How to file a dispute with Discover
When you spot a charge on your Discover card that you didn't make or that was processed incorrectly, Discover has a formal process to investigate it. You start by calling the number on the back of your card or logging into your online account and reporting the transaction. Discover will then open a dispute case, assign it a reference number, and begin gathering information from both you and the merchant.
The investigation typically takes 30 to 90 days. During this time, Discover may temporarily credit the disputed amount to your account while they work through the details — though this is not may provide and depends on the type of dispute. Once Discover reaches a conclusion, they'll notify you in writing of the outcome and whether the charge will be removed, reinstated, or adjusted.

What counts as a valid dispute
Discover recognizes several categories of disputes. An unauthorized transaction is a charge you did not make and did not authorize anyone else to make. A billing error is a charge that was processed twice, charged for the wrong amount, or posted to your account on the wrong date. A merchandise dispute occurs when you ordered something but it never arrived, arrived damaged, or was significantly different from what was described.
A quality dispute is trickier: you received the item, but it was defective or not as promised. Discover will investigate these, but the outcome often depends on whether you have documentation from the merchant acknowledging the problem. If you straightforward changed your mind about a purchase or no longer want an item, that is generally not a valid dispute — you would need to contact the merchant directly about a return.
Documents and information you'll need
Before you call or file your dispute online, gather what you have. For an unauthorized charge, you'll need to describe what happened and confirm you did not make the purchase. For a billing error, have your statement ready showing the incorrect charge. For a merchandise dispute, collect any emails or messages from the merchant, photos of damaged items, tracking information showing non-delivery, or the original product description if the item arrived different from what was advertised.
Discover will also ask for your account number, the transaction date, the merchant name, and the amount. If you've already contacted the merchant and they refused to refund you or didn't respond, mention that when you file — it strengthens your case. Keep copies of everything you send to Discover and note the reference number they give you so you can follow up if needed.
The temporary credit and what happens next
Discover may place a temporary credit on your account within two business days of opening your dispute, though this depends on the type of claim and the strength of your initial report. This credit is not final — it's a courtesy while they investigate. If Discover later determines the charge was valid, they will remove the temporary credit and you'll owe the amount again.
During the investigation, Discover contacts the merchant and asks them to provide evidence that the transaction was authorized and legitimate. The merchant may send receipts, signed authorizations, delivery confirmations, or communications with you. You'll have the chance to respond to anything the merchant submits. Once Discover has reviewed all the evidence, they make a final decision and notify you in writing within the 30- to 90-day window.
What to do if your dispute is denied
If Discover rules against you, they will explain their reasoning in the written decision. This does not mean you have no other options. If you believe Discover made an error, you can request that they reconsider — include any new evidence you've found and explain why you think their decision was wrong. Send this request in writing to the address Discover provides in their decision letter.
You also have the right to file a complaint with the Consumer Financial Protection Bureau (CFPB) if you believe Discover did not handle your dispute fairly. The CFPB investigates complaints about credit card companies and can pressure them to reconsider. You can file a complaint at consumerfinance.gov or by calling 1-855-411-2372. Filing a complaint does not overturn Discover's decision, but it creates a record and may lead to further review.
Disputes for recurring charges and subscriptions
If you're disputing a recurring charge — a subscription, membership, or automatic payment you thought you'd canceled — tell Discover that when you file. These disputes sometimes move faster because the merchant often has a clear record of whether you authorized the recurring charge and whether you requested cancellation. Bring any emails or messages showing you asked the merchant to stop the charges.
If the merchant claims you never canceled but you have evidence you did, Discover will weigh that evidence. If you canceled through the merchant's website or app, take a screenshot showing the cancellation confirmation. If you called or emailed, keep that documentation. The stronger your proof of cancellation, the more likely Discover will rule in your favor.
How disputes affect your account and credit
Filing a dispute does not hurt your credit score. Discover reports disputes to credit bureaus as pending investigations, not as missed payments or defaults. Once the dispute is resolved, the outcome is recorded — if you win, the charge is removed; if you lose, it stays on your account as a regular charge.
If Discover places a temporary credit on your account, that money counts toward your available credit during the investigation. If the dispute is later denied and the temporary credit is removed, your available credit will decrease again. This can affect your credit utilization ratio, which is part of your credit score calculation, but only temporarily. Once the dispute is fully resolved, your account returns to normal.
Frequently Asked Questions
How long do I have to report a dispute to Discover?
You have 60 days from the date the charge appeared on your statement to report it to Discover. After 60 days, Discover may not be able to investigate. If you spot an error on an older statement, contact Discover anyway — they may still help, but the window for a formal dispute has closed.
Can I dispute a charge if I authorized the transaction but the merchant charged me the wrong amount?
Yes. If you authorized a $50 purchase but were charged $75, that is a billing error and a valid dispute. Bring your receipt or confirmation showing the correct amount, and Discover will investigate. The merchant will need to explain why the charge differed from what you agreed to.
What if the merchant goes out of business before Discover finishes investigating?
Discover will still investigate and may still rule in your favor. A closed business does not automatically mean the charge is valid. If Discover determines the charge was unauthorized or fraudulent, they will remove it even if the merchant is no longer operating. If the merchant straightforward cannot be reached, Discover may rule based on the evidence you provide.
Do I have to pay the disputed amount while Discover investigates?
No. If Discover places a temporary credit on your account, you do not owe that amount while they investigate. If no temporary credit is issued, you still do not have to pay the disputed portion — contact Discover to confirm what you owe on the rest of your bill. Paying a disputed charge does not hurt your case, but it is not required.
Can I dispute a charge through Discover's website, or do I have to call?
You can do either. Log into your Discover account online and look for a "Report a Problem" or "Dispute a Transaction" option, or call the number on the back of your card. Both methods start the same investigation process. Online disputes may be faster if you have all your documentation ready to upload.
