Unauthorized Transaction Dispute Letter Template: Your 60-Day Guide (2026 Update)

Spotting an unauthorized charge on your credit or debit card statement requires quick action. The Federal Trade Commission provides an official sample dispute letter template to notify your card issuer effectively. Under FTC guidelines, you must report the issue within 60 days from when the first statement showing the charge was sent to you. This timeline protects your right to a correction, including credits for the disputed amount and any related fees.

This guide delivers the exact FTC template, a full workflow for disputing charges, and options like fraud reporting forms. Consumers can copy, customize, and send the letter to resolve fraudulent transactions without losing money. For escalations, chargeback responses handle cases like MasterCard reason code 4863 for unrecognized charges.

The 60-Day Rule for Disputing Unauthorized Charges

Federal law sets a firm deadline for disputing unauthorized charges on credit or debit cards. You need to tell your card company about the error within 60 calendar days of when the first statement with the disputed charge was sent. Missing this window risks permanent liability for the charge.

The FTC outlines this rule clearly: act promptly upon reviewing your statement to preserve your rights. Card issuers must investigate and respond, often provisionally crediting your account during review. This process applies uniformly to unauthorized transactions, ensuring consumers face no undue burden from fraud they did not authorize.

Delays beyond 60 days can forfeit protections, so check statements regularly and document everything. Early reporting triggers the issuer's obligation to resolve the matter. The 60-day metric stems directly from FTC guidance on disputing unauthorized credit or debit card charges, emphasizing the need to notify within 60 calendar days from the statement transmittal date.

Step-by-Step Workflow to Report and Dispute Unauthorized Transactions

Follow this FTC-based process to report and dispute unauthorized charges systematically. This workflow aligns with the requirement to notify your card issuer within 60 days of the statement date.

1. Review your statement immediately: Identify the suspicious charge, noting the amount, date, merchant, and any details. Compare against your records to confirm it is unauthorized. Regular checks help you spot issues early within the 60-day window.

2. Contact your card issuer by phone: Call the number on the back of your card or statement right away. Report the fraud verbally and request a provisional credit. Get a case or reference number. This initial contact starts the process per FTC guidelines.

3. Send the written dispute: Within the 60-day window, mail the FTC sample dispute letter via certified mail with return receipt. Include supporting documents like statements. The written letter provides formal documentation of your claim.

4. Monitor your account: Watch for provisional credits, which issuers often apply during investigation. The process typically takes up to 45 days for credit cards or two billing cycles for debit. Provisional credits protect you while the review occurs.

5. Follow up: If no response within 30 days, call again. Keep records of all communications, including dates, names, and reference numbers.

For banks, credit unions, or fintech, consider the Jotform Fraudulent Transaction Review Request Form as an optional digital alternative. It captures details for fraud teams in ecommerce or accounting. Always pair it with the written letter for full protection. This step-by-step approach ensures comprehensive handling of unauthorized transactions from detection to resolution.

When to Use Chargeback Responses for Unauthorized Disputes

Start with your issuer's dispute process for unauthorized charges, as it aligns with the 60-day FTC rule. Escalate to chargebacks if the issuer denies your claim or the merchant disputes it further.

Unauthorized transactions represent 30% of all chargeback reason codes (Chargeflow). Examples include MasterCard 4863 for "Cardholder Does Not Recognize - Potential Fraud." Use chargeback response templates to provide evidence like transaction logs or affidavits when responding to merchant challenges.

The Chargeflow blog details these templates and codes. Opt for issuer disputes first, as they are simpler and faster. Reserve chargebacks for unresolved cases, ensuring you document everything to strengthen your position. This escalation path builds on the initial FTC dispute process for unauthorized transactions.
