Quick answer

Start with the bank or credit union that issued the debit card. Visa and Mastercard don't normally take a consumer's claim directly.

What you report matters:

• A charge or withdrawal you didn't make: report possible unauthorized activity right away and secure the card.
• A lost or stolen card: lock it if you can, then notify the issuer promptly.
• A duplicate charge or wrong amount: report an error, even if you made the original purchase.
• A purchase that never arrived, was defective, or was charged after cancellation: seek a merchant refund first, then ask the issuer about its debit-card dispute process.

For U.S. personal checking and savings accounts, Regulation E can set both error-resolution rules and liability limits. It generally gives you 60 days from the statement date to report a listed error. A separate two-business-day rule can matter when you learn that a debit card or other access device was lost or stolen.

This information is for U.S. consumer accounts used mainly for personal, family, or household purposes. Business accounts, credit cards, and some prepaid or payment-app transactions can follow different rules.

Match the problem to the right route

A debit-card dispute isn't one single process. The facts determine whether you are reporting a Regulation E error or asking the issuer to pursue a card-network dispute.

Don't call an authorized purchase "fraud" simply because the merchant has been difficult. Tell the bank what happened, when it happened, and what you did to resolve it.

When Regulation E applies

Regulation E error-resolution procedures generally apply to certain electronic fund transfer errors on consumer accounts, including:

• An electronic transfer you did not authorize
• A transfer for an incorrect amount
• A transfer posted more than once
• An electronic transfer omitted from a periodic statement
• Certain bookkeeping or statement errors involving an electronic transfer

A wrong amount or duplicate debit may be a covered error even though you authorized the original purchase.

A complaint about product quality, a late delivery, or a merchant refusing a refund is different. Regulation E does not automatically require the bank to refund an authorized purchase because the merchant performed poorly. The issuer may still have a debit-card dispute or chargeback process through the card network, but its eligibility rules, evidence requirements, and deadlines can differ.

Credit-card billing disputes are governed by different rules. The Fair Credit Billing Act process described in the FTC's credit-card dispute guidance should not be treated as the procedure for a debit-card transaction.

Deadlines that can affect your protection

Report statement errors within 60 days

For most listed errors, the financial institution must receive your notice no later than 60 days after it sent the first periodic statement showing the problem.

You can start with a phone call. The bank may require written confirmation after an oral report, however. Ask where to send it and submit it through the bank's designated secure message system, upload tool, or error-notice address. If the institution properly requests confirmation and does not receive it within 10 business days, it may not have to provide provisional credit during an extended investigation.

Don't wait until day 60. A delay can make it harder to investigate and may affect responsibility for later unauthorized transfers. Regulation E also requires a reasonable extension when extenuating circumstances prevented timely notice, but that is not a reason to postpone reporting.

Report a lost or stolen debit card within two business days

The two-business-day rule is separate from the 60-day statement deadline.

If you learn that your debit card or another access device was lost or stolen, notify the issuer within two business days. Under the federal baseline, your liability for unauthorized transfers before notice is generally limited to the lesser of $50 or the amount transferred before you reported the loss.

Waiting longer can increase potential liability. In some circumstances, the federal limit can reach $500. If unauthorized transfers appear on a statement and you do not report them within 60 days, you may also be responsible for later transfers the institution could have prevented.

These rules set federal limits; they do not promise that every claim will be approved. Your account agreement or card network may provide stronger protections. The FTC's lost or stolen card guidance also advises consumers to report unfamiliar charges and withdrawals immediately.

Your institution's disclosures should explain what it counts as a business day. Don't assume a weekend or holiday is included.

How to file the dispute

1. Secure the card and account when fraud is possible

If the card is missing, stolen, or appears compromised, lock it through the banking app if that feature is available. Treat the lock as a temporary safeguard, not as notice to the bank.

Call the number on the card, use the official app, or use the number on your statement. Ask whether the card should be canceled and replaced and whether you should change the PIN.

If someone may have accessed online banking, change the password and turn on multifactor authentication. Do not share a password, PIN, or one-time verification code with an unexpected caller, text, or email.

2. Check the transaction before labeling it fraud

Look at the merchant descriptor, date, amount, location, and status. A pending authorization is not always the final amount. A restaurant tip adjustment, temporary hold, digital-wallet purchase, recurring subscription, joint account holder, or merchant's legal business name may explain an unfamiliar entry.

Save a screenshot or download the statement if the transaction still appears wrong. For an unrecognized charge or a missing card, do not delay the fraud report while you search for every receipt.

3. Give the issuer a clear report

State the facts without guessing. Identify the account, transaction date, amount, merchant description, and the reason for the dispute.

For example, explain one of these points:

• You did not authorize the electronic transfer.
• You authorized a purchase for one amount, but a different amount posted.
• The same transaction was debited twice.
• You canceled a recurring service on a stated date, and the merchant charged you afterward.
• You authorized the purchase, but the goods or services were not provided.

Ask for:

• The claim or case number
• The correct method for sending documents or written confirmation
• The deadline for additional evidence
• Whether the item must post before the bank will open the case
• Whether provisional credit could apply
• The date of the next update

Write down the representative's name, the date and time, and what you were told.

4. Confirm the error in writing

A written notice creates a cleaner record, especially when the claim concerns a statement-listed Regulation E error. Use the bank's designated channel rather than a general customer-service inbox.

Include:

• Your name and contact details
• The last four digits of the affected account or card
• The transaction date, amount, merchant name, and statement description
• The reference number, if available
• A short explanation of the error
• The amount you believe should be corrected
• A list of documents attached
• A request for written results

Use copies, not irreplaceable originals. Do not send a PIN, password, or one-time code. If you are not using the bank's secure system, avoid including more account information than necessary.

5. Send evidence that addresses the actual issue

The most useful documents depend on the claim:

• Statement or transaction screenshots
• Receipts, invoices, or order confirmations
• Merchant emails, chat records, or cancellation confirmations
• Proof of a duplicate debit or changed amount
• Delivery information or proof that an order was not received
• A brief timeline showing when you discovered and reported the problem
• A police or identity-theft report, if you already made one

A police report may help document suspected fraud, but you do not need to wait for one before notifying the bank.

6. Use the merchant route for an authorized purchase problem

For non-delivery, defective goods, or a subscription issue, contact the merchant and request a written refund decision. Keep the cancellation notice, return tracking, promised refund date, and any merchant reference number.

If the merchant will not resolve it, ask the issuer whether its debit-card dispute process covers the transaction. The issuer may use Visa, Mastercard, or another card network to pursue the claim with the merchant's bank. That process is not a guaranteed refund, and the deadline may be shorter than the 60-day Regulation E notice period.

Tell the bank if the merchant later refunds you. That helps prevent an accidental double credit.

Investigation timelines and provisional credit

For a covered Regulation E error, the institution generally must investigate promptly and decide whether an error occurred within 10 business days after receiving your notice.

A new account can have a longer initial period of up to 20 business days. If the institution needs more time, it can generally extend the investigation only if it provides provisional credit within the applicable period and gives you use of the credited funds while it investigates. The ordinary extended period is up to 45 calendar days.

The investigation can run up to 90 calendar days in specified situations, including certain new-account matters, point-of-sale debit-card transactions, and transfers initiated outside the United States.

After the investigation ends:

• If the institution finds an error, it generally must correct the account within one business day.
• It generally must report the results within three business days.
• If it finds no error, it must send a written explanation and tell you that you can request the documents used in reaching that result.

Provisional credit is temporary, not a final decision. If the bank later concludes that no error occurred, it may reverse the credit. Read every notice, request the supporting documents, and compare the decision with your records.

These timing rules apply to covered Regulation E errors. A merchant dispute or network chargeback may take a different path and schedule.

Debit card error notice template

Follow your bank's form or instructions if it provides one. This format can help you organize a written notice.

[Your name]

For an authorized purchase that was not delivered or was otherwise unsatisfactory, use a subject such as "Debit-card purchase dispute" and describe the merchant problem accurately. Do not state that the transaction was unauthorized if you approved it.

If the bank denies the claim

Ask for the written explanation and the documents supporting the decision. Then check the bank's account of the transaction against your own records: the date, amount, merchant description, authorization details, cancellation date, and the day you first reported the issue.

If the decision appears wrong, send a short reconsideration request. A focused timeline and the missing evidence are more useful than resending an unorganized file. For an authorized purchase dispute, also ask whether a separate card-network claim is available.

You can file a complaint through the CFPB complaint portal if you believe the institution did not follow the required process. Your bank's disclosures should identify its regulator. For credit unions, the NCUA's Regulation E information describes applicable federal protections.

A regulator complaint does not guarantee a refund or replace the bank's investigation. Keep the case number, notices, evidence, and copies of every submission.

Common questions

Can I dispute a debit card charge online?

Usually. Many banking apps let you select a posted transaction and choose a fraud or dispute option. Save the confirmation screen and case number. If there is no option, call the number on the card and ask where to submit an error notice or debit-card dispute.

Can I dispute a pending debit card charge?

You can report suspected fraud while a charge is pending and ask the bank to secure the card. Some institutions wait for the charge to post before opening a formal dispute. A pending hold may also change or disappear without becoming a final debit.

Do Visa and Mastercard handle the dispute directly?

Usually not. The issuer starts the consumer claim and may use the card network's system with the merchant's bank. The card logo does not replace the issuer's Regulation E duties or its own dispute deadlines.

Is a debit-card dispute the same as a credit-card dispute?

No. Debit-card transactions generally draw from a deposit account and may be governed by Regulation E. Credit-card billing disputes follow different procedures under the Fair Credit Billing Act.

What if provisional credit is reversed?

Read the reversal notice, request the documents from the investigation, and compare them with your evidence. If the facts are wrong or material evidence was missed, send a concise rebuttal and ask for reconsideration.

If the transaction is already on a statement, note the statement date, save the transaction details, and report the issue through the issuer's official channel now. If the card is missing or the charge is unrecognized, lock the card first.
