If you've spotted an unauthorized charge on your credit card, a fraudulent debit from your bank account, or a scam via Zelle or Venmo, act fast. This comprehensive 2026 guide draws from FTC and CFPB rules to provide checklists, timelines, sample letters, and processes for banks, cards, PayPal, Venmo, Zelle, ACH transfers, and wires.

2. Freeze or cancel affected accounts/cards.
3. Gather evidence (statements, screenshots, timelines).
4. File a police report and FTC complaint at ReportFraud.ftc.gov.
5. Monitor for resolution (10 business days prelim investigation, up to 90 days full).

Follow the detailed checklists below to recover your money.

Quick Start Checklist: First Steps for Any Unauthorized Transaction Complaint

When fraud strikes--whether a bank withdrawal, credit card charge, or P2P scam--speed is key. FTC and CFPB rules mandate banks investigate within 10 business days and resolve in 45-90 days. Here's your instant 7-step checklist:

• Step 1: Secure your accounts – Call your bank's fraud hotline (on the back of your card or app) to report the unauthorized transaction. Request a freeze, card replacement, or account lock. Do this immediately to limit liability.
• Step 2: Notify in writing within 60 days – Under EFTA/FCBA, you have 60 days from the statement date showing the charge. Email or mail a dispute letter (sample below).
• Step 3: Document everything – Screenshot transactions, note dates/amounts, save emails. Banks must acknowledge within 30 days (credit) or investigate in 10 business days (debit).
• Step 4: File external reports – Report to FTC at ReportFraud.ftc.gov and local police for an official report. This strengthens your claim.
• Step 5: Change passwords and enable alerts – Update logins for banking apps, email, and P2P services.
• Step 6: Monitor statements – Provisional credit often comes in 10 days (debit) or 2 billing cycles (credit).
• Step 7: Escalate if needed – File with CFPB if no resolution in timelines.

Missing the 60-day window? You may owe the full amount post-statement (CFPB).
