Also Known As
The Visa card issue number is also known as the verification code (V-code), card security code (CSC), card verification value (CVV, CV2) and card code verification (CCV).
The Visa card issue number can be found on the back of the card either on the signature strip after the 16-digit credit card number, or on the signature strip after a four-digit number.
The Visa card issue number is used to verify that the credit card number has not been stolen. It is used to verify that the card is present when making purchases in situations where the card cannot be swiped, such as online purchases or phone orders. It helps protect against some types of credit card fraud. The Visa card number, however, does not protect against those who have had their credit cards stolen (it only protects against stolen credit card numbers).
Most criminals that have your information will be able to present the credit card number but not the Visa card issue number. Some criminals have set up phishing scams that will only ask you for your Visa card issue number. Remember not to give your Visa identification number to anyone except for a trusted merchant.
Several nations outside of the United States have made it a law that the card issue number must be provided when making any purchase where the card is not present.
