What is the Card Verification Value (CVV2)?
The Card Verification Value (CVV2) or Card Validation Code (CVC2) is located on the back of Visa and MasterCard credit cards and is typically a separate group of 3 digits to the right of the signature strip. The Card Verification Value (CVV2)—sometimes also called the Card Verification Number (CVN)—is a security feature for credit or debit card transactions, giving increased protection against credit card fraud. This code is often asked for by merchants for them to secure “card not present” transactions occurring over the Internet, by mail, fax or over the phone. See Wikipedia – Card Security Code for more information.
