|Locating your Credit Card CCV2/CVV2 Security Code:
Your card security code for your MasterCard, Visa or Discover card is a three-digit number on the back of your credit card, immediately following your main card number.
The card security code for your American Express card is a four-digit number located on the front of your credit card, to the right or left above your main credit card number.
Why do we ask for this?
We ask for this information for your security, as it verifies for us that a credit card is in the physical possession of the person attempting to use it.
