Card Verification (CV) Number Codes
When you request a credit card authorization, you can include the customer’s card verification number, a three-digit number printed on the back of Visa and MasterCard credit cards near the cardholder’s signature. If the customer cannot provide the correct number, the transaction may be fraudulent. The following table describes each card verification result code.
