What is the Credit Card Security Code?
It is an important new Internet security feature that now appears on the back of most Visa and MasterCards (including debit cards), and on the front of most types of American Express cards. This new code is a three or four-digit number which provides a cryptographic check of the information embossed on the card.

The security code helps validate that the customer placing the online order actually has the credit card in his/her possession, and that the credit/debit card account is legitimate.

Where is Security Code Located?
The Visa/MasterCard three-digit value is printed on the signature panel on the back of card immediately following the card's account number.

For American Express, the 4-digit security code is found on the front of the card just above and to the right of the credit card number.

The security code is only printed the card and it is not contained in the magnetic stripe information nor does it appear on sales receipts or billing statements - you must have the card in your possession in order to use this code.

Do I Have to Enter This Security Code?
If this code is printed on your card, YES, you must enter the code. Visa, MasterCard, and American Express now require Internet stores to obtain the security code for all cards that have a code printed on them. In order for this transaction to be accepted and processed, you must enter this code if it's printed on your card. This is done for your protection.
