When you notice an unauthorized or incorrect charge on your Discover credit card statement, federal law gives you specific rights to challenge it. The Fair Credit Billing Act (FCBA) protects cardholders by establishing a formal process for disputing charges. This law applies to all credit card issuers, including Discover, and requires them to investigate your claim within specific timeframes.

Your right to dispute charges covers several situations: charges you didn't authorize, charges posted twice by mistake, charges for items or services you never received, charges that don't match what you agreed to pay, mathematical errors on your statement, and charges that show incorrect amounts. Understanding which category your disputed charge falls into helps you present a stronger case and explains why the investigation matters.
Discover must acknowledge receipt of your dispute within 30 days of when you submit it. The company then has up to 90 days to investigate and respond with their findings. During this investigation period, the disputed amount cannot be reported as late, and creditors cannot try to collect it. This protection gives you breathing room while the claim is being reviewed.
It's important to know that disputing a charge does not mean you're automatically right or that Discover will rule in your favor. The investigation involves reviewing documentation from both you and the merchant. However, the burden falls partly on Discover to verify that the charge was legitimate and properly authorized. If they cannot prove the charge was valid, they must remove it from your account and credit your account.
Practical Takeaway: Write down the details of any charge you plan to dispute before contacting Discover—the date, amount, merchant name, and why you believe it's incorrect. This information will be essential when you file your dispute.
Starting a dispute with Discover involves several methods, each designed to create a record of your complaint. You can dispute a charge by phone, through your online account, by mail, or through Discover's mobile app. Whichever method you choose, Discover must treat it as a formal dispute under federal law as long as you contact them within 60 days of when the charge appeared on your statement.

If you call Discover's customer service, have your card number, the disputed charge details, and a brief explanation of why you're disputing it ready. The representative will ask you questions about the charge and may request documentation. Request a confirmation number for your dispute and ask about the investigation timeline. Many customers prefer calling because they can discuss the issue in detail and get immediate answers to their questions.
Disputing through your online account or mobile app offers convenience and creates a written record automatically. Log into your Discover account, locate the transaction, and select the dispute option. You'll answer questions about why you're disputing the charge and may be asked to provide supporting documents. The system will show you a reference number for tracking purposes. This method is useful if you prefer not to speak with someone directly or if you're disputing the charge outside of business hours.
Sending a written dispute by mail provides the most formal documentation. Write a letter to Discover that includes your name, card number, the disputed transaction details (date, amount, merchant), why you're disputing it, and copies of any supporting documents. Send it to the billing inquiries address listed on your statement or Discover's website. Use certified mail with return receipt to prove Discover received your dispute. Keep a copy for your records.
Regardless of which method you use, Discover must treat your communication as a formal dispute if you contact them within 60 days of the statement showing the charge. This deadline is crucial—disputes filed after 60 days may not receive the same legal protections.
Practical Takeaway: Choose the dispute method that creates the clearest written record. While phone calls are convenient, written disputes through mail or online channels provide documentation you can reference later if needed.
The strength of your dispute depends heavily on the evidence you provide. Documentation shows Discover that you're serious about your claim and gives them concrete reasons to side with you. The types of documents you need depend on your specific dispute, but having thorough records significantly increases your chances of a favorable outcome.

For unauthorized charges, collect evidence that you didn't make the purchase. This might include statements showing you were in a different location when the charge occurred, records proving you were traveling and couldn't have used your card in person, or communications showing you never approved the transaction. If someone fraudulently used your card, a police report about identity theft or fraud strengthens your case considerably.
For charges you claim you never received goods or services for, gather proof of non-delivery. This includes email confirmations showing expected delivery dates that passed, tracking information showing the package was returned to sender, photos of the empty package, or correspondence with the merchant discussing the missing item. Screenshots of your online order showing what was supposed to be delivered are valuable.
For billing errors or duplicate charges, your statement itself is key evidence. Highlight the charges in question, calculate the errors, and show the math clearly. If a charge appears twice, mark both instances. If the amount is wrong, show what you agreed to pay versus what was charged. Keep the original receipt or confirmation email from your purchase showing the correct price.
For quality or service disputes, document what went wrong. This might include photos showing a defective item, email exchanges with customer service where you reported the problem, receipts showing what you paid, or written descriptions of the service you didn't receive. Some disputes involve partially rendered services—for example, a contractor who didn't complete all agreed-upon work. Documentation of what was and wasn't done matters in these cases.
Keep digital copies of everything you send to Discover. Save emails, screenshots, photos, and documents to a folder on your computer or cloud storage. This allows you to reference your documentation if Discover asks follow-up questions or if you need to escalate your dispute.
Practical Takeaway: Before disputing a charge, gather every piece of evidence related to it, even if you're not sure whether it will help. Let Discover determine what's relevant rather than second-guessing yourself.
Once you file your dispute, Discover begins a structured investigation. The process varies slightly depending on the type of dispute, but federal law establishes clear requirements for how thoroughly Discover must investigate. Understanding what happens during this investigation helps you know what to expect and when you might receive a resolution.

Discover contacts the merchant whose name appears on the charge and requests documentation proving the charge was legitimate. This documentation typically includes the authorization record showing you approved the charge, proof that you received the goods or services, and any communications related to the transaction. The merchant has a limited time to respond to Discover's inquiry. If they don't respond within a certain period or cannot provide adequate proof, Discover is more likely to rule in your favor.
Discover also reviews the transaction details you provided in your dispute. They examine whether you provided the card yourself, whether the charge matches your account's history, and whether your claim is consistent with what you've said. If you claim the charge is unauthorized but your account shows a history of similar charges, Discover investigates more carefully whether this particular charge was truly unauthorized.
During the investigation, Discover may contact you for additional information. If they do, respond quickly. Delays in providing requested information can extend the investigation timeline. Be clear and factual in your responses, and avoid exaggerating your claim or providing contradictory information.
The investigation period lasts up to 90 days, though many disputes resolve faster. Discover will send you a written explanation of their findings. If they determine the charge was unauthorized or the merchant cannot prove it was valid, they'll remove the charge from your account and credit the amount. If they determine the charge was valid, they'll explain why and the amount will remain on your account. Either way, you have the right to review their decision and respond if you disagree.
During the investigation, the disputed amount is not counted against your credit limit in terms of whether you can use it. However, the charge may still appear on your credit report. Once the dispute is resolved in your favor, Discover removes it entirely from your credit history.
Practical Takeaway: Don't be surprised if Discover contacts you for more information during the investigation. Responding promptly and thoroughly helps move the process forward faster.
