A Credit Card Validation Code (CCV Code) is a set of numbers on a credit card that are used to help verify that the card is legitimate.
The numbers are found on the back of the card near the signature box. They are the last three numbers listed, and are used to help keep credit card fraud down during online or mail order purchases.
The Credit Card Validation Code usually needs to be listed along with the credit card number to further verify that the card is working and that a theft is not being committed during these transactions.
