To aid in the prevention of fraudulent credit card use, we require the 3 or 4 digit verification code on the back of your credit card.
For Visa, MasterCard and Discover Cards: Turn the card over and look at the signature box. You will find either the entire 16-digit credit card number or just the last 4 digits, followed by the 3-digit CCV.
For American Express Cards: The CCV is always located above the account number on the face of the card, sometimes on the left side and sometimes on the right. Note: Some American Express cards have a 4-digit number below the account number. This is not the CCV.
