What is the CVC Number? CARD VERIFICATION VALUE CODE (CVC) CVC is a new authentication procedure established by credit card companies to further efforts towards reducing fraud for internet transactions. It consists of requiring a card holder to enter the CVC number in at transaction time to verify that the card is on hand.The CVC code is a security feature for "card not present" transactions (e.g., Internet transactions), and now appears on most (but not all) major credit and debit cards. This new feature is a three- or four-digit code which provides a cryptographic check of the information embossed on the card. Therefore, the CVC code is not part of the card number itself. The CVC code helps ascertain that the customer placing the order actually possesses the credit/debit card and that the card account is legitimate. Each credit card company has its own name for the CVC code, but it functions the same for all major card types. (VISA refers to the code as CVC2, MasterCard calls it CVC2, and American Express calls it CID.) The back panel of most Visa/MasterCard cards contain the full 16-digit account number, followed by the CVC code. Some banks, though, only show the last four digits of the account number followed by the code. To aid in the prevention of fraudulent credit card use, we now require the 3 or 4 digit code on the back of your credit card. When you submit your credit card information your data is protected by Secure Socket Layer (SSL) technology certified by a digital certificate. Where is the CVC Number? 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).
