What is the CVV number?
The CVV, CVC, or CID number is a 3-digit number printed on the back of Visa, Mastercard, and Discover credit and debit cards and a 4-digit number printed on the front of American Express credit and debit cards.
Where is the CVV number located?
  • Visa, Mastercard, and Discover - The last three digits of the numbers in the signature window on the back of the card.
  • American Express - The four digits displayed above top right or top left of credit card number.
Why must I enter the CVV number?

The CVV security number ensures that the person entering the credit card information online or over the phone has posession of the credit card at the time of purchase.
How does the CVV number protect me?

Requiring the CVV number to be entered during online purchases prevents criminals from using your credit card information to make online purchases.
