A debit card charge you didn't authorize comes straight out of checking. Credit cards work differently.

Can a letter actually get the money back? A written notice can start Regulation E's error process and prove what you told the bank, and when you told them.

Call or tap the transaction in your app today if you can. Mail or upload a letter the same week. Thing is, a lot of free FCBA debit templates point to the wrong law.

Regulation E, not the Fair Credit Billing Act

Unauthorized debit card charges, ATM withdrawals, and similar electronic transfers from a U.S. consumer account are covered by the Electronic Fund Transfer Act, implemented as Regulation E.

The Fair Credit Billing Act is a credit billing statute. It does not run a normal debit card transfer. Pasting 15 U.S.C. 1666 into a checking-account letter will not change that.

People mix this up constantly because the plastic looks the same, the monthly statement looks similar, and countless templates paste Fair Credit Billing Act language into a debit dispute as if those two rules were interchangeable, which they are not, and the employee who reads your letter is usually hunting for the date, the dollar amount, and why you say the transfer was unauthorized.

The CFPB says you must notify your bank no later than 60 days after it sent the statement that first showed the unauthorized transaction. Wait longer and you could owe later unauthorized transfers that posted before you spoke up.

You don't need a police report before you notify the bank. File one later if you want. Don't sit on the 60-day clock.

Deadlines that actually bind the bank

These time frames come from 12 CFR 1005.11, not from a bank slogan.

Your deposit agreement might give you extra time or easier credit. It cannot cut back the error-resolution process Regulation E sets for covered consumer accounts.

Lost-card liability is a different clock. If the physical card or PIN was stolen, telling the bank within two business days of learning about the loss can cap that slice of liability. The 60-day statement window still applies to unauthorized transfers that show up later.

How to file so the date is clear

Skip the perfect packet. Start the claim, then write.

1. Lock or replace the card if the number may be out in the wild.
2. Use the in-app dispute option on the charge if your bank has one. Large U.S. banks, including Bank of America, Chase, and Wells Fargo, usually let you start that from the transaction itself. Save the confirmation.
3. Call the number on the card. Write the date, time, and claim number.
4. Send this letter to the address on your statement, or the dispute address the agent gives you.
5. Mail it certified with return receipt if you want proof of the date. Keep a copy either way.
6. If they asked you to confirm a phone report in writing, get that letter in within 10 business days.

Turns out the app filing and the letter are not rivals. The app is quicker. The letter is what you hold up if someone later says the bank never received the details.

What to attach

Keep the letter short. Attach the statement page with the charge marked, plus any merchant emails or cancellation screens, and the date and claim number from your phone call.

Add a police report only if you already have one. Don't photocopy the full front of the card. Last four digits are enough.

What happens after you send it

Watch the account. Provisional credit is a maybe, and it can be pulled back.

The bank generally has 10 business days to decide whether an error occurred. If it needs more time, it often must credit you temporarily while it investigates. Many files then run up to 45 days. Some point-of-sale and foreign transfers can take longer under that same section.

If they refuse the claim, read the explanation. Ask for the materials they used. If they reverse a provisional credit, they may have to honor certain checks and scheduled payments for a few days so you can adjust.

To be honest, plenty of denials happen because you typed yes on a payment, even if a scammer talked you into it. Regulation E's unauthorized-transfer idea is tighter than "I want this reversed." P2P and bank-app sends you confirmed are the usual sticky cases. Still report them. Just don't treat the debit-card error rule as a guaranteed unwind.

If the file stalls or the denial looks off, submit a complaint to the Consumer Financial Protection Bureau. Bring the claim number, dates, and your copies.

Open the statement that shows the charge, fill in the template, and get the notice to the bank while you're still inside that 60-day window.
