To dispute a transaction on your credit or debit card, contact the card issuer or bank that holds the account, not the merchant, and do it within 60 days of the statement date that shows the charge. For a credit card, federal law requires that dispute in writing. For a debit card, a phone call is enough to start the process, though the bank can ask you to follow up in writing within 10 business days. The card type determines your deadline mechanics, your liability if things go wrong, and how quickly the bank has to answer you.
The 60-Day Clock
Most disputes are lost before they’re filed, because the reporting window ran out.
For a credit card, the written billing error notice must reach your issuer no later than 60 days after the issuer sent the first statement showing the charge.1Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution The clock runs from when the statement was transmitted, not from when you opened it.
For a debit card, the outer deadline is also 60 days from the statement, but a second, much shorter clock runs alongside it. If your card or card number was lost or stolen, notifying the bank within two business days of learning about it caps your liability at $50. Wait longer, and the exposure jumps.2eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers With a debit card, the safest move is to report the moment you spot the problem.
Try the Merchant First for Quality Problems
If the item arrived broken, never arrived, or wasn’t what was described, contact the seller before you call the bank. For credit card quality disputes, federal law actually requires that you make a genuine effort to work it out with the merchant first. The transaction must also exceed $50 and must have taken place in your home state or within 100 miles of your billing address.3Office of the Law Revision Counsel. 15 USC 1666i – Assertion by Cardholder Against Card Issuer of Claims and Defenses Those geographic and dollar limits can be a real problem for online purchases from unrelated retailers.
Quality claims are a credit card protection only. The Electronic Fund Transfer Act does not give debit card users an equivalent right to withhold payment over a product complaint. Unauthorized charges and billing errors on a debit card are still disputable; a “the sweater looked better online” claim is not.
For simple billing errors and outright fraud on either card type, you can skip the merchant and go straight to the bank.
How to File the Dispute
Credit Cards Require Writing
A phone call to your credit card issuer does not trigger the Fair Credit Billing Act’s protections. The law requires written notice.1Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution Some issuers accept online portal submissions as written notice, but only if the issuer has specifically said so. If you’re not sure, mail a letter.
Send it to the address the issuer designated for billing inquiries, which is almost never the payment address. Look for it on your monthly statement or in your cardholder agreement. Notice sent to the wrong address may not count, because the statute requires receipt at the designated address. Certified mail with return receipt gives you proof of delivery and the date.
Debit Cards Accept Either Method
The Electronic Fund Transfer Act accepts oral or written notice to open the investigation. A phone call kicks off the bank’s obligations. But the bank can require you to send written confirmation within 10 business days of that call. If you don’t, the bank is no longer required to provisionally credit your account while it investigates.4Office of the Law Revision Counsel. 15 USC 1693f – Error Resolution
What Your Notice Should Say
The notice needs to do three things: identify you and the account, describe the error and the dollar amount, and explain why the charge is wrong.1Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution Include the transaction date and the merchant name exactly as it appears on your statement, which often differs from the storefront name.
Attach whatever you have. Receipts, order confirmations, delivery tracking, screenshots of the product listing, photos of damaged goods, and any records of your attempts to resolve it with the merchant, including emails, chat transcripts, or notes with the representative’s name and date. Evidence that you tried to work it out first tends to help.
How Much You Can Actually Lose
The card in your wallet decides your exposure.
Credit cards cap your liability at $50 for unauthorized use, regardless of when you report, as long as the issuer met its disclosure obligations.5eCFR. 12 CFR 1026.12 – Special Credit Card Provisions Most major issuers waive even that $50 through zero-liability policies.
Debit cards use a tiered scheme that gets worse the longer you wait:
- Reported within 2 business days of learning of the loss: liability capped at $50.
- Reported after 2 business days but within 60 days of the statement: liability up to $500.6Consumer Financial Protection Bureau. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Reported more than 60 days after the statement: unlimited liability for unauthorized transfers that occur after the 60-day window closes.2eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
A stolen debit card number that drains a checking account can trigger bounced payments, overdraft fees, and missed bills. A fraudulent credit card charge doesn’t touch your cash. If you carry both, that gap is worth remembering at checkout.
What Counts as a Dispute
Federal law recognizes three categories, and framing the problem correctly keeps it from being kicked back on a technicality.
Billing errors. Charges for purchases you didn’t make, charges in the wrong amount, charges for items never delivered or refused, payments the issuer didn’t credit, and math mistakes on the statement.7Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Unauthorized charges. Someone used your card without permission, whether through a stolen number, a skimmer, or a fraudulent online purchase.
Quality and delivery problems. Credit cards only, subject to the merchant-contact, $50, and 100-mile rules above.
What Happens While the Bank Investigates
Once your credit card issuer receives a valid written notice, protections kick in automatically. You don’t have to pay the disputed amount or related finance charges while the investigation runs, and the issuer can’t try to collect them.8eCFR. 12 CFR 1026.13 – Billing Error Resolution Keep paying anything else on your balance so you don’t rack up late fees on undisputed charges.
Your issuer cannot report the disputed amount as delinquent to credit bureaus during the investigation.9Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports It cannot close or restrict your account just because you filed the dispute, though it can reduce your available credit by the disputed amount.8eCFR. 12 CFR 1026.13 – Billing Error Resolution
Credit Card Timeline
The issuer must acknowledge your written notice within 30 days of receiving it, unless it resolves the dispute inside that window. The full investigation must finish within two billing cycles and no longer than 90 days from receipt.7Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Debit Card Timeline
The bank must investigate and reach a determination within 10 business days of receiving your notice.4Office of the Law Revision Counsel. 15 USC 1693f – Error Resolution If it needs more time, it can extend to 45 days, but only by provisionally crediting your account for the disputed amount within those first 10 business days and notifying you within two business days of posting the credit.10Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors You get full use of the provisional funds during the investigation. Once the bank confirms an error, it must correct the account within one business day and report the results to you within three business days.
If Your Dispute Is Denied
A denial isn’t the end.
For a credit card dispute, the issuer must send a written explanation. You have the right to request copies of the documentary evidence the issuer relied on.7Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors Reviewing it sometimes shows the investigation missed something or that merchant information can be rebutted. If the amount remains in dispute after the investigation, the issuer can report it to credit bureaus only if it simultaneously notes that the amount is disputed, and it must tell you which bureaus received the report.9Office of the Law Revision Counsel. 15 USC 1666a – Regulation of Credit Reports
For a debit card denial where provisional credit was issued, the bank will debit those funds back from your account. It must keep honoring checks, scheduled transfers, and preauthorized payments for five business days after notifying you of the reversal, without charging overdraft fees on those items.10Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors Five days passes fast, so plan to move money in.
If you think the denial was wrong, file a complaint with the Consumer Financial Protection Bureau. The CFPB forwards it to the financial institution, which generally has 15 days to respond and up to 60 days for complex issues.11Consumer Financial Protection Bureau. Learn How the Complaint Process Works It doesn’t guarantee a reversal, but it adds regulatory attention. Small claims court is another route for smaller amounts once you’ve exhausted the bank’s process.
