Why You Should Protect Your Security Code

Every credit card has a card security code printed on it. It may be called a CSC, a card verification value (CVV or CV2), card verification code (CVC) or card code verification (CCV), but you need to know what -- and more importantly, where -- it is.

Virtual terminals and payment gateways do not store the CVV2 code; therefore, employees and customer service representatives with access to these web-based payment interfaces, who otherwise have access to complete card numbers, expiration dates, and other information, still lack the CVV2 code.

This applies globally to anyone who stores, processes or transmits card holder data. However, some merchants in North America, such as Sears and Staples , require the code. For American Express cards, this has been an invariable practice for "card not present" transactions in European Union EU countries like Ireland and the United Kingdom since the start of To do this, a merchant or its employee would also have to note the CVV2 visually and record it, which is more likely to arouse the cardholder's suspicion.

Supplying the CSC code in a transaction is intended to verify that the customer has the card in their possession. Knowledge of the code proves that the customer has seen the card, or has seen a record made by somebody who saw the card.

The CSC for each card form 1 and 2 is generated by the card issuer when the card is issued. It is calculated by encrypting the bank card number and expiration date two fields printed on the card with encryption keys known only to the card issuer, and decimalising the result.
