Online Help: Credit Card Verification Number
Card Code (CVV2 - CVC2 - CID) is a three or four-digit security code that is printed on credit cards. The value appears in reverse italic at the top of the signature panel on the back of the card (Visa, MasterCard, and Discover), or on the front of the card just above the end of the credit card number (American Express).
These additional numbers provide an extra measure of security against unauthorized credit card transactions. The credit card would need to be present for the purchaser to know the Card Code number, as it is not stored on any system outside of the credit card issuer.
We use Card Code verification to further protect you and your private information. Please see card examples below:
