Where is the 4-digit Card Identifier Code located on an American Express card?

• A. On the back near the magnetic stripe.
• B. On the front, near the account number.
• C. On the front near the cardholder's photo.
• D. On the front, near the expiration date.

Answer: (B)

American Express uses a four-digit security code called CID that is printed on the front of the card, near the account number. This placement helps distinguish AmEx from other networks, which place their three-digit CVV on the back of the card. So the correct location is on the front, near the account number. The other options describe locations that aren’t how AmEx shows its security code.
