How American Express handles disputed charges
When you spot a charge on your American Express bill that you don't recognize or believe is wrong, you can file a dispute directly with American Express. The company calls this process a chargeback or dispute claim. American Express investigates your claim, contacts the merchant, and either removes the charge, credits your account, or asks you for more information to move forward.
The timeline matters: you have up to 120 days from the transaction date to report a dispute to American Express. After that window closes, the company cannot reopen the case. Most disputes are resolved within 30 to 60 days, though complex cases can take longer.
American Express handles disputes differently than Visa or Mastercard because American Express is both the card issuer and the payment network. This means fewer middlemen and often faster resolution, but it also means American Express has direct relationships with merchants and may push back harder if the merchant contests your claim.
Key Takeaways
- You have 120 days from the transaction date to report a dispute to American Express, either online through your account or by calling the number on the back of your card.
- American Express will ask you to describe what went wrong — whether the charge was unauthorized, the merchant didn't deliver, the item arrived damaged, or the amount was incorrect.
- The merchant gets a chance to respond to your dispute, and American Express reviews both sides before deciding whether to credit your account.
- If American Express rules against you, you can submit additional evidence or documentation to reopen the case, but the company's decision is final after the second review.
Starting a dispute through your American Express account
Log into your American Express online account or mobile app and find the transaction you want to dispute. Most accounts show a "Report a Problem" or "Dispute This Charge" link next to each transaction. Click it and select the reason that best matches your situation.
American Express will ask you to choose from categories like "I don't recognize this charge," "The merchant charged me twice," "The amount is incorrect," "The item never arrived," "The item arrived damaged or defective," or "The merchant cancelled but still charged me." Pick the one that fits — this category shapes how American Express investigates.
After you select a reason, you'll write a brief explanation of what happened. Be specific: include dates, what you ordered or expected to receive, and what the merchant told you when you tried to resolve it. If you already contacted the merchant and they refused to help, say that. American Express uses this information to decide whether the merchant is likely to dispute your claim.
Reporting a dispute by phone
Call the number on the back of your American Express card and ask to report a disputed charge. A representative will pull up the transaction, ask you to describe the problem, and file the dispute on the spot. This route works well if you're unsure which reason category fits your situation — the representative can help you choose.
Phone disputes take the same amount of time as online disputes. The only advantage to calling is that you get when ready confirmation and a reference number, and you can ask questions about what happens next. Write down the reference number and the name of the representative you spoke with.
What American Express does after you file
American Express sends the dispute to the merchant and gives them a window — usually 10 to 20 days — to respond. The merchant can accept your claim and refund you, or they can submit evidence that the charge was valid. Common merchant responses include proof of delivery, a signed receipt, or documentation that you received the service.
If the merchant doesn't respond within the important date, American Express often rules in your favor by default. If the merchant does respond, American Express reviews both your account of events and theirs, then makes a decision. You'll receive a letter or email explaining the outcome.
During this process, the disputed amount may be temporarily removed from your balance while the investigation is underway. This is not a final credit — it's a provisional one. If American Express rules against you, the charge goes back on your bill.
When American Express rules in your favor
If American Express decides the dispute is valid, the charge is permanently removed from your account and you receive a credit. This credit appears as a statement credit within one or two billing cycles. You don't have to do anything else — the case closes.
Some disputes result in partial credits if American Express finds that part of the charge was valid but part was not. For example, if you ordered two items and only one arrived, American Express might credit you for the missing item but leave the other charge in place.
When American Express rules against you
If American Express decides the merchant's evidence is stronger than yours, the charge stays on your bill and any provisional credit is removed. You'll receive written notice of this decision. American Express will explain which evidence convinced them — usually a delivery confirmation, a signed receipt, or proof that you received the service.
You can submit additional evidence and ask American Express to reopen the case, but this is your final note. Gather any new documentation — emails from the merchant, photos of the damaged item, proof that you returned something, or anything else that supports your version of events. Send this to American Express within 10 days of receiving the decision letter.
After the second review, American Express's decision is final. You cannot dispute the same charge a third time. If you believe American Express made a serious error, you can file a complaint with the Consumer Financial Protection Bureau, but this does not overturn the charge.
Disputes for unauthorized charges
If someone else used your card number without permission, report it as an unauthorized charge. American Express treats these differently than merchant disputes. You are not responsible for unauthorized charges under federal law, and American Express typically credits your account while they investigate.
American Express will ask you to confirm which charges were yours and which were not. They may also ask whether you lost the physical card, whether your card number was compromised online, or whether you gave someone permission to use it. Answer honestly — if you gave someone permission and later changed your mind, that's a merchant dispute, not an unauthorized charge.
After you report unauthorized charges, American Express will cancel your current card and send you a new one with a different number. Charges made after you report the fraud are your responsibility, so report it as soon as you notice something wrong.
Frequently Asked Questions
How long does it take to get my money back after I dispute a charge?
Most disputes are resolved within 30 to 60 days. American Express may credit your account provisionally within a few days while they investigate, but the final decision takes longer. Complex cases or disputes the merchant contests can stretch to 90 days.
Can I dispute a charge if I already got a refund from the merchant?
No. If the merchant refunded you, there's nothing to dispute. If the refund was supposed to happen but hasn't appeared in your account after two billing cycles, contact the merchant to ask for a tracking number or proof of the refund, then dispute if they cannot provide it.
What if the merchant says I signed for the charge or agreed to it?
If you genuinely authorized the charge but the merchant didn't deliver or delivered something broken, that's still a valid dispute — authorization doesn't mean the merchant gets to keep your money if they don't hold up their end. Explain what was supposed to happen and what actually happened instead.
Can I dispute a charge while I'm still trying to resolve it with the merchant?
Yes. You don't have to wait for the merchant to respond. Filing a dispute with American Express doesn't prevent you from also negotiating with the merchant. If the merchant refunds you while the dispute is open, let American Express know and they'll close the case.
What happens if I dispute a charge and lose, then the merchant goes out of business?
Once American Express rules against you, the case is closed. If the merchant later closes or files for bankruptcy, that doesn't reopen your dispute or change the outcome. This is why it's important to submit all available evidence during the initial dispute process.
