Your credit card CVV number is also called a Card Security Code (CSC) or a Card Verification Code (CVC). Thus, every time you swipe your credit card, the data on the magnetic strip is used to verify your identity, and your CVV confirms the same, making your transaction secure. This CVV number is a decimal representation of a code specifically assigned to your data and known only to your card issuer. While the magnetic strip contains your data, a unique 3 or 4-digit code is assigned to the back of your card. Cardholders must protect their CVV and not share it with anyone to avoid falling prey to cyber fraud.ĬVV stands for Card Verification Value and refers to the magnetic strip behind your card. The CVV code, which is distinct from the card’s PIN, is required while making online transactions. Also known as card security code or card verification code, it acts as an additional security layer protecting your data during online transactions or card swipes at POS machines. A card verification value or a CVV number is a 3-digit code printed at the back of a credit or debit card.
