Quick answer
Good chargeback evidence connects a specific document to a specific problem. Start with the statement page showing the posted charge, then add the receipt or order record, a short timeline, and proof that fits your reason for disputing it. That proof might be a tracking history, a cancellation confirmation, a return receipt, photographs, or messages with the seller.
For a U.S. personal credit card, the formal billing-error process generally requires written notice to reach the card issuer within 60 days after the first statement containing the error was sent. A phone call or online report may open a case, but don't rely on either one alone if you want to use the written billing-error process.
This information is for U.S. consumers and isn't legal advice. Debit cards, prepaid cards, ACH transfers, peer-to-peer payments, and wires can have different rules and bank procedures.
Start with the payment method
"Chargeback" is a broad term. The procedure depends first on how you paid.
For a credit-card billing error, contact the issuer that provided the card. You generally don't send a consumer evidence file directly to Visa or Mastercard. The issuer reviews your account, explanation, and supporting records within the applicable card and network process.
Keep these distinctions in mind:
- The 60-day written-notice rule comes from the U.S. credit-card billing-error process described by the Federal Trade Commission's guidance on disputing credit-card charges. It isn't a universal deadline for every payment type.
- The seller's refund or return policy can help show what was promised and whether you followed the seller's instructions. It doesn't replace notifying the issuer.
- Network reason codes belong mainly to the issuer, merchant, and processor workflow. Describe what happened accurately instead of trying to guess a Visa or Mastercard code.
- A dispute isn't an automatic refund. The issuer can deny it when the evidence doesn't support the stated problem, the notice was late, or the issue doesn't fit the applicable process.
If the transaction used a debit card or another payment rail, contact that financial institution promptly and ask which error-resolution procedure applies. Don't automatically apply the credit-card 60-day rule.
Choose evidence that proves the actual problem
A receipt establishes that a purchase occurred. It doesn't, by itself, show that the order was never delivered, that the amount was posted twice, or that a subscription had been canceled.
The useful records vary with the facts:
| Dispute reason | Useful evidence | What the records should show |
|---|---|---|
| Unauthorized charge | Statement showing the transaction, your report to the issuer, security alerts, and relevant seller messages | You didn't authorize the charge and reported it through the issuer's fraud process |
| Item or service not received | Order confirmation, promised delivery date, tracking history, service appointment, and messages to the seller | The seller accepted payment but didn't provide the promised item or service |
| Item damaged or not as described | Product listing, invoice, photographs, inspection records, and written communication with the seller | The goods arrived damaged or materially differed from what was advertised |
| Wrong amount or duplicate charge | Statement, receipt, checkout total, and proof of any other payment | The posted amount or number of charges doesn't match the transaction |
| Returned item or missing credit | Return authorization, shipping receipt, carrier scan, refund confirmation, and later statement | You returned the item or were promised a credit, but the credit wasn't posted |
| Subscription charged after cancellation | Terms shown at signup, cancellation confirmation, cancellation date, and later statements | A recurring charge continued after a documented cancellation |
| Billing fee or payment error | Statements, payment confirmations, bank records, and the issuer's or seller's explanation | The amount or fee is inaccurate, duplicated, or contradicted by the payment records |
Issuer forms may use different labels for similar problems. Don't force the facts into a category that doesn't fit. State what happened, when it happened, and what correction you're asking for.
For an unauthorized transaction, report it to the issuer promptly and follow any fraud affidavit or account-security instructions. For a delivery, quality, return, or billing problem, contact the seller as soon as practical and keep the response. The FTC says seller contact may help, but an unresolved conversation doesn't extend the issuer's deadline.
Arrange the file so the key facts are easy to find
A reviewer shouldn't have to search through a long email chain to locate the charge or understand the complaint. Put the documents in a sensible order:
- Short summary: Identify the merchant, amount, transaction date, statement date, and exact reason for the dispute.
- Statement page: Highlight the posted charge. Include enough information to identify the account, but redact unrelated transactions.
- Transaction record: Add the receipt, order confirmation, invoice, or subscription record.
- Chronology: List the purchase, promised delivery or service date, seller contact, return or cancellation date, and outcome.
- Direct proof: Attach the tracking history, photographs, cancellation record, refund message, payment record, or other document that proves the stated problem.
- Seller contact history: Include relevant emails, chats, and support-ticket numbers in date order.
Copies are usually sufficient. Hold on to the originals, including emails, photographs, tracking pages, and receipts, in case the issuer asks for them later. If you upload the file, save the confirmation page, submission date, and case number.
Protect your account information. Don't send a full card number, online-banking password, Social Security number, or unrelated account records unless the issuer specifically requests them through a secure channel. Use the issuer's secure upload system when available.
Write a focused dispute letter
The FTC's sample letter for disputing credit and debit card charges shows the basic information to include. Use your own facts rather than choosing a description that sounds stronger but isn't accurate.
A useful letter identifies the charge, states the error in one sentence, gives a dated explanation, and lists the attached proof:
Subject: Billing-error dispute for [merchant], [amount], [date]
I am writing to dispute a charge of [amount] posted by [merchant name] to my [card account or last four digits] on [date].
This charge is a billing error because [state the specific reason, such as "the order was not delivered" or "I was charged twice for one purchase"].
The relevant facts are: [give a brief, dated timeline].
I contacted the merchant on [date] by [email, phone, chat, or other method]. The result was [describe the response, refund promise, or lack of resolution].
Please investigate the charge and correct the error. I have enclosed copies of [list the documents].
[Your name]
[Mailing address]
[Phone or email]
[Account identifier requested by the issuer]
Send the notice to the issuer's address for billing inquiries or billing-error disputes. That address may differ from the address used for payments. If you mail the letter, keep a copy and proof of delivery. If the issuer accepts submissions through a secure online system, save the upload confirmation and date submitted.
Credit-card deadlines to put on your calendar
Use the first statement containing the error as the starting point. The relevant date is when that statement was sent, not necessarily the date of the purchase.
According to the FTC's guidance:
- Written notice: The issuer must receive the dispute within 60 days after the statement containing the error was sent.
- Acknowledgment: The issuer generally must acknowledge the complaint in writing within 30 days, unless it has already resolved the problem.
- Resolution: The issuer generally must resolve the dispute within 90 days after receiving the complaint.
Begin collecting records as soon as you notice the problem. A seller's promise that a refund is coming doesn't stop the issuer's clock. Keep the promise, watch for the credit on your statement, and send the issuer written notice before the 60-day period ends if the charge remains unresolved.
These are credit-card billing-error time frames. A merchant's response deadline, a debit-card investigation period, and an electronic-transfer deadline can be different.
If the issuer denies the dispute
Read the denial before adding more documents. The reason usually points to the issue that needs to be addressed: late notice, evidence that the transaction was authorized, proof of delivery, or a mismatch between the claim and the records.
Then:
- Keep the case number. Use it on every follow-up.
- Ask what evidence was considered. Request the written explanation and ask for copies of relevant merchant records the issuer relied on, such as a delivery record, signed receipt, or transaction record.
- Answer the stated reason. For non-delivery, identify the promised delivery date and tracking history. For a cancellation dispute, provide the cancellation confirmation and show the later charge. Don't bury the answer in a new collection of unrelated files.
- Ask about reconsideration or appeal. Follow the issuer's procedure and any deadline in the denial letter.
- Complain about poor handling separately. First make a formal complaint to the issuer. If the problem is with the bank or card issuer and remains unresolved, USA.gov's bank and credit complaint guidance directs consumers to available complaint options, including the Consumer Financial Protection Bureau.
A complaint about the issuer's conduct doesn't automatically remove the charge. It creates a separate record, so include the case number, submission dates, letters, and response.
What merchant and network records mean
Consumers usually don't need to obtain IP logs, device fingerprints, or processor reports. Those are typically merchant-side records, and the issuer may obtain or evaluate them during its review.
Visa's chargeback overview gives examples of merchant evidence such as receipts, shipping confirmations, and customer communications. If you're dealing with a merchant response, remember that the consumer's 60-day written-notice period isn't the merchant's representment deadline. Merchant deadlines and required documents come from the relevant issuer, acquirer, processor, network rules, and dispute category.
Mistakes that weaken a dispute
- Waiting for the seller: A promised refund or lengthy seller investigation doesn't extend the issuer's deadline.
- Using the wrong payment procedure: Don't use the credit-card billing-error timeline for a debit, ACH, peer-to-peer, wire, or prepaid transaction without checking first.
- Describing the issue vaguely: "This is fraud" doesn't explain a late delivery, duplicate charge, canceled subscription, or incorrect amount.
- Sending only the receipt: The receipt proves the purchase, not necessarily the error.
- Leaving out dates: Include the purchase, promised delivery, cancellation, return, refund, and seller-contact dates that matter.
- Submitting a large but unfocused file: A few documents tied directly to the stated reason are more useful than pages of unrelated correspondence.
- Sharing too much personal data: Redact full card numbers and unrelated account information.
- Disputing a pending authorization as a completed charge: Check whether the transaction has posted. Report suspected fraud promptly even if it is still pending.
Do this next
Find the first statement that shows the charge and write down the date it was sent. Pull out the statement page, receipt or order record, and the two or three documents that directly prove what went wrong. Then confirm the issuer's billing-dispute address or secure submission method, send the written notice before the 60-day period expires, and save proof that the issuer received it.
