To report a lost American Express credit card, immediately call American Express customer service at 1 (800)-528-4800. American Express will cancel the lost card and send a replacement credit card after verifying your identity over the phone. American Express allows you to report a lost credit card through its website or mobile app.
How to Report a Lost American Express Credit Card
- Call American Express customer service at 1 (800)-528-4800.
- Inform the customer service representative that you’ve lost your credit card.
- Verify your identity by providing any requested information, such as your date of birth or the last four digits of your Social Security number.
- Ask the American Express rep to cancel your old credit card and send a replacement.
Replacement cards from American Express will generally arrive within 1-5 business days. You may be able to get expedited delivery when you call to report the lost card, but make sure to ask whether there will be a fee. Once you receive the replacement card, you will need to activate it before making any purchases.
Finally, you won’t be held liable for fraudulent charges made by anyone who may have found or stolen your American Express card. This is because all American Express credit cards have a $0 liability guarantee. That said, you should still report any unauthorized charges as soon as you notice them on your billing statement.
