Where Is the Credit Card Security Code Written?
The CVV, or card verification value, is a three- or four-digit number. The network payment processor determines the CVV’s location.
Visa, Mastercard, and Discover all have a three-digit CVV on the back of the card that you must enter when making a purchase.
There is a four-digit CVV on the front of the card. American Express issues this CVV.
Since knowing the CVV code number requires holding the card, the CVV is intended to strengthen security. For example, if your credit card number is stolen and someone tries to make an online purchase using it, they will be unable to do so unless they know your CVV.
When you order a pizza over the phone, you can also use this code. Your credit card number is given, and the restaurant employee requests the card’s expiration date and its CVV (Card Verification Value). If you’re looking at the real credit card, the answer is obvious.
