What is the card security code for my credit card?

A card security code is a unique security feature of VISA, MasterCard, Discover, and American Express credit cards. By including it with your order, you help protect your account from fraud and you give us one more way of being sure your order is legitimate.

Finding your credit card security code:

VISA, MC, Discover users
The Card security code is the 3-digit number located on the back of your card, usually at the top of the signature strip.

American Express users
Look for the 4-digit number printed on the front of your card.
Depending on which card you have, you'll find this number in small type above your credit card's main number on either the left or right side.
