The CVV (Card Verification Value) is a 3-digit number on Visa, Mastercard, and Discover cards (located on the back), and a 4-digit number on American Express cards (on the front).47 The expiry date is typically displayed as MM/YY or MM/YYYY.47 These details are used to verify card ownership during online transactions.7

It is important to note that real card numbers should never be used in sandbox environments.2
