How to dispute a charge on your Discover card
You can dispute a charge on your Discover card by calling Discover's dispute team, submitting a dispute through your online account, or using the Discover mobile app. Discover calls this process a chargeback or dispute claim. You have up to 120 days from the transaction date to file, though disputing sooner gives Discover more time to investigate. The process is free — Discover does not charge you to file a dispute.
Most disputes are resolved within 30 to 60 days, though complex cases can take longer. During the investigation, Discover will contact the merchant for their records and may ask you for documentation. You keep the disputed amount in your account while Discover investigates; you are not required to pay it back unless the investigation finds the charge was valid.
Key Takeaways
- You have 120 days from the transaction date to dispute a charge, but filing within 30 days gives Discover the most time to investigate.
- Call Discover at the number on the back of your card, log into your online account, or use the Discover app to start a dispute.
- Gather receipts, emails, or other proof of what happened — whether the charge was unauthorized, the merchant never delivered, or the amount was wrong.
- You do not pay the disputed amount while Discover investigates, and the process is free.
- If Discover rules against you, you can request that they reconsider if you have new evidence.
Reasons you can dispute a Discover charge
Discover accepts disputes for several categories of problems. Unauthorized transactions are charges you did not make or authorize — someone used your card number without permission. Billing errors include duplicate charges, charges for the wrong amount, or charges posted to your account twice. Merchandise not received means you paid for something that never arrived. Merchandise not as described covers situations where what you received does not match what the merchant promised — for example, a broken item, the wrong size, or a completely different product.
You can also dispute a charge if the merchant charged you after you cancelled a subscription or recurring payment. If a merchant promised a refund and never issued it, that is also a valid dispute reason. Discover will ask you to describe the problem in detail when you file, so be specific about what went wrong and when you discovered it.
Disputing through your Discover online account
Log into your Discover account at discover.com using your username and password. Go to the "Transactions" or "Activity" section and find the charge you want to dispute. Click on the transaction and look for a "Dispute" or "Report a Problem" button. Discover will ask you to select the reason for the dispute from a list — choose the one that matches your situation most closely.
You will then be asked to describe what happened in your own words. Be as detailed as possible: include dates, what you ordered or expected, and what actually occurred. If you have supporting documents — a receipt, an email confirmation, a tracking number showing the package was not delivered, or a photo of a damaged item — you can upload them at this stage. Discover will confirm your dispute has been filed and give you a reference number.
Disputing by phone with Discover
Call the number on the back of your Discover card and tell the representative you want to dispute a charge. Have your card number and the transaction details ready — the merchant name, the amount, and the date. The representative will ask you why you are disputing the charge and will record your explanation. They may ask follow-up questions to understand the situation better.
The representative will tell you what happens next and give you a dispute reference number. Write this number down and keep it somewhere safe. You can use it to check on the status of your dispute by calling back or logging into your account. Discover will send you written confirmation of the dispute by mail within a few days.
What Discover does during the investigation
Once you file a dispute, Discover contacts the merchant and asks them to provide proof that the charge was valid — typically a signed receipt, a delivery confirmation, or other documentation. The merchant has a set time to respond, usually 10 to 30 days depending on the type of dispute. If the merchant does not respond or cannot provide proof, Discover is more likely to rule in your favor.
Discover may also ask you for additional information during the investigation. If they do, respond as quickly as possible — delays can slow down the process. The investigation is free, and you do not have to pay the disputed amount while it is ongoing. Your credit report is not affected by filing a dispute.
What happens after Discover makes a decision
Discover will notify you in writing of the outcome, usually within 30 to 60 days of filing. If Discover rules in your favor, the charge is removed from your account and you owe nothing. If Discover rules against you, the charge stays on your account and you are responsible for paying it. Discover will explain their reasoning in the letter they send you.
If you disagree with Discover's decision, you can request reconsideration if you have new evidence — for example, a tracking number showing the package was never delivered, or a written statement from the merchant admitting the error. Contact Discover with this new information and ask them to reopen the dispute. There is no limit to how many times you can request reconsideration, but you will need new evidence each time.
How to prevent disputes in the future
Keep receipts for all purchases, especially online orders. Save confirmation emails from merchants that show what you ordered and the amount charged. For subscriptions and recurring charges, write down the cancellation date and keep any confirmation that the merchant sent you. Check your Discover statement every month and report any unfamiliar charges right away — the sooner you dispute, the stronger your case.
If you are buying from an unfamiliar merchant, use a credit card rather than a debit card when possible. Credit card disputes have stronger protections than debit card disputes. If a merchant seems unreliable or has poor reviews, consider using a different seller or paying through a service like PayPal that offers its own dispute process.
Frequently Asked Questions
What if the merchant says they already refunded me?
If the merchant claims they issued a refund but you never received it, that is still a valid dispute. Tell Discover the merchant promised a refund and the date they said they would send it. Discover will contact the merchant and ask for proof the refund was issued. If the merchant cannot prove it, Discover will likely rule in your favor.
Can I dispute a charge if I just changed my mind about the purchase?
Changing your mind is not a valid dispute reason on its own. However, if the merchant has a return policy and refused to honor it, or if you returned the item and they refused the return, you can dispute based on that. You will need to show Discover that you attempted to return the item or that the merchant violated their own policy.
How long does a dispute investigation take?
Most disputes are resolved within 30 to 60 days. Complex cases or situations where the merchant takes time to respond can take longer, up to 90 days in some cases. Discover will send you updates if the investigation is taking longer than expected. You can check the status anytime by logging into your account or calling the number on your card.
Will disputing a charge hurt my credit score?
No. Filing a dispute does not appear on your credit report and does not affect your credit score. Your credit is only affected if you fail to pay charges that Discover rules were valid. Disputing a charge is a normal part of how credit card protections work.
What if I do not recognize the merchant name on my statement?
Some merchants use different names on statements than they use in stores or online. Before you dispute, try to figure out what the charge is for — search the merchant name online, check your email for receipts, or look through your browser history. If you still cannot identify it and you did not authorize it, file a dispute for an unauthorized transaction. Discover will investigate and contact the merchant.
