For a U.S. credit card, you can ask the issuer to investigate a charge that appears to be a billing error. Common examples are an unauthorized transaction, a wrong or duplicate amount, or goods or services that weren't delivered as agreed.
The deadline is the part you can't safely ignore: your written notice generally must reach the issuer within 60 days after the first statement containing the error was sent. A dispute starts an investigation; it isn't an automatic refund. These rules apply to credit cards, not debit cards, prepaid cards, ACH transfers, wires, or peer-to-peer payments.
What "chargeback" means here
People often use "chargeback" to mean reversing or investigating a card transaction. The federal protections for a consumer credit card dispute come from the Fair Credit Billing Act and Regulation Z's billing-error rules.
The issuer is the bank or financial institution that provided the card. It reviews your notice and evidence. The merchant may submit its own information, but a merchant's return policy doesn't replace your duty to notify the issuer on time.
The rules below concern the U.S. credit-card billing-error process. They don't set merchant response deadlines or explain card-network arbitration rules. If the payment came from a debit card or another rail, use that provider's dispute process instead.
Which credit card charges can you dispute?
Under 12 CFR 1026.13, billing errors can include:
- An unauthorized transaction: The charge wasn't made by you or by someone authorized to use the account.
- An incorrect or duplicate amount: The amount or transaction shown on the statement doesn't match what you agreed to.
- An unidentified transaction: The statement doesn't properly identify the charge.
- Goods or services not received as agreed: An item or service wasn't delivered, or wasn't delivered according to the agreement.
- A payment or credit that wasn't posted: This can include a payment you made or a merchant refund that didn't appear on the account.
- A calculation or accounting error: The statement contains a mathematical or similar bookkeeping mistake.
A billing dispute isn't a general right to cancel a purchase. Changing your mind, disliking a correctly described product, or disagreeing with a clearly disclosed return policy may not be a billing error by itself. State what went wrong and connect that problem to the specific charge.
The FTC's guidance on goods you never received or unordered products has examples of the records that can help with those disputes.
The 60-day deadline
For the federal billing-error procedure, the issuer must receive your written notice no later than 60 days after the first statement with the error was sent to you. That usually means the statement date or mailing date, not the day you first noticed the charge.
Use the billing-inquiries or billing-disputes address on the statement or in the card agreement. The address for payments may go to a different department. Keep a copy of the notice and attachments, along with proof of when the issuer received them.
If you've changed your billing address, notify the issuer in writing and make sure it has the new address at least 20 days before the relevant billing period ends. Otherwise, the federal protections may be affected.
Suspected fraud should be reported to the issuer right away. For a delayed shipment, some issuers may extend the 60-day period, but confirm that with the issuer instead of assuming an extension applies.
The FTC's credit card dispute guidance also recommends written notice and describes the basic billing-error process.
How to file the dispute
1. Check the statement first
Before writing, gather:
- The merchant name as it appears on the statement
- The transaction date and amount
- The date the statement was sent
- The last four digits or other account identifier the issuer requests
- A plain description of why the charge is wrong
Check whether the transaction is pending, has already been refunded, or is part of a recurring payment. If a merchant promised a refund, keep that promise in writing and identify the missing credit in your notice.
2. Contact the merchant if that makes sense
A merchant may be able to fix a duplicate charge or issue a refund more quickly. Save the order confirmation, emails, chat messages, cancellation record, return tracking, and the dates and names connected with phone calls.
You don't have to wait forever for a merchant response. Contacting the merchant doesn't stop the issuer's 60-day written-notice deadline.
3. Send the issuer a written notice
Give the amount, transaction date, merchant, and reason for the dispute. A short timeline works better than a conclusion such as "fraud" on its own:
- You placed the order or made the payment.
- The merchant promised an item, service, delivery, or refund.
- The problem occurred.
- You contacted the merchant, if you did.
- You notified the issuer and supplied the records.
Ask the issuer to investigate the billing error and correct the account. Send copies, not originals.
An online form or phone call may open the issuer's internal case, but don't assume it replaces the written notice required for the federal billing-error process. If you submit the dispute online, save the confirmation and check whether the issuer also requires a letter sent to its billing-disputes address.
4. Pay the part you don't dispute
While the issuer investigates, you generally don't have to pay the disputed amount or related finance and other charges. You still need to pay all undisputed amounts by the due date. Ignoring the rest of the bill can create a separate payment problem.
5. Watch for the issuer's response
The issuer generally must:
- Acknowledge the written complaint within 30 days, unless it has already resolved the problem
- Resolve the dispute within two complete billing cycles, and no later than 90 days after receiving the notice
If the issuer finds an error, review a later statement to make sure the correction appears. If it rejects the dispute, read the explanation and request copies of the documents it relied on if they weren't provided.
Evidence to collect
The best evidence usually answers three questions: What did you agree to? What actually happened? When did you try to fix it?
| Dispute type | Useful evidence |
|---|---|
| Unauthorized charge | The statement, when you noticed the charge, messages with the issuer or merchant, and any relevant fraud report |
| Item never delivered | Order confirmation, promised delivery date, tracking history, delivery status, and your attempts to resolve the problem |
| Service or product not delivered as agreed | Receipt, listing or agreement, promised terms, relevant photos, and messages describing the mismatch |
| Incorrect or duplicate amount | Statement, receipt, invoice, checkout screen, and proof of the amount you actually authorized |
| Payment or refund missing | Payment confirmation, merchant refund confirmation, return records, and statements showing that the credit wasn't posted |
| Statement identification or accounting error | The statement page, your calculation of the error, and related receipts or account records |
Redact unrelated account numbers, passwords, and other sensitive information the issuer doesn't need. Keep the documents tied to the disputed transaction rather than sending a large collection of unrelated screenshots.
A billing-dispute letter template
Subject: Billing error notice for account ending in [last four digits]
I dispute a charge of $[amount] from [merchant] dated [transaction date], shown on the statement sent on [statement date].
The reason for my dispute is [unauthorized transaction, incorrect amount, duplicate charge, goods or services not received or not delivered as agreed, payment or credit not posted, or another billing error].
[Briefly describe what happened. Include the relevant dates and the amount that should have appeared on the account.]
Please investigate this billing error and correct my account. I have enclosed copies of [receipts, order records, tracking information, correspondence, refund confirmation, or other evidence].
Please send me written confirmation of the result. If you determine that no billing error occurred, please explain why and provide copies of the documents supporting that decision.
Sincerely,
[Name]
[Mailing address]
[Account identifier requested by the issuer]
Use a delivery method that lets you show when the issuer received the letter. Keep the letter, attachments, delivery record, and response together.
If the issuer denies the dispute
Start with the issuer's written explanation. It may show that:
- The wrong transaction or amount was reviewed
- The reason for the dispute was misunderstood
- A cancellation, delivery record, or refund was overlooked
- A needed document was missing
- The issuer decided that the facts don't fit the billing-error definition
If the explanation doesn't include the supporting documents, ask for them. Then reply briefly to the stated reason for the denial and add only relevant new evidence.
Some issuers offer reconsideration or an appeal. Follow the deadline in the issuer's notice. If the issuer missed the 30-day acknowledgment or 90-day resolution timeline, point out the dates and ask how it will address the missed deadline. Keep the case number and a record of each call, letter, upload, and response.
For a large or complicated claim, a qualified consumer-law attorney or local legal-aid organization may be able to assess the specific facts. General information can't replace advice about an individual dispute.
Mistakes that can weaken a dispute
- Waiting for a merchant response until the 60-day notice period is over
- Calling the issuer but never sending the written explanation
- Sending the notice to the payment address rather than the billing-inquiries address
- Disputing the whole balance when only one charge is at issue
- Calling something "fraud" without explaining what happened
- Leaving out the statement date, transaction amount, or merchant name
- Sending unrelated screenshots instead of records connected to the charge
- Failing to pay the undisputed part of the bill
- Treating a card-network rule or an internet deadline as a rule for every issuer and transaction
Questions consumers often ask
Can I dispute a credit card charge without contacting the merchant?
Yes. You can notify the issuer directly, and you shouldn't delay the written notice while waiting for the merchant. Contacting the merchant may still produce a faster refund and useful records.
Does a no-refund policy prevent a chargeback?
Not automatically. It does mean a change of mind may not be enough. Explain whether the charge was unauthorized, incorrect, not delivered, or otherwise connected to a billing error. The issuer will decide after reviewing the facts and documents.
Can I use the 60-day rule for a debit card purchase?
Don't assume so. The rule discussed here applies to U.S. credit-card billing errors. Debit, prepaid, bank-transfer, and peer-to-peer transactions have different procedures, so contact the provider shown on that account.
How long does a credit card dispute take?
The issuer generally has 30 days to acknowledge a written notice unless it resolves the issue sooner. It generally must complete the investigation within two billing cycles and no later than 90 days after receiving the notice.
What if the merchant promised a refund but never posted it?
Include the written promise, the expected refund date and amount, and statements showing that the credit is missing. A failure to post a credit can itself be relevant to a billing-error notice.
Do online chargeback statistics guarantee success?
No. Win-rate claims, automated-tool results, and broad statements about 120-day deadlines don't guarantee a consumer outcome. The payment type, issuer's instructions, timing, and evidence for your transaction control what happens next.
If the 60-day period is close to expiring, send the written notice now to the billing-inquiries address, keep proof of delivery, and pay the undisputed balance on time.
