What is the CVV/CVC code and where can I find it? Aline C. 10 May 2022 10:41 Updated The CVV code is located on the back of your VIABUY Prepaid Mastercard, next to the signature field. CVV is an acronym in English that means card verification code. This refers to a 3-digit security code. To prevent misuse when you shop online, this code will be required to complete the purchase process, along with your card number, expiration date, and cardholder's name. The CVV code is randomly generated for your card number, so that payment systems can identify and ensure that the card number belongs to the CVV number entered. Only when these two numbers match, the payment is accepted by the merchant. Related articles How do I unblock the CVV? Why can I not log in? Does the VIABUY Prepaid Mastercard support 3D Secure?
