Opens in a new window. Protecting your code is important because if someone has your credit card number, the expiration date of the card and your security code, they can make online purchases because it will appear to online merchants that the authorized cardholder you is completing the transaction. 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.

In the signature box or just to the right of it, you will see a series of digits. However long the series, the final three digits are the security code. American Express cardholders can find their security code on the front of the card, either to the left or right of the embossed digit card number. These four digits are printed in black, not embossed. Even as the U. Each financial institution will have its own guidelines for how to handle illegible security codes, but it may require reissuing the card.
Since the security code is a safety feature, just like your PIN, you will want to protect it. Generally, as long as you have a secure connection, you can safely provide it during online transactions. The merchant is prohibited, for security purposes, from storing the code.
However, never provide your security code to anyone, whether you know the individual or not, and never include it in an email email is unsecured communication. Once someone else has your security code, card number and card expiration date, it will appear to an online merchant that someone else, not you, is actually in possession of the card. The PIN is not printed or embedded on the card but is manually entered by the cardholder during point-of-sale card present transactions.
American Express started to use the CSC in , in response to growing Internet transactions and card member complaints of spending interruptions when the security of a card has been brought into question.
In , a new e-commerce technology called Motioncode was introduced, designed to automatically refresh the CVV code to a new one every hour or so. The card security code is typically the last three or four digits printed, not embossed like the card number, on the signature strip on the back of the card. On American Express cards, the card security code is the four digits printed not embossed on the front towards the right.
The card security code is not encoded on the magnetic stripe but is printed flat. As a security measure, merchants who require the CVV2 for " card not present " payment card transactions are required by the card issuer not to store the CVV2 once the individual transaction is authorized. 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. From Wikipedia, the free encyclopedia.
American Express also sometimes refers to a "Unique Card Code".
Rewards cards tend to have higher interest rates than non-rewards cards, making them. It doesn’t matter what you call them – a card security code (CSC), card verification value (CVV or CV2), card verification code (CVC) or even a card code verification (CCV) – those three or four digits provide an additional measure of credit card security when you make purchases online, by mail or over the phone. A card security code (CSC; also called card verification data [CVD], card verification number, card verification value [CVV], card verification value code, card verification code [CVC], verification code [V-code or V code], or signature panel code [SPC]) is a security feature for "card not present" payment card transactions instituted to reduce the incidence of credit card fraud.
