ComplianceSigns: CVV-2 Information

What is Card Verification Value / CVV2?

CVV2 is an important security feature for credit card transactions on the Internet and over the phone. "CVV" stands for "Card Verification Value" (Discover Card calls it the "Cardmember ID").

On most credit cards, including Visa, Mastercard and Discover:
CVVs are a three-digit number printed in the signature space on the back of the card.
The CVV2 number is always the last group of numbers in the signature space on the back of the card. It is not part of your regular credit card number.
On American Express cards:
The CVV is a four-digit number on the front of the card.
It is printed (flat), not embossed like the card number.
The CVV2 number enhances fraud protection and helps to validate two things:
  • The customer has the credit card in their possession.
  • The credit card number is legitimate
By helping to prevent credit card fraud, the CVV2 number keeps costs down for everyone.
