Answer 1

Best Answer

The Card Validation Code (CVC) or Card Verification Value 2 Code (CVV2) provides consumers

and merchants with added credit card transaction security. These codes requires physical

access to the credit card, thus reducing the risk of Internet credit card fraud.

The CVC / CVV2 code is the three-digit code located after the credit card number on the back

of the card near the signature strip of Visa, MasterCard, and Discover cards, and as a

four digit code on the front of all American Express cards (see example below).

Card Validation Code

The 3-digit, non-embossed number printed on the signature panel on the back of the card immediately following the credit card account number. This number is required as an additional security precaution.
