What is the CVV2 code?

The CVV2 code is a 3- or 4-digit code printed on your credit card.
We request this code as a security measure for our customers.
Requiring this information helps to ensure that the credit card is
present at the time of purchase. If you cannot find this code, or it
is illegible, please contact your credit card issuer.
