The Ultimate Guide to Card Test Numbers

What Are Card Test Numbers?

Card test numbers, also known as CVV2, CVC2, or CVV, are three or four-digit numbers found on credit and debit cards. These numbers serve as an additional layer of security for online transactions.

How to Find a Card Test Number

You can find the card test number on the back of your card. For Visa, MasterCard, and Discover cards, it's the three-digit number located on the right side. For American Express cards, it's the four-digit number located on the front, just above the card number.

Using Card Test Numbers for Verification

When making an online purchase, the card test number is used to verify that the cardholder has physical possession of the card. This helps prevent fraud by ensuring that the person making the purchase has the card in hand.
