For a U.S. credit-card dispute, start by naming the problem. The strongest evidence ties one specific charge to one specific failure: you didn't authorize it, the amount is wrong, a payment or refund is missing, or the goods or services weren't delivered as agreed.
A well-organized packet helps, but it doesn't extend the federal deadline. Under the Fair Credit Billing Act (FCBA) process, your written notice generally must reach the card issuer within 60 days after the first statement showing the error was sent. The Federal Trade Commission's credit card guidance describes the consumer process. Regulation Z, 12 CFR 1026.13 contains the billing-error rules.
First identify the type of dispute
An unfamiliar charge isn't necessarily fraudulent. Before reporting a transaction as unauthorized, check the merchant descriptor, receipts, household purchases, subscriptions, and digital-wallet activity.
The reason matters because each type of dispute calls for different records:
- Unauthorized use: You didn't make or approve the transaction. A household member's actual, implied, or apparent authority to use the account can affect the analysis.
- Wrong amount or duplicate charge: The statement doesn't match the agreed price, or the same purchase appears more than once.
- Payment or refund not credited: You made a payment or received a merchant credit, but it hasn't appeared on the account.
- Goods or services not received as agreed: The seller didn't deliver what was promised, or didn't deliver it by the agreed method or date. Whether the federal billing-error rules apply depends on the facts and applicable conditions.
- Recurring charge after cancellation: A subscription or membership charge continued after you canceled under the applicable terms. Keep the cancellation proof and identify every later charge.
Simply regretting a purchase doesn't automatically create a federal billing error. For a quality, return, or cancellation dispute, show what the seller promised, what you did to resolve the problem, and how the transaction failed to match that agreement.
The issuer handles the cardholder dispute under federal rules, the account agreement, and applicable card-network procedures. A network chargeback is generally the back-end process in which the issuer asks the merchant for information. The FTC isn't a chargeback judge, and Visa or Mastercard doesn't provide one universal consumer evidence checklist.
Evidence to gather for each charge
| Dispute reason | Useful evidence | Detail that matters |
|---|---|---|
| Unauthorized transaction | Statement, transaction details, fraud-report confirmation, card-lock or replacement record, and a short signed account of what happened | Say when you noticed the charge and whether the physical card was lost, stolen, or still with you |
| Wrong amount or duplicate | Receipt, invoice, order confirmation, checkout screen, and merchant correspondence | Compare the amount, date, currency, and number of charges |
| Payment not credited | Payment confirmation, bank or issuer receipt, payment date, and later statement | Include the amount and the account it was meant to pay |
| Goods or services not delivered | Order confirmation, promised delivery date, tracking history, cancellation request, and seller communications | Show the agreement and the actual result, rather than only saying you were dissatisfied |
| Refund or credit not posted | Merchant's refund confirmation, refund date and amount, return tracking, and the statement after the promised credit | Distinguish a promised refund from a message saying the merchant would merely review your request |
| Recurring charge after cancellation | Subscription terms, cancellation confirmation, timestamp, support messages, and later statements | Connect each post-cancellation charge to the date and method of cancellation |
| Unfamiliar merchant descriptor | Statement, merchant contact information, receipt, and records of household or wallet activity | Confirm the descriptor before treating the transaction as fraud |
A statement screenshot answers one question: did the charge appear? It usually doesn't answer why the charge is wrong. Add the document that connects the entry to the problem.
Turn the records into an evidence packet
Put the documents in a date order that another person can follow without rebuilding the story.
- Save the statement. Download the original PDF or image showing the statement date, merchant, transaction date, and amount. Highlight the disputed entry.
- Write a timeline. Include the purchase, delivery or cancellation date, contacts with the merchant, the date you discovered the problem, the date you reported it to the issuer, and any promised refund date.
- Add transaction-specific records. Use the receipt, order page, contract terms, tracking information, payment confirmation, or refund notice that supports your stated reason.
- Preserve communications. Save emails and chat transcripts. After a phone call, record the date, number called, representative's name if available, and what the representative promised.
- Ask for a specific correction. State whether you want the charge removed, the duplicate reversed, the payment credited, or the disputed amount investigated.
- Remove unnecessary sensitive information. Redact unrelated transactions, your full card number, security codes, and Social Security number. Leave enough information for the issuer to identify the account and charge.
Name files by date and purpose, such as 2026-03-04_statement.pdf and 2026-03-05_merchant-refund-email.pdf. Keep the originals and send copies unless the issuer specifically requests an original.
Do you need an affidavit?
No single federal rule requires every cardholder to submit a notarized affidavit. An issuer may send a fraud questionnaire or request a signed statement, particularly for an unauthorized-use claim. Follow the issuer's instructions, and sign only facts you know are true.
A simple declaration could say:
I did not authorize the charge of $[amount] from [merchant] dated [date].
I did not give permission for this transaction to another person.
I discovered the charge on [date] and reported it to [issuer] on [date].
The facts above are true to the best of my knowledge.
Signature: [name]
Date: [date]Don't state that nobody in your household authorized a purchase unless you have a reasonable basis for saying so. The issuer may treat a transaction differently if another person had authority to use the account.
Send the written dispute before the deadline
Don't wait for the merchant to finish discussing the problem if the 60-day period is approaching. For the FCBA procedure:
- Use the issuer's billing-dispute address. It may not be the address used for payments. Check the statement, card agreement, or issuer's instructions.
- Make sure the notice arrives within 60 days. The period generally starts when the first statement containing the error was sent, not simply on the purchase date.
- Identify the charge precisely. Include your name, account identifier or last four digits, disputed amount, transaction date, merchant, statement date, and a clear explanation.
- Send copies of supporting records. Keep the letter, attachments, and proof of delivery.
- Call about urgent security problems, but don't rely on the call alone. Report suspected fraud immediately and ask the issuer to lock or replace the card. Then send the written notice required for the billing-error process.
If the statement went to an old address, the FTC says the issuer generally must have received your written change of address at least 20 days before the end of the billing period for the billing-error protections to apply. If you're unsure how to calculate the deadline, send the notice immediately.

The charge is an error because:
[Explain the facts clearly. For example: "I was charged twice for one purchase,"
"I paid this amount on [date] but it was not credited," or "The service was not

Please investigate this billing error under the Fair Credit Billing Act and
Regulation Z. Please correct the account if the error is confirmed and send me
the written result of your investigation.

[Your name]If you mail the notice, a trackable delivery method can help show when the issuer received it. If you use a secure upload or another electronic channel offered by the issuer, save the confirmation and follow any separate written-notice instructions.
What happens after the issuer receives the notice?
The FTC says the issuer generally must acknowledge your written complaint within 30 days, unless it has already resolved the issue. It generally must resolve the dispute within two complete billing cycles, and no later than 90 days after receiving the notice.
Pay the part of the bill that isn't disputed while the investigation is pending. Don't stop paying the entire balance because one charge is under review. Continue checking statements for credits, reversed charges, finance charges, and new transactions.
The FCBA deadline and a card-network deadline are different clocks:
| Step | What generally controls it |
|---|---|
| Your written billing-error notice | The FCBA and Regulation Z |
| The issuer's acknowledgment and investigation | Regulation Z timing rules |
| A merchant's response to a network chargeback | Card-network and processor procedures |
| A merchant refund | The merchant's refund terms and the issuer's posting process |
Visa's chargeback overview lists receipts, shipping confirmations, and customer communications as examples of evidence a merchant may use to challenge a dispute. That response belongs to the back-end network process. It doesn't replace your opportunity to explain why the amount, authorization, delivery, or refund is still wrong.
If the issuer denies the dispute
Read the written decision closely. The next useful document depends on the reason for the denial.
- Identify the finding. Did the issuer decide the charge was authorized, the goods were delivered, the merchant issued a credit, or the notice was late?
- Ask what records were relied on. Request the transaction information or merchant response supporting the decision, when available.
- Respond to that finding. For example, pair a delivery record with proof that the package went to the wrong address, or pair a refund promise with statements showing that no credit posted.
- Check the dispute category. A duplicate charge, missing refund, delivery problem, and unauthorized transaction need different evidence.
- Review the next statement. Check the disputed balance, any credit or reversal, finance charges, and the next payment due date. Keep paying amounts that aren't in dispute.
- Escalate a procedural problem. If the issuer ignored a timely written notice or missed required investigation steps, preserve the delivery proof and correspondence. You can consider a complaint to the Consumer Financial Protection Bureau or your state attorney general. A complaint doesn't guarantee a reversal, so keep the issuer's written review in the record.
Keep the statement, dispute letter, attachments, delivery confirmation, issuer responses, and later statements until the matter is resolved and any appeal or complaint is closed. For suspected identity theft, keep fraud and account-security records longer if the issuer or a government agency tells you to do so.
Evidence mistakes that weaken a dispute
- Sending only a screenshot with no explanation
- Mailing the notice to the payment address instead of the billing-dispute address
- Waiting for the merchant before sending a time-sensitive issuer notice
- Calling a charge fraud when the real issue is delivery, amount, cancellation, or a missing refund
- Omitting the statement date or the date you discovered the problem
- Sending blurry images or pages unrelated to the disputed charge
- Failing to check whether a household member or digital wallet authorized the transaction
- Stopping payment on the entire bill
- Sending originals without keeping copies
- Treating a phone promise as proof that the issuer received a written dispute
Frequently asked questions
Can screenshots and receipts alone win a dispute?
They can support a straightforward wrong-amount, duplicate, or non-delivery claim, but they may not answer every question. Add a short timeline and the relevant merchant communication when possible.
Can I dispute a charge after 60 days?
Contact the issuer anyway, especially if you suspect fraud. Missing the FCBA written-notice deadline can affect the federal billing-error procedure, but the issuer may still review the claim under its own policy or another applicable process.
Is calling the card issuer enough?
A call can secure the account and start the issuer's internal workflow. It isn't a substitute for the written notice used for the FCBA billing-error procedure, so send the written dispute promptly.
Does a merchant's refusal to refund settle the dispute?
No. It shows the merchant's position, not necessarily whether the charge was a billing error. Include the merchant's terms, your cancellation or return records, and the response you received.
Are debit-card disputes handled the same way?
No. Debit cards, prepaid cards, bank transfers, and peer-to-peer payments use different rules and deadlines. This guidance is for U.S. credit-card billing disputes.
Download the statement that first showed the charge, mark the exact transaction, and write the key dates before contacting the issuer.
