CVV/CVV2/CCV

Called differently by different organizations, either CVV or CCV, its easiest to remember it by “Card Code Verification.” CVV is a three digit security code that is printed on the back of most credit cards (or 4 digits on the front of AmEx cards). The CVV verification is designed to reduce fraud in the card not present environment by validating that the customer making the transaction has the credit card in their possession. An internet merchant should almost always set their gateway to require a correct CVV match before approving a transaction to reduce fraud.
