What Is the CVV2 Code?
The CVV2 code protects consumers by ensuring that the credit card is present at the time of sale. It prevents the use of your credit card without the CVV2 number. This number is a 3 or 4 digit code printed on the back of your card.

How Can I Find My CVV2 Code?
Visa, MasterCard and Discover:
Visa, MasterCard and Discover credit/debit cards have the three-digit value printed on the signature panel on the back of the card immediately following the card account number. The back panel of most Visa/MasterCard cards contains the full 16-digit account number, followed by the CVV/CVC code. Some banks, though, only show the last four digits of the account number followed by the code.

American Express:
American Express credit/debit cards have a four-digit value printed on the front of the card near the upper right hand corner.
