Financial (includes Mastercard)
- 6: Merchandising and Banking (includes Discover)
- 7: Petroleum
- 8: Healthcare and Communications
- 9: Government
You can determine the identity of the card issuer and the product the card is associated with by adding the industry identifier to the following five digits. These serve as the bank identification number (BIN) or issuer identification number (IIN) for the card. To uniquely identify the cardholder, the seventh through the fifteenth (or fourteenth for American Express) digits form a sequence. Finally, the last digit is known as a “check” digit. This verifies the authenticity of the card and is based on a mathematical formula.

Is my credit card account number the same as my card number?
Although your credit card account number is a part of your card number, it is distinct from your card number because it is shorter.
How does a credit card account number work?
Your account number is a string of up to twelve digits that serves as a unique means for you to be identified as the credit card account owner. It’s assigned by the financial institution issuing the card.
Starting from the seventh digit and ending with the second-to-last digit, that is the account number on the card. Therefore, you would look at the long number on the front of your card and cross out the first six and last digits to find your Discover account number.
Your account number remains the same even if your credit card number changes due to loss or theft. Additionally, even though both cards are linked to the same account, an additional cardholder issued by American Express will have a different card number than the primary cardholder.
What is a credit card security code?
The CVV, or Card Verification Value, is a common term used to refer to a credit card security code.
Having to provide a CVV when making purchases allows you to prove that you are the owner of the credit card. This additional security against fraud is required because, in contrast to in-person transactions, online shopping does not require you to present a legitimate ID or provide your card’s PIN.
A CVV can be a three or four-digit number. The three-digit CVV code for Discover, Mastercard, and Visa credit cards is located on the back of the card. The four-digit security code for American Express credit cards is on the front.
Different payment networks call the CVV different names. For Visa, it is known as “CVV2,” and for Mastercard, it is known as “CVC” or “CVC2.” American Express refers to it as “CID” or “CSC,” while Discover refers to it as “CVD” or “CID.” ”.
The unique thing about CVV is that stores aren’t permitted to keep them. For this reason, even in the event that hackers manage to obtain your credit card number through a data breach, they will be unable to use it for online or phone purchases.
Why do credit cards expire?
Having to enter your credit card’s expiration date provides an additional degree of security against fraud. Without the expiration date, thieves will not be able to use a stolen credit card number.
Regular use of credit cards also causes wear and tear, so getting a new card every few years guarantees that your current card is secure and functional.
