The Card Security Code (CSC) is a 3- or 4-digit number printed on your credit card. It provides added security when you use your card on the Internet or over the phone. The number appears only on the card itself, not on receipts or statements.
We ask for the CSC when you enter your payment information. This helps ensure that anyone placing an order with FTD.com has the card in his or her possession and is not using a stolen credit card number.
