How to find your credit card security code:
On a Visa, MasterCard or Discover card, please turn your card over and look in the signature strip. You will find either the entire 16-digit string of your card number, or just the last 4 digits, followed by a space, followed by a 3-digit number. That 3-digit number is your security code. (See below)
On American Express Cards, the security code is a 4-digit number that appears above the end of your card number. (See below)
What is a Card Security Code?
The card security code is a security measure we require for all transactions. Since a card security code is listed on your credit card, but is not stored anywhere, the only way to know the correct security code for your credit card is to have the authentic card. All VISA, MasterCard, Discover and American Express cards made in America in the past 5 years have a card security code, while those in Europe and Asia will be joining the program shortly *** (please see bottom).
Visa & Mastercard:
This number is printed on your MasterCard & Visa cards in the signature area of the back of the card. It is the last 3 digits AFTER the credit card number in the signature area of the card. If you cannot read your card security code, you will have to contact the issuing bank.
American Express cards show the card security code printed above and to the right of the imprinted card number on the front of the card.
A three digit non-embossed number is printed on the back of the Discover card after the account number within the signature box. If you cannot read your card security code, you will have to contact the issuing bank.
***If your European or Asian credit card does not have a card security code, you may enter 000.
