Card Verification Number Scheme ("CVS Code")

CheckUp Software takes credit card security seriously. During the processing of your credit card purchase, we ask for an additional piece of information known as the "CVS Code" (Card Verification Number Scheme). The CVS Code is a sequence of numbers printed somewhere on the card. Most all credit cards carry this code; however, the location of the code varies.

The following visual guide should help you in locating your credit card's CVS Code:

Visa - MasterCard -  Discover

On Visa, MasterCard and Discover cards, the CVS Code is a 3 digit number located on the back of the card such as shown below:

American Express

On American Express cards, the CVS Code is a 4 digit number located on the front of the card such as shown below:
