The CVV (Card Verification Value) Number on your debit or credit card is a 3 or 4 digit code, used for security purposes during purchases at Online Merchants. The number on VISA, MasterCard and Discover branded credit / debit cards is a 3 digit numeric code, and on American Express branded credit / debit card it is a 4 digit numeric code.
The CVV number can be located at the back of your credit or debit card , as illustrated in the image below:
Providing your CVV number to an online merchant proves that you actually have the physical credit or debit card, and helps to keep you secure while reducing the chances of fraud. CVV numbers are NOT your card’s secret PIN (Personal Identification Number).
You should never enter your PIN number when asked to provide your CVV. PIN numbers allow you to use your credit or debit card at an ATM or when making an in-person purchase with your debit card or a cash advance with any credit card, while the CVV number is used on purchasing items and goods at Online Merchants.
CVV numbers are also known as CVC (Card Verification Code) or CSC numbers (“Card Security Code”), as well as CVV2 or CVC2 numbers, which are the same as CVV numbers, except that they have been generated by a 2nd generation process that makes them harder to “guess”.
Need of CVV Number
Getting the card details of someone else is quite easy nowadays. For example CCTV cameras are in operation in almost every shop and follow you while paying. Not only because of this fact the CVV / CVC verification code is located on the back of your payment card and represents the basic security feature. Therefore CVV/CVC code is required for all online payments where the card is not present and the PIN code cannot be entered.
