All credit cards have a unique security code to help prevent fraudulent purchases. Depending on the type of credit card, the security code might be three or four digits and found on the front or back of the credit card. So, where is the security code on an American Express® card, and when might it be used?
Where Is the Security Code on an American Express Card?
The American Express, Member FDIC, security code is the four-digit number located on the front of the card, just above and to the right of the card number. This security code is not the card’s PIN.
This security code is also referred to as a CVV or a CID. CVV stands for card verification value, and CID stands for card identification number.
When You Need Your American Express Security Code
When an American Express® Card Member swipes the physical card at a retailer, the card machine reads the card’s number and CVV code to process the transaction. In these cases, you do not need to provide the CVV in any other way. But when do you need it?
Activating a New Card
American Express® Card Members are usually asked for this code when activating a new card. This ensures that the card number has not been compromised before the physical card is received by the cardholder.
For online, phone or other card-not-present purchases, the Card Member must manually enter the CVV code along with the card number. This verifies that the person making the purchase is in possession of the physical card. Online retailers often use the terms CVV or CID rather than security code when requesting credit card information during checkout.
Anyone worried about retailer data breaches of customer credit card data should know that the Payment Card Industry Data Security Standard, which sets the minimum standard for data security, does not permit sites to store credit card CVV codes.
This means that while a data breach might expose credit card numbers, it should not expose the associated CVV codes.
“Where is the security code on an American Express?” is an important question to know the answer to, since that number is required for credit card purchases.
More important, though, is knowing how to protect your American Express CVV code. Card Members should only shop from trusted online sites and avoid providing card information for any transaction they did not initiate.
