Understanding Card Verification Code (CVC)
The CVC is a three- or four-digit number printed on your credit card or debit card. It acts as an extra layer of security to verify that you have the physical card when making a purchase. For Visa and MasterCard, you can find the CVC on the back of your card near the signature strip. American Express cards have a four-digit number printed on the front.
The main purpose of the CVC is to prevent unauthorised transactions when you shop online or over the phone. Merchants ask for this code to ensure that even if someone steals your card details, they cannot complete a transaction without seeing your physical card. This reduces your risk of fraud since the CVC is not stored in merchant databases and cannot be easily obtained through data breaches.
What is the Difference Between CVC, CVV, and CID?
CVV (Card Verification Value) is used by Visa and MasterCard interchangeably with CVC.
CVC (Card Verification Code) is often used by payment networks to describe the same security features as CVV.
CID (Card Identification Number) is a four-digit code used by American Express cards.

Importance of the CVC
The CVC plays a crucial role in securing your online transactions by verifying that only you can make purchases with your card. During online transactions, providing your valid CVC ensures that even if someone has stolen your card number or expiration date, they cannot complete a purchase without this code.
You must protect your CVC from unauthorised access by never sharing it or storing it insecurely online.
How Does the CVC Work?
When you make an online purchase, you need to enter your card number, expiration date, and CVC. Merchants verify this information against records held by card networks to confirm you are the rightful cardholder. he CVC you enter is matched with data stored securely by your issuing bank but not shared with merchants or stored in their databases.
Your CVC acts as part of the transaction authorisation process. This ensures that only legitimate transactions using your card are approved. It also ensures added protection against data breaches.
Examples of CVC
For Visa or MasterCard, your CVC is a three-digit code on the back near the signature panel. For American Express, your CVC is a four-digit code printed on the front.
When you purchase items online, you must enter your name, card details, and CVC to complete payment securely.
Tips for Protecting Your CVC
Never share your CVC with anyone who contacts you, even if they claim to be from your bank. Avoid saving your card details on websites unless you fully trust them. Check your bank statements regularly for unauthorised transactions.
If you suspect your card or CVC on card has been compromised, contact your bank immediately. Report lost or stolen cards promptly. Monitor your account for unusual activity.
Always ensure that you use secure websites for online transactions and avoid sharing sensitive information over unsecured networks.
Do You Need a Verification Code?
The CVC is essential for your online transactions because it provides an extra layer of security that protects both you and merchants from fraud. By requiring this code for card-not-present transactions, merchants can verify that you have physical access to your card. Without a valid CVC, most of your online purchases cannot be completed securely.
Conclusion
CVC is a vital component in ensuring secure credit and debit card transactions. It prevents payment fraud by verifying your card ownership during online or phone purchases while safeguarding your sensitive financial information. It plays a critical role in preventing unauthorised use during card-not-present scenarios.
