About American Express
American Express (often shown as “AMERICAN EXPRESS,” “AMEX,” or “AMEX *[Merchant/Service]*” on your statement) is a global financial services company based in New York, NY. It issues credit and charge cards to consumers and businesses, provides rewards programs, travel booking, airport lounge access, and foreign exchange services, and also acts as a payment processor for millions of merchants worldwide. Popular U.S. cards include Blue Cash Everyday (no annual fee), American Express® Gold Card (annual fee), and The Platinum Card® from American Express (higher annual fee with premium travel benefits).
A charge from American Express may appear on your bank or card statement for several reasons. If you’re an American Express cardmember, it could be your regular monthly payment, an automatic payment (autopay) you set up, an annual or monthly card fee, a balance transfer, or interest/late fees. You may also see American Express if they processed a payment for another merchant (for example, online retailers, travel bookings, or subscriptions that bill via Amex), or as a temporary authorization hold for things like hotel stays, car rentals, gas stations, or online purchases to verify your card. Some free trials or introductory offers convert into paid subscriptions that then bill through American Express.
To verify or resolve questions about an American Express charge, start by logging into your account at americanexpress.com or in the Amex mobile app and reviewing your recent transactions in detail (tap or click a transaction to see the full merchant name, date, and any related notes). Compare the amount and date with your emails, receipts, hotel or travel confirmations, and any apps or subscriptions linked to your Amex card. If you still don’t recognize the charge, call the number on the back of your card or use secure chat in the app; American Express can clarify the merchant, explain authorizations vs. posted charges, help with refunds or billing disputes, cancel stored card details, and, if needed, close and reissue your card in cases of suspected fraud.
