Which term is Card Identification Number used on payment cards?

• A. CID
• B. CAV2
• C. CVC2
• D. CVV2

Answer: (A)

The term Card Identification Number is the label American Express uses for its security code on the card. It’s a four-digit number printed on the front of AmEx cards, near the card number. This distinguishes it from the other networks’ codes, such as CVV2 (Visa) and CVC2 (MasterCard), which are typically three digits on the back, and from other network-specific names like CAV2. So CID is the correct term because it’s the official name AmEx uses for that front, four-digit code. In practice, this value helps verify the cardholder during transactions where the card isn’t presented, and it isn’t stored after authorization per PCI DSS rules.
