Your deadline depends on how you paid. For a U.S. credit-card billing error, the issuer must receive a written notice within 60 days after the first statement showing the error. An unauthorized debit or other electronic-transfer error follows Regulation E instead; report it promptly, and generally no later than 60 days after the statement where it first appears.
An issuer's chargeback review is not a merchant refund. The issuer investigates, may give provisional credit, and can ask the merchant's bank for a response. The outcome depends on the dispute reason, the records, and the payment rail.
These rules concern U.S. consumer accounts. Other countries may use different procedures. This is general information, not legal advice.
What actually controls your dispute
Start with the payment rail. The label "chargeback" doesn't tell you which rule applies.
Credit cards, debit cards, and payment apps can involve different forms, protections, and deadlines.
| Payment method | Main rule or process | Common issues | Deadline to protect yourself |
|---|---|---|---|
| Credit card | FCBA billing-error process under Regulation Z | Unauthorized charges, wrong amounts, missing credits, or goods and services not accepted or not delivered as agreed | Written notice within 60 days after the first statement showing the error |
| Debit card or other electronic fund transfer | Regulation E error-resolution process | Unauthorized electronic transfers and certain account errors | Notice generally no later than 60 days after the statement showing the error; report sooner |
| Visa or Mastercard network dispute | Network and issuer or acquirer procedures | Network-defined fraud, duplicate, non-receipt, and similar claims | Follow the issuer's notice; the category and transaction facts matter |
| Bank transfer or payment app | The provider agreement and payment rail rules | Varies by service | Contact the provider promptly; credit-card rules don't automatically apply |
Federal rights and network procedures aren't interchangeable. An issuer may ask for a different form or give you a shorter response window, so read its notice carefully.
Credit-card chargeback rights under the FCBA
Credit-card billing errors use the Fair Credit Billing Act process carried out through Regulation Z. An unauthorized charge, wrong amount, missing credit, or goods or services not accepted or not delivered as agreed may qualify. The CFPB's billing-error regulation sets out the process.
Your notice has to reach the issuer within 60 days after the first statement showing the error. Send it to the billing-inquiry or billing-error address printed on the statement. The payment address may be different.
Include your name, account number, transaction date, merchant, disputed amount, explanation, and the correction you want. Keep a copy. Save delivery proof or the issuer's online confirmation.
Calling can help lock the card or start a case. It doesn't replace written notice for the full federal billing-error process.
The issuer generally must acknowledge a written notice within 30 days unless it resolves the problem sooner. It then must resolve the dispute within two billing cycles, and no later than 90 days. During the investigation, the FTC says you don't have to pay the disputed amount or related finance and other charges. Keep paying the undisputed part of the bill.
Debit-card and electronic-transfer rights
A debit-card dispute isn't automatically an FCBA matter. Regulation E governs electronic fund transfers, including unauthorized transfers and certain account errors.
Under the CFPB's Regulation E procedure, the institution generally must receive notice no later than 60 days after it sends the statement where the alleged error first appears. Tell the institution sooner. Waiting can affect the protections available to you.
After notice, the institution generally investigates promptly and determines whether an error occurred within 10 business days. In some situations, the rule permits a longer investigation when it provides provisional credit. The eCFR text of Regulation E contains the procedural details.
Oral notice may be enough at first. If the bank asks for written confirmation, send it within 10 business days.
An authorized debit-card purchase that never arrives may not fit the same federal error category as an unauthorized withdrawal. Ask the bank whether a network dispute is available, and keep the order records and seller messages.
Chargeback deadlines are not all the same
Turns out, the familiar "120 days for the consumer and 20 days for the merchant" formula doesn't cover every dispute. Use the timing that matches your payment rail and case stage.
| Situation | Deadline or timing to use |
|---|---|
| Credit-card billing error | Make sure the issuer receives written notice within 60 days after the first statement showing the error |
| Debit-card or electronic-transfer error | Notice generally received within 60 days after the statement showing the error |
| Credit-card issuer acknowledgment | Generally within 30 days, unless the issuer resolves the matter sooner |
| Credit-card investigation | Within two billing cycles, but no more than 90 days |
| Network chargeback | Follow the date and procedure in the issuer's notice; it varies by network, reason code, transaction type, and stage |
| Consumer appeal | Follow the date and instructions in the issuer's decision; there is no universal 45-day appeal rule |
Visa and Mastercard rules sit alongside federal law. They don't replace it. For a network case, follow the date and instructions in the issuer's notice.
How to file a dispute without losing your rights
Do the bank-notice step before chasing the merchant. Merchant contact can help, but it shouldn't consume the deadline.
- Identify the payment rail. Check whether the transaction used a credit card, debit card, electronic transfer, bank account, or payment app.
- Secure an unauthorized account. Lock the card when possible, notify the issuer, and change relevant account credentials.
- Contact the merchant when useful. For non-delivery, cancellation, or a missing refund, ask for a written resolution. Don't let that conversation run past the bank's notice deadline.
- Use the accurate dispute reason. Don't describe an authorized purchase as fraud just because the product was late or defective. State what actually happened.
- Send the formal notice. Use the credit-card billing-error address or the debit bank's fraud and error channel. If the bank requests written confirmation, provide it promptly.
- Attach focused evidence. Lead with the statement, receipt, order record, and document that proves the problem.
- Track the case. Save the case number, provisional-credit notice, follow-up requests, and final decision.
- Appeal when appropriate. Ask why the dispute was rejected, what evidence was relied on, and how to request reconsideration before the listed deadline.
Tell the issuer if the merchant later issues a refund. A refund and a chargeback shouldn't produce a double recovery.
Evidence that matches the dispute reason
Match the evidence to the reason. A receipt proves that a transaction occurred; it doesn't prove every part of your claim.
| Dispute reason | Useful records | What they help establish |
|---|---|---|
| Unauthorized transaction | Statement, fraud alert, card or account information, account-security records, and relevant travel or possession details | Why you believe you did not authorize the transaction |
| Goods or services not received | Order confirmation, promised delivery date, tracking history, cancellation request, and seller messages | What was promised and what failed to arrive |
| Wrong amount or duplicate charge | Receipt, invoice, statement, and records of any other payment | The amount that should have been charged |
| Credit or refund missing | Merchant's refund confirmation, return tracking, cancellation record, and statement | That the merchant promised or processed a credit that did not appear |
| Goods or services not as agreed | Listing, contract, service description, photographs, and communications | How the delivered item or service differed from the agreement |
To be honest, a tidy timeline often helps more than unrelated screenshots. Keep the original files too. Screenshots help, sure, but the issuer may need the full email, statement, or tracking page.
Write down dates while they're fresh. Refund promises can make the sequence messy.
When a merchant challenges the chargeback
Merchants can challenge chargebacks. Usually, they do it through representment, using their acquirer or payment processor and the applicable network procedure.
| Merchant record | Question it may answer |
|---|---|
| Delivery, pickup, or service record | Was the order delivered or the service provided? |
| Transaction and authorization data | How was the payment entered and processed? |
| Refund, cancellation, or return records | Did the merchant already issue a credit or follow its stated terms? |
| Customer communications | Did the parties agree to a later delivery, replacement, or resolution? |
Merchant response deadlines belong to the merchant's bank and the network. They are separate from your deadline to notify the issuer. Generic online charts aren't reliable for a specific case.
Representment isn't a court judgment. If the issuer sends you the merchant's response and invites a reply, answer through the issuer's channel. Point to the record that is wrong, incomplete, or unrelated to your transaction.
If the issuer rejects the dispute
Provisional credit can be taken back. It isn't necessarily final.
Ask for the decision in writing. Request the reason for the rejection, the evidence considered, and the deadline or method for reconsideration. A useful appeal responds to the stated gap instead of repeating the original complaint.
Thing is, a delivery record may show that something arrived without proving the correct item did. An authorization record doesn't prove that the amount was correct. Use dates and documents to show the difference.
If the issuer failed to process a timely notice, acknowledge it, investigate it, or follow the applicable response rules, keep your complete timeline and consider a complaint to the CFPB. A regulatory complaint can address a process problem, but it doesn't guarantee a refund.
For a large loss, identity-theft issue, or complicated contract dispute, consider advice from a qualified consumer-law professional.
Common questions
Is a chargeback guaranteed if I have a receipt?
No. A receipt confirms the transaction. The issuer still weighs the stated reason, the merchant's response, and the evidence from both sides.
Do Visa and Mastercard always give consumers 120 days?
No. Network time limits vary by reason code, transaction type, region, and dispute stage. Protect the separate 60-day written-notice deadline for a U.S. credit-card billing error.
Can I dispute a debit purchase that never arrived?
Possibly. Don't assume Regulation E gives the same protection as the credit-card billing-error process. Ask the bank whether a network dispute applies and provide the order and delivery records.
Does a merchant have the right to respond?
Usually, yes. Representment gives the merchant a way to submit records through its payment processor. Respond if the issuer gives you that opportunity.
Pull up the statement first. Mark the date the charge appeared and whether it was credit or debit. Send the notice through the correct channel before the applicable deadline.
