American Express Credit Card Dispute Process: Step by Step

Quick Answer: American Express asks you to contact the merchant first. If that fails, log in, open your transactions, select the charge and click "Dispute this Charge", then follow the prompts. Amex says most cases are resolved in under two weeks and complex ones can take up to 90 days. To keep your federal billing-error rights, send written notice within 60 days of the statement that first showed the charge.

The American Express credit card dispute process starts online: select the transaction, click "Dispute this Charge" and answer the prompts. Amex tracks every case on a disputes overview page where you upload documents, edit drafts or close the case. Most cases finish within two weeks, complex ones within 90 days, and the Fair Credit Billing Act gives you 60 days to put a billing error in writing.

Should you contact the merchant before disputing with Amex?

Yes, and Amex says so directly. Its help center answer on how to dispute a charge opens with "Before you open a dispute, please first contact the merchant directly." That is not just a formality. A merchant can usually issue a refund in days, while a dispute involves Amex asking the merchant for its side and waiting for an answer.

Keep the contact short and documented. Email or chat beats a phone call, because a written exchange becomes evidence if the merchant refuses. Note the date, the name of anyone you spoke with, and what they promised. If they promise a refund, give it a reasonable window and then check your activity for the credit before filing.

Two cases where you skip the merchant: a charge you do not recognize at all, and a charge you believe is fraud. Check first with anyone holding an additional card on your account. Amex's general education article on disputing a credit card charge points out that the primary card member is responsible for charges an additional card member made.

How do you dispute an Amex charge online?

The steps, from the Amex help center:

1. Log in to your American Express account and open your transactions.
2. Scroll to the charge and select it.
3. Click Dispute this Charge.
4. Follow the on-screen prompts. They ask what kind of problem it is and for the details Amex needs to start the case.

The help center hub also carries an "Open a dispute" link that goes to the inquiry and disputes area of your account. If you prefer a person, Amex says you can reach it through the chat icon in the bottom corner of the Home screen once you are logged in, or by calling the number on the back of your card.

Before you start, find the charge on your statement and note the exact date, amount and the merchant name as Amex printed it. A merchant name on a card statement often differs from the shop name on your receipt, and quoting the statement version avoids confusion about which charge you mean.

What happens after you file?

The disputes overview page is where the case lives. According to Amex's dispute status answer, you can check status there and also cancel ongoing disputes, upload documentation and edit dispute drafts. Drafts matter: if you start a dispute and stop to find a receipt, the case can wait as a draft instead of being lost.

On timing, Amex states that "most dispute cases are resolved in less than two weeks" and that complex cases may take up to 90 days, per its answer on how long a dispute takes.

On credits, the Blue Cash Everyday Card cardmember agreement (version dated June 30, 2026) says that if you dispute a charge with a merchant, Amex may credit the account for all or part of it. If Amex does, you assign your claims against the merchant for that amount to Amex and agree not to pursue the merchant for the credited sum. Read the agreement for your own card; the public help pages do not promise a temporary credit or say when one would appear.

While the case is open, keep paying. Amex's education article notes you may be able to withhold payment on the disputed amount but still have to make at least the minimum payment on time each month. A late payment during a dispute is a separate problem that the dispute will not fix.

If you sort the problem out with the merchant after filing, close the case yourself. Amex's answer on closing a dispute says to click "View Open Disputes" at the top of the disputes page and then "Close Dispute" next to the case.

Where do you send documents for an Amex dispute?

Amex lists three routes for additional documentation on an existing inquiry:

Put your account number and the inquiry reference number on every page you send. Amex asks for both so the documents land on the right case.

What to gather depends on the reason for the dispute:

• Charged twice or the wrong amount: the receipt or order confirmation showing the correct total, plus the statement lines showing both charges.
• Canceled subscription still billing: the cancellation confirmation email or screenshot and the date you canceled.
• Refund promised but not received: the merchant's written promise or return label and tracking.
• Item never arrived or arrived damaged: order details, delivery tracking, photos, and your messages to the merchant.
• A charge you don't recognize: confirmation that no additional card member made it.

If you are disputing several charges from one merchant over months, a spreadsheet of every matching transaction helps. Amex's own transaction history answer says the previous two years of transactions can be downloaded as PDF, Excel or CSV. For older activity you only have as statement PDFs, a converter such as QuickBankConvert turns them into rows you can filter by merchant; our guide to converting Amex statements to Excel or CSV walks through it.

The 60-day window under the Fair Credit Billing Act

The online dispute is Amex's process. Your legal protection comes from the Fair Credit Billing Act, and it has a written-notice requirement that a button click may not satisfy. The CFPB's answer on disputing a credit card charge says that to protect your rights you must send a written billing error notice within 60 calendar days after the charge appeared on your statement. The card company then has 30 days to confirm it received the notice, unless it has already resolved the dispute. If it decides you were right, the charge must come off your bill; if it decides the bill is correct, it must tell you why in writing, along with how much you owe and when.

For a billing error that matters to you, do both: open the dispute online for speed, and mail a short letter to the billing-inquiry address your statement gives, for the legal record. Keep copies and a log of follow-up calls, as the CFPB advises.

A dispute over the quality of goods or services follows a different route. The Amex education article lists extra conditions there: the purchase generally must have been made within 100 miles of your billing address, exceed $50 unless your issuer says otherwise, and follow a good-faith attempt to resolve it with the seller. If your purchase falls outside those limits, still ask: the agreement for your card, not the article, decides what Amex will do.

Fraud is a different track

If the charge is fraud rather than a disagreement with a merchant, you also need to stop more charges. Amex's freeze feature is not a full stop: its freeze answer says recurring bills still post, digital wallet transactions and some card-on-file online purchases can still go through, and the card unfreezes automatically after 7 days. For confirmed fraud, report it through chat or the number on the back of the card so Amex can act on the account itself. Then review the last few statements for smaller test charges from the same source; the Amex bank page covers getting those statements into a spreadsheet.
