If you’ve ever made an online purchase, conducted phone transactions, or provided your card details for non-contact payments, you’ve likely come across the term “CVV.” However, you may have wondered about its meaning, how to locate the CVV, and why it is necessary to provide it. Rest assured, you’re not alone in seeking answers to these questions.
What is a CVV Number?
A CVV three or four digit number security code printed on credit and debit cards to verify that the person making an online transaction has physical possession of the card. This code goes by different names, such as card security code (CSC), card verification code (CVC or CVC2), or card identification number (CID). Regardless of the name used, the purpose remains the same: to provide an additional layer of security and prevent fraudulent transactions.
How are CVVs Assigned?
Credit card companies generate CVV numbers using complex algorithms. These codes are not related to the cardholder’s personal information or account number, making them difficult to predict or guess. Each card is assigned a unique CVV number during the card production process to enhance security and prevent unauthorized use.
How Do I Find My Credit Card CVV Number?
Locating your CVV number depends on the type of credit card you have.
Visa, Mastercard, and Discover
For Visa, Mastercard, and Discover cards, the CVV number is printed on the back of the card. Look for a three-digit number at the end of the signature panel. This code is often positioned to the right of the panel but may vary slightly based on the card issuer. It is usually separate from the card’s 16-digit account number.

American Express
American Express cards have a four-digit CVV number printed on the front. Look for the number above the cardholder’s account number, typically on the right side of the card. Unlike other card brands, American Express places the CVV number on the front for easier access during online transactions.

What is the Difference Between a CVV Number and PIN?
CVV numbers are used for online and card-not-present transactions, the PIN is typically used for in-person transactions and ATM withdrawals. The CVV number verifies the card’s legitimacy during online transactions, while the PIN is a confidential code known only to the cardholder for authentication purposes.
Importance of Keeping the CVV Number Secure
Safeguarding your CVV number is crucial for protecting your financial information. Here’s why:
- Prevents unauthorized access: Keeping your CVV number secure reduces the risk of unauthorized individuals gaining access to your credit card information and making fraudulent transactions.
- Protects against online fraud and identity theft: CVV numbers act as a safeguard against online fraudsters who may attempt to use stolen card details. By keeping the CVV number private, you add an extra layer of protection to your online transactions.
Tips for Safeguarding the CVV number
- Never share your CVV number with anyone, including over the phone or email.
- Be cautious when entering your CVV number online and ensure you’re on a secure website.
- Regularly monitor your credit card statements for any unauthorized transactions.
- If your card is lost or stolen, notify your card issuer immediately to prevent misuse.
