How to start a dispute with Discover

Contact Discover directly by phone, online, or mail within 60 days of when you first noticed the charge. Discover's fraud department is reachable at the number on the back of your card. You can also log into your online account, go to the transaction in question, and select "Report a Problem" next to the charge. Have your card number, the transaction date, the merchant name, and the amount ready when you call.

Discover will ask you to describe what went wrong — whether the charge was unauthorized, the merchant billed you twice, the amount was wrong, or you never received what you paid for. Be specific about what happened and what you expect as a resolution. Discover may ask you to provide supporting documents like receipts, emails from the merchant, or proof that you returned an item.

Once you file a dispute, Discover will assign it a case number and send you written confirmation. Keep this number and all related documents. Discover has up to 90 days to investigate, though most disputes are resolved faster.

Key Takeaways

  • You have 60 days from the date you first saw the charge to report it to Discover, either by phone, online account, or mail.
  • Describe exactly what went wrong — unauthorized use, duplicate billing, wrong amount, or merchandise not received — and say what resolution you want.
  • Discover will temporarily credit your account while investigating, and you are not responsible for the disputed amount during that time.
  • Keep your case number and all documents you send to Discover, including receipts, emails, and proof of return.
  • If Discover rules against you, you can ask them to reconsider if you have new evidence.

What happens to your account while Discover investigates

Discover will usually place a temporary credit in your account within two to three business days of opening the dispute. This credit is not final — it is a provisional adjustment while Discover gathers information from you and the merchant. You can use this credit to pay your bill or make purchases, but understand that if Discover later decides the charge was valid, they will remove the credit and you will owe the amount again.

You are not responsible for paying the disputed charge while the investigation is open. Do not ignore the bill or assume the dispute means you do not owe anything. Continue paying the rest of your balance on time to avoid late fees or damage to your credit score.

What Discover asks merchants to prove

When you dispute a charge, Discover contacts the merchant and asks them to provide evidence that the transaction was legitimate. For unauthorized charges, the merchant must show proof you authorized the purchase — usually a signed receipt, a PIN entry, or a digital signature. For duplicate charges, they must explain why two identical or similar charges appear. For wrong amounts, they must show the original authorization you signed.

If the merchant cannot provide this proof, Discover will rule in your favor and the temporary credit becomes permanent. If the merchant does provide proof, Discover will send you their evidence and explain why they are closing the dispute. At that point, you can ask Discover to reconsider if you believe the evidence is forged, incomplete, or does not actually prove the charge was valid.

Disputes for items you never received or that arrived damaged

If you paid for something that never arrived or came damaged, tell Discover exactly what you ordered, when you expected to receive it, and what condition it was in when it arrived. Include any tracking information, delivery confirmation, or photos of damage. Discover will ask the merchant to provide proof of delivery or explain the damage claim.

For items that never arrived, the merchant must show a delivery confirmation with your signature or address. If the merchant cannot prove delivery, Discover will rule in your favor. If they can prove delivery but you genuinely did not receive the package, you may need to file a separate claim with the shipping carrier. For damaged items, photos are the strongest evidence — take clear pictures showing the damage before you open or use the item further.

What to do if the merchant refuses to cooperate

Some merchants ignore Discover's requests for documentation or refuse to respond. If this happens, Discover will note the merchant's non-response in your case file. A merchant's silence or refusal to provide proof often results in a dispute ruling in your favor, because Discover cannot confirm the charge was valid.

If you have already tried to resolve the issue directly with the merchant — by email, phone, or written letter — include copies of those communications when you file your dispute with Discover. This shows you made a good-faith effort and strengthens your case if the merchant later claims they never heard from you.

How to gather evidence before you dispute

Before contacting Discover, collect everything related to the transaction. This includes your original receipt, any confirmation emails from the merchant, your shipping confirmation and tracking number, photos of the item or packaging, and any written communication with the merchant about the problem. If you returned an item, get a receipt or tracking number showing the return was delivered.

If the charge is for a service you did not receive, document when you tried to use it, what error message or problem you encountered, and any emails or chat logs with customer support. Screenshots are helpful — take them before the merchant deletes the page or closes your account. The more specific your evidence, the faster Discover can resolve your dispute.

What happens if Discover rules against you

If Discover decides the charge was valid, they will remove the temporary credit from your account and you will owe the full amount again. Discover will send you a written explanation of their decision, including the merchant's evidence and why it satisfied their requirements. You have the right to ask Discover to reconsider if you have new evidence — for example, if you later receive a refund email from the merchant or discover the merchant's proof was forged.

If you still disagree with Discover's decision, you can file a complaint with the Consumer Financial Protection Bureau (CFPB), which oversees credit card disputes. The CFPB does not overturn Discover's decision, but it investigates whether Discover followed the law and can order them to correct errors in how they handled your case. You can file a complaint at consumerfinance.gov.

Frequently Asked Questions

What is the time limit to dispute a charge?

You have 60 days from the date the charge first appeared on your statement or account to report it to Discover. If you miss this deadline, Discover may still investigate if you have a strong reason for the delay, but you are not may provide protection. Mark your calendar or set a phone reminder if you notice a suspicious charge.

Can I dispute a charge if I authorized it but changed my mind?

No. Discover's dispute process is for unauthorized charges, billing errors, and merchandise problems — not for buyer's remorse. If you authorized a purchase and later decided you did not want it, contact the merchant directly to request a refund or return. If the merchant refuses, you may have other options depending on the merchant's return policy, but Discover will not overturn an authorized charge simply because you changed your mind.

Will disputing a charge hurt my credit score?

Filing a dispute does not directly hurt your credit score. However, if you stop paying your bill while the dispute is open, late payments will damage your score. Continue paying the rest of your balance on time. If Discover rules against you and you do not pay the charge, that unpaid balance can be reported to credit bureaus.

How long does a dispute investigation take?

Discover has up to 90 days to investigate, but most disputes are resolved within 30 to 45 days. You will receive updates by mail or through your online account as the investigation progresses. Once Discover makes a decision, they will notify you in writing with an explanation and the final outcome.

Can I dispute a charge if I used a debit card instead of a credit card?

Discover also issues debit cards, and the dispute process is similar but has different timelines and protections. For debit card fraud, you have 60 days to report unauthorized charges, but the sooner you report it, the better. Contact Discover's debit card fraud line using the number on the back of your card.
