Bank Card Number - Other Codes

Other Codes

The Card Security Code is typically the last three digits printed on the signature strip on the back of the card. On American Express cards, the Card Security Code is a printed (not embossed) group of four digits on the front towards the right.

The Card Security Code (CSC), sometimes called Card Verification Value (CVV or CV2), Card Verification Value Code (CVVC), Card Verification Code (CVC), Verification Code (V-Code or V Code), or Card Code Verification (CCV) is a security feature for credit or debit card transactions, giving increased protection against credit card fraud.

There are actually several types of security codes:

• The first code, called CVC1 or CVV1, is encoded on the magnetic stripe of the card and used for transactions in person.
• The second code, and the most cited, is CVV2 or CVC2. This CSC (also known as a CCID or Credit Card ID) is often asked for by merchants for them to secure "card not present" transactions occurring over the Internet, by mail, fax or over the phone. In many countries in Western Europe, due to increased attempts at card fraud, it is now mandatory to provide this code when the cardholder is not present.
• Contactless card and chip cards may supply their own codes generated electronically, such as iCVV or Dynamic CVV.
