The CVC (Card Verification Code), also known as CVC2/CVV2, is a security feature for credit or debit card transactions. This ensures increased protection against credit card fraud.
VISA/MasterCard
The CVC code is printed on your card in the signature area at the back of the card. It is the 3 last digits after the credit card number in the signature area of the card.

American Express
You can find your four-digit card verification number on the front of your American Express credit card – above the credit card number on either the right or the left side of your credit card.
