What is a CVV Or Security Number, and Where Can I Find It?

A CVV or security number is normally a 3-digit numeric code available on the back of your credit or debit card. On American Express cards, it is a 4-digit numeric code located on the front of the card. This code is often used for verification purposes to prevent fraud, especially with online purchases. Providing the CVV number implies that the person placing the order has physical possession of the card.
