If this code is printed on your card, then YES, you must enter the code. Visa, MasterCard, and Discover are now starting to require Internet stores to obtain the security code for all cards that have a code printed on them.

Most internet mail order companies are asking for this number or will be in the near future. This number is an added measure of security for merchant and customers alike. Since we don't get the opportunity to meet our customers face to face, or to ask for a signature, or ID, this is the one security feature we use to make sure the credit card is in the hand of the person who orders. Some banks that issue credit cards require this number to be given on all internet or mail order transaction. See similar questions...

CVV code stands for Card Verification Value Code. The CVV code is a security feature for "card not present" transactions (e.g., Internet transactions), and now appears on most (but not all) major credit and debit cards. This new feature is a three- or four-digit code which provides a cryptographic check of the information embossed on the card. Therefore, the CVV code is not part of the card number itself.
