What is a CVV and Where do I find it?
CVD or CVV is an anti-fraud security feature to help verify that you are in possession of your credit card. For Visa/Mastercard, Discover, and most cards, the three-digit CVV number is printed on the signature panel on the back of the card immediately after the card's account number. For American Express, the four-digit CVV number is printed on the front of the card above the card account number.
NOTE: Some of the newer cards refer to it as a Security Code
