The V-Code or Verification code is
located on the back of your credit card
along the the signature line.
There might be a long list of numbers or short list.
In either case it's always a 3 digit number
at the end of the line.
This number is to protect you in the event that somebody
stole your credit card number but not your actual credit card.
Without this number, we can not accept your credit card for payment.
