Credit Card Glossary: Terms and Definitions
CVV is one of the credit card industry’s several acronyms for the credit card security code that helps verify the legitimacy of a credit card. Depending on the card, the security code can be a three-digit or four-digit number, printed on either on the back of the card or the front. CVV stands for “card verification value” code. Other card issuers call their security codes CVV2 (Visa), CVC2 (MasterCard) or CID (American Express).
