Common problemAmerican Express
Can't activate Amex card
Wrong card details during confirmation
To confirm a new card, Amex asks for the card number, the 4-digit security code on the front of the card and some personal details. A mismatch stops the activation.
How to fix it
Confirm the card online with the card number, the 4-digit code on the front and your personal details.
Follow the steps on the sticker on the front of the new card.
In the Amex app, hold the card near your phone to confirm it.
Or type the card number and 4-digit code into the app.
