What is CVV2?
CVV2 is an important security feature for credit card transactions on the Internet and over the phone. "CVV" stands for "Card Verification Value" (Discover Card calls it the "Cardmember ID").

All VISA, MasterCard and American Express cards made in America in the past 5 years or so have a CVV2 number.
How to find your CVV2 number:
On a Visa or MasterCard, please turn your card over and look in the signature strip. You will find (either the entire 16-digit string of your card number, OR just the last 4 digits), followed by a space, followed by a 3-digit number. That 3-digit number is your CVV2 number. (See below)
Visa, MasterCard & Discover:
This number is printed on your MasterCard & Visa cards in the signature area of the back of the card. (it is the last 3 digits AFTER the credit card number in the signature area of the card).
IF YOU CANNOT READ YOUR CVV2 NUMBER, YOU WILL HAVE TO CONTACT THE ISSUING CREDITOR.
On American Express Cards, the CVV2 number is a 4-digit number that appears above the end of your card number. (See below)
American Express cards show the CVV2 printed above and to the right of the imprinted card number on the front of the card. It is printed (flat), not embossed like the card number.
