The short answer
For a U.S. consumer credit card, contact the issuer as soon as you identify an unauthorized charge or billing problem. If you’re using the Fair Credit Billing Act (FCBA) billing-error process, your written dispute generally must reach the issuer within 60 days after the first statement containing the error was sent.
Use the billing-inquiries address on your statement, not automatically the address used for payments. You can also open a case by phone or in your card app, but an online or phone report may not replace the required written notice. Follow the issuer’s instructions and keep proof of what you sent.
For a delivery, cancellation, or refund problem, contact the merchant too, but don’t wait for a response if the 60-day deadline is close. A chargeback isn’t an automatic refund. The issuer reviews the facts and may use the card network’s dispute rules to decide whether to reverse the transaction.
This guide covers U.S. consumer credit cards. Debit cards, ACH transfers, wire payments, peer-to-peer payments, and cryptocurrency use different rules and recovery processes.
First identify the type of problem
| Problem | Best first step | Key caution |
|---|---|---|
| A charge you didn’t authorize | Call the card issuer immediately and ask how to block or replace the card | Check quickly for an authorized user or recurring subscription, but don’t delay a fraud report |
| Wrong amount, duplicate charge, or missing payment credit | Send a written billing-error dispute to the issuer | Include the statement date, transaction amount, and a clear explanation |
| Goods or services never delivered | Contact the merchant, then notify the issuer | Save the promised delivery date, tracking information, and messages |
| A canceled service or promised refund never credited | Ask the merchant for written confirmation, then dispute the missing credit | Include the cancellation or refund date and any reference number |
| Damaged or misrepresented goods | Try to resolve the issue with the merchant and ask the issuer whether the transaction qualifies | A quality complaint alone doesn’t guarantee a chargeback |
| Debit, ACH, wire, P2P, or crypto payment | Contact the bank or payment provider that handled the payment | The FCBA credit-card process doesn’t apply |
An unfamiliar merchant name isn’t always fraud. It may be a parent company, payment processor, hotel group, or subscription renewal. Check the receipt and account history quickly. If you still didn’t authorize the transaction, report it to the issuer.
How to file a chargeback dispute step by step
1. Confirm that the transaction has posted
Check the statement for the merchant name, transaction date, posting date, amount, and currency. A pending authorization may disappear or change before it posts, although you should still report suspicious activity promptly.
Save a screenshot or PDF of the statement. Don’t rely on memory if the issuer later asks when you first saw the charge.
2. Protect the account if fraud is involved
Use the phone number on the back of the card or in the issuer’s official app. Ask whether the card should be frozen or replaced, and change the password for the card account if necessary.
For a lost or stolen physical credit card, federal law generally limits liability for unauthorized use to $50 in applicable situations. Unauthorized use of only the account number may be treated differently. Report the charge immediately instead of relying on a liability limit or a card’s voluntary zero-liability policy.
3. Contact the merchant when the dispute concerns a purchase
For non-delivery, cancellation, billing, or refund problems, send the merchant a short written request. State:
- What you ordered or paid for
- The transaction date and amount
- What went wrong
- The remedy you want
- A reasonable response deadline
Keep the email, chat transcript, return label, and any reply. Contacting the merchant can resolve the problem faster and gives the issuer a useful record, but it shouldn’t cause you to miss the issuer’s deadline. You don’t need to negotiate with a suspected fraudster before reporting unauthorized use.
4. Gather focused evidence
A clear timeline is usually more useful than a large folder of unrelated files. Include:
- The relevant card statement or transaction record
- Receipt, invoice, order confirmation, or booking record
- Merchant correspondence and your resolution request
- The merchant’s cancellation, return, delivery, or refund terms
- Photos showing damage or that the product differs from its description
- Shipping, tracking, return, or delivery records
- Proof of a refund, cancellation, or payment made by another method
- A police or identity-theft report, if you made one
Redact your full card number, passwords, and other sensitive information unless the issuer specifically requests it through a secure channel.
5. Send the dispute to the issuer
Use the issuer’s dispute form or app if it provides one, and send a written notice to the billing-error address when you’re relying on FCBA protections. Your notice should include:
- Your name and account information requested by the issuer
- The merchant’s name
- The transaction date and amount
- The statement date on which the error appeared
- A factual explanation of the problem
- The date and result of your contact with the merchant
- A list of attached documents
- The correction or investigation you’re requesting
Use accurate facts. Don’t label a purchase as “fraud” simply because the item was disappointing, and don’t claim non-delivery if tracking shows it was received.
The Federal Trade Commission’s guide to using credit cards and disputing charges includes billing-error instructions and a sample dispute letter.
6. Keep paying the undisputed balance
During a qualifying FCBA investigation, you generally don’t have to pay the disputed amount or related finance charges while the issuer reviews it. You still need to pay all other charges and required portions of the bill on time.
If the statement includes both disputed and undisputed amounts, ask the issuer how to calculate the payment. Don’t stop paying the entire account unless the issuer clearly confirms that no payment is required.
7. Respond to follow-up requests
The issuer may ask for a clearer explanation, proof that you contacted the merchant, delivery information, or documentation about an unauthorized transaction. Respond by the stated deadline and keep a copy of every submission.
A provisional credit is not always final. The issuer can remove it if the investigation finds that the charge was valid or the evidence doesn’t support the claim.
8. Review the written decision
Check whether the issuer:
- Corrected the balance
- Reversed the provisional credit
- Found that the issue wasn’t a qualifying billing error
- Relied on information from the merchant
- Asked for additional information
If the decision is unfavorable, request the written explanation and the documents used to reach it. Ask whether the issuer offers an appeal, reconsideration, or further card-network review, and note the deadline for that step.
Chargeback evidence checklist by dispute reason
| Dispute reason | Helpful evidence |
|---|---|
| Unauthorized transaction | Statement, fraud-report confirmation, account alerts, and information showing you didn’t make or approve the purchase |
| Wrong amount or duplicate billing | Receipt, invoice, order record, and a comparison showing the incorrect or repeated charge |
| Item not received | Promised delivery date, order confirmation, tracking record, and messages with the merchant |
| Service canceled | Cancellation confirmation, contract or booking terms, and proof the merchant didn’t provide the promised refund |
| Refund not posted | Merchant’s refund confirmation, refund reference number, original receipt, and later statements |
| Damaged or not as described | Listing or advertisement, photos, product details, return attempt, and merchant communications |
| Subscription problem | Cancellation request, terms shown at signup, renewal notice, and proof of the disputed renewal |
Write a short chronology with dates. For example: ordered, expected delivery, contacted merchant, requested cancellation, received refund promise, and saw the charge remain on the statement. The chronology helps the issuer connect each document to the dispute.
Chargeback deadlines: what actually controls
Several different deadlines can apply, so a generic “120-day chargeback rule” isn’t reliable for every Visa, Mastercard, or American Express transaction.
| Step | General U.S. consumer-credit rule or practice |
|---|---|
| Written FCBA billing-error notice | The issuer generally must receive it within 60 days after the first statement containing the error was sent |
| Issuer acknowledgment | The issuer generally must acknowledge the complaint within 30 days, unless it resolves the issue sooner |
| Issuer investigation | The issuer generally must resolve the dispute within two complete billing cycles, and no later than 90 days |
| Card-network dispute | The deadline depends on the reason, issuer, network, transaction type, and sometimes the expected delivery or service date |
| Merchant response | The acquirer or payment processor’s notice controls; the available window may be shorter than general network estimates |
Network rules and the FCBA are not the same thing. A network deadline may be measured from the transaction date, statement date, expected delivery date, or another event. The issuer’s notice and portal should state the deadline that applies to your case.
If you moved, the FTC says the issuer generally must have received your written change of address at least 20 days before the billing period ended for this billing-error process to apply.
If you missed 60 days, contact the issuer anyway and explain when you discovered the problem. The issuer may review the issue under a network rule or its own policy, but you shouldn’t assume the statutory billing-error protections remain available.
What happens if the merchant challenges the dispute?
A merchant can submit information through its acquiring bank or payment processor. The issuer may then ask you for a response or may make a final decision based on the records received.
A merchant’s response doesn’t automatically defeat your claim. Compare it with your own evidence and point out specific inaccuracies, such as:
- A delivery record for a different address
- A refund amount that doesn’t match the promised refund
- A cancellation policy that wasn’t disclosed at checkout
- A tracking record showing only shipment, not delivery
- A claim that the transaction was authorized even though the card was reported stolen
Send a concise response with documents that address the exact reason for the dispute. Avoid submitting multiple conflicting explanations.
If you’re the merchant responding to a chargeback
The deadline in the acquirer or processor notice controls. There is no universal 20-to-45-day response period that applies to every case, and the usable time may be shorter than a card-network timetable.
A useful representment packet should match the evidence to the reason for the dispute:
- Authorization and settlement records
- The order, invoice, or signed receipt
- The billing descriptor shown to the customer
- Delivery confirmation, tracking, or pickup records
- Refund, cancellation, and return records
- Relevant customer communications
- Terms accepted at checkout
- Fulfillment or access records for digital goods and services
- Address verification, card-security, or strong-authentication results when relevant
Explain the timeline in plain language. An IP address or login record may support a case, but it doesn’t by itself prove that the cardholder authorized the transaction. Don’t fabricate, alter, or backdate records, and remove unnecessary cardholder data before uploading evidence.
Payments that need a different dispute process
A credit card chargeback can’t be used automatically for every payment method.
- Debit cards: Report unauthorized activity to the bank immediately. Electronic-fund-transfer protections and deadlines differ from credit-card billing-error rules.
- ACH and bank transfers: Contact the bank or payment provider as soon as possible. Recovery may depend on whether the transfer was authorized and whether it has settled.
- Wire transfers: Ask the bank about a recall immediately, but a recall isn’t guaranteed.
- PayPal and marketplaces: Use the platform’s dispute system and check the transaction-specific deadline. A platform case and a credit-card dispute are separate processes.
- Stripe payments: Stripe may process the merchant’s payment, but consumers generally work through the merchant and the card issuer shown on the transaction record.
- Cryptocurrency: Blockchain transfers are generally not reversible through a card network. Contact the exchange or wallet provider quickly and preserve transaction details.
If a card funded a payment platform, ask the issuer which transaction it can review. Don’t seek duplicate refunds for the same loss without telling the parties involved.
Common mistakes that weaken a dispute
- Waiting for a merchant response until the 60-day notice period expires
- Sending the letter to the payment address instead of the billing-error address
- Describing the issue vaguely
- Guessing a Visa, Mastercard, or American Express reason code
- Calling a quality complaint “fraud”
- Disputing a pending authorization as though it were a completed charge
- Stopping payment on the entire statement
- Ignoring an issuer or merchant request for information
- Sending altered screenshots or incomplete records
- Filing overlapping claims without explaining the payment path
No universal consumer or merchant success rate applies. The result depends on the transaction, evidence, applicable law, issuer procedure, and card-network rules.
If the issuer denies the claim
Start with the denial letter, not a new dispute form. Ask the issuer for:
- The specific reason for the denial
- The evidence or merchant response it relied on
- The deadline and method for an appeal
- Whether the matter was reviewed under FCBA protections, network rules, or both
Submit a focused appeal that corrects the factual problem and adds only relevant evidence. If the issuer appears not to have followed the required billing-error procedure, you can escalate through its compliance or executive-resolution channel and consider filing a complaint with the Consumer Financial Protection Bureau. A regulator can review complaint handling, but it doesn’t guarantee a refund or decide every merchant-versus-customer factual dispute.
If the amount is substantial, review the card agreement and applicable local court or arbitration options before paying fees or accepting a settlement.
Frequently asked questions
Do I have to contact the merchant before filing?
Not for suspected fraud. Report unauthorized use to the issuer immediately. For delivery, cancellation, or refund issues, contacting the merchant is useful, but don’t delay the written issuer notice while waiting.
Can I file after 60 days?
You can still ask the issuer to review the transaction, especially if another network deadline may apply. However, missing the FCBA written-notice deadline can affect your statutory billing-error protections.
Will a chargeback always result in a refund?
No. The issuer may issue temporary credit, but it can reverse that credit after reviewing the merchant’s response and the available evidence.
Can I dispute digital goods or subscriptions?
Possibly. Evidence of non-delivery, unauthorized renewal, cancellation, or a missing refund may support a dispute. Mere dissatisfaction doesn’t automatically establish a billing error.
If a charge appears on a recent statement, find the issuer’s billing-inquiries address now, build a dated evidence list, and send the written notice before the deadline. This is general U.S. consumer information, not legal advice.
