Full Answer

CVV numbers are also referred to as CVV2 numbers and Card Security Code or CSC numbers.

The CVV code shows that a customer placing an order is the legitimate holder of the card. Credit card companies each have a specific term for their designated code. For example, VISA calls the code a CVV2, while MasterCard calls the number a CVC2. American Express refers to the security number as a CID.

The panel on the back of MasterCard and Visa cards feature a 16-digit account number followed by the CVV or CVC coded number. Some card issuers feature the final four digits of the number on the account, and that number is followed by the code value.
