If I can't find my Card after I temporarily block it, how do I report it lost or stolen?

If you think your Card has been lost or stolen, please call American Express and order a replacement Card, which will cancel your existing Card and a new Card will be sent to you. If you think fraudulent activity may have occurred on your Card, please contact us immediately.
