Credit card charge disputes start with paperwork. A phone call rarely locks in your rights. If you want the Fair Credit Billing Act and Regulation Z to apply, written notice has to reach your issuer.
Most people skip that step. They call, get a promise, and then the deadline passes. This template covers unauthorized charges, wrong amounts, mystery charges, and payments that were never credited. It's for U.S. credit cards. Debit cards follow a different rulebook.
What Counts as a Credit Card Billing Error
Not every bad purchase counts. A late package or a dirty hotel room is a merchant dispute. The FCBA process isn't built for quality complaints.
The law covers specific errors. Those include an unauthorized charge, a charge the statement doesn't identify properly, a wrong amount, a payment that wasn't credited, and math or accounting mistakes. You can read the rule at 12 CFR 1026.13. The FTC explains the same process in plain English at Using Credit Cards and Disputing Charges.
Thing is, the category matters more than people think. Dispute an authorized, correctly billed charge as a billing error and the issuer will likely reject it. You may still have a claim against the merchant. That claim runs on a separate track.

Copy the letter and fill in every bracket. Mail it to the billing inquiries address printed on your statement, not the general customer service address. Keep a copy. Send it by certified mail with return receipt.

Re: Billing error dispute - Account ending [last 4 digits]
Transaction date: [date]
Amount: $[amount]
Merchant: [merchant name]
Dear Sir or Madam,
I am writing to dispute a billing error under the Fair Credit Billing Act, 15 U.S.C. 1666, and Regulation Z, 12 CFR 1026.13.
The charge I dispute is:
Date: [date]
Amount: $[amount]
Merchant: [merchant name]
Why it is wrong: [example: I did not authorize this charge. I reported my card lost on [date].]
I am sending this notice within 60 days after the first statement that showed the error. Please investigate this billing error. If you find that an error occurred, correct my account within the time required by Regulation Z. Please acknowledge this dispute in writing within 30 days if you have not resolved it. If the law requires a provisional credit during your investigation, please apply it.
Enclosed are copies of: [list evidence, such as statement pages, receipts, emails, cancellation confirmation, police report].
Please send all correspondence to the address at the top of this letter.
Sincerely,
[Your Name]
Account number: [account number]For an overcharge, write the amount you were charged and the amount you believe is correct. If you don't recognize the charge, say so and ask for a copy of the transaction record. When a stolen card is behind the charge, include the police report number and the date you reported the loss. Visa and Mastercard zero liability policies may add protection on top of that, but your legal rights come from federal law and your card agreement. The FTC has separate guidance on lost or stolen cards.
Deadlines and What the Issuer Must Do
Timing is where disputes live or die. The 60-day clock starts on the statement date, not the purchase date. Turns out, that detail catches people off guard.
| Stage | Timing | What it means |
|---|---|---|
| Written notice | Within 60 days after the first statement with the error | This is the key deadline. Miss it and you may lose FCBA billing error protections for that charge. |
| Issuer acknowledgment | Within 30 days of receiving your notice | Unless the issuer resolves the issue in that time, it must acknowledge your dispute in writing. |
| Resolution | Within two billing cycles, and no more than 90 days | The issuer must finish its investigation and correct the account if it finds an error. |
| Provisional credit | If required during investigation | If the issuer doesn't resolve the dispute quickly, it may have to credit the disputed amount while it investigates. |
Those timelines come from the CFPB's Regulation Z billing error rule and the eCFR text of 12 CFR 1026.13. If you move, put your new address in writing to the issuer. The FTC notes the issuer must have that change at least 20 days before the billing period ends.
Evidence That Helps Your Dispute
A letter alone can work. Documents make the dispute faster to verify. Send copies, never originals. The statement page showing the disputed charge is usually the most useful attachment. Add whatever explains why the charge is wrong: a receipt, an order confirmation, an email from the merchant, a cancellation notice, a repair estimate, or a police report if the card was stolen.
- [ ] Statement page with the disputed charge
- [ ] Receipt, invoice, or order confirmation
- [ ] Emails or chat logs with the merchant
- [ ] Police report or identity theft report, if relevant
- [ ] A copy of your letter and certified mail receipt
If you don't recognize the merchant, ask the issuer for the transaction record. If you are disputing an overcharge, include the receipt and the statement page together.
How to Send It and Follow Up
Certified mail with return receipt gives you proof of delivery. Keep a copy of everything you send. If you get no response after 30 days, call and ask for the status. If the issuer asks you to follow up in writing, do it inside whatever window it gives you. Keep paying the undisputed part of your bill on time. Withholding the whole balance over one disputed charge invites late fees and credit reporting problems.
If the issuer denies the dispute, ask for the explanation in writing. New evidence can support an appeal. You can also file a complaint with the CFPB or your state attorney general. The CFPB's unauthorized transaction guidance covers bank accounts and debit cards, which follow different rules. For credit card billing errors, stay with the FCBA process described above.
Common Mistakes That Weaken a Dispute
Waiting too long is the biggest one. That 60-day window runs from the statement, not from the day you noticed the charge.
Sending an email to customer service and assuming it counts as written notice is another common slip. It might count. Certified mail gives you a cleaner record either way.
Don't send originals. Don't bury the key facts in a long story. Put the date, amount, merchant, and reason in the first few lines. If you have several disputed charges, list them clearly or send separate letters for each one. Don't ignore a request for more information. One missing document can flip a strong dispute into a denial.
To be honest, the letter doesn't need to read like a legal brief. It needs to be clear, dated, and tied to evidence the issuer can check.
FAQ
Can I use this template for a debit card charge? No. Debit card and bank account disputes fall under the Electronic Fund Transfer Act, with different timing rules. Use this template for credit card billing errors only.
Does the letter have to be notarized? No. A signed letter with your account information and a clear explanation is enough. Keep it factual.
Can I dispute a charge because I didn't like the product? Usually no. The FCBA billing error process covers unauthorized charges, wrong amounts, missing credits, and similar errors. A quality complaint normally belongs with the merchant.
Fill out the template, attach the statement page, and mail it to the billing inquiries address. Keep the certified mail receipt with your copy. That paper trail is what moves the dispute.
