How to Complete and Submit a Credit Card Chargeback Dispute Form

A credit card chargeback dispute form is the written notice you send your card issuer asking it to reverse a charge, and the Fair Credit Billing Act gives you 60 days from the date the first statement containing the error was mailed or transmitted to get that notice in.¹ The form itself is short. What determines whether it works is where you send it, what you attach, and whether you describe the problem in terms the law recognizes as a billing error.

Charges You Can Dispute

Federal law treats “billing error” broadly. The categories that qualify include:

Unauthorized charges, including fraudulent use of your card number.
A charge posted for a different amount than you agreed to pay.
Goods or services that never arrived, or that you refused on delivery.
Payments or merchant credits that don’t appear on your statement.
Math or accounting mistakes on the statement itself.
A statement the issuer failed to mail to your correct address, provided you gave that address at least 20 days before the billing cycle ended.
Charges you need clarified because you don’t recognize them and want documentary proof of what they were.

That last category is wider than it reads. An unfamiliar merchant name on your statement is, by itself, grounds to file a dispute asking for evidence of the transaction.²

For unauthorized use specifically, your personal liability is capped at $50 by statute, and most major issuers waive even that under zero-liability policies.³ Debit cards work under a different rule with much weaker protection, so the process below applies to credit cards only.

The 60-Day Deadline

Your written dispute must reach the issuer within 60 calendar days of the date the first statement containing the error was sent.¹ The clock runs from the send date, not from when you opened the statement. Paperless billing doesn’t pause it. If you don’t check your account for two months, the window may already be closed.

Miss the deadline and the issuer no longer has to investigate under federal law. You can still try the bank’s internal process or the card network’s chargeback system, but you lose the protections that stop the issuer from collecting the disputed amount, charging interest on it, or reporting it as delinquent while the matter is open. Check your statements every cycle.

What the Form Has to Say

Most issuers publish their own dispute form on their website, in their mobile app, or on the back of paper statements. Whether you use that form or write a letter, the statute requires three things: your name and account number, a statement that you believe the bill contains an error along with the dollar amount, and the reasons you believe it’s wrong.¹ Add these specifics so the investigator isn’t guessing:

The transaction date exactly as it appears on your statement, not the date you placed the order.
The merchant name copied verbatim from the billing record. Statement descriptors often look nothing like the storefront you remember.
The exact dollar amount down to the cent. If you’re contesting only part of a charge, give both the total and the portion in dispute.
The reason category. If the form offers a dropdown, pick the one that matches. Card networks route disputes by internal reason codes — Visa uses 13.1 for merchandise not received and Mastercard uses 4855 for the same thing — and the right category gets your case to the right queue.⁴
A short factual narrative. Dates, actions, outcomes. Something like: “Ordered Nov 3, seller promised delivery by Nov 15, item never arrived, contacted seller Nov 20, no response.”

If your issuer doesn’t offer a form or you’d rather write from scratch, the FTC publishes a sample dispute letter that covers every required element.⁵

What to Attach

The form opens the investigation. The evidence you attach often decides it. Build a timeline the bank can verify without picking up the phone.

Receipts and invoices showing the original terms and the price you agreed to.
Emails or chat transcripts with the merchant, including dates and any response — or lack of one.
Carrier tracking records showing non-delivery, delivery to a different address, or a label that never moved.
Clear photos of damaged, wrong, or defective goods, with something for scale if the defect isn’t obvious.
Any written contract or service agreement if the dispute involves services that weren’t delivered as promised.

Send copies and keep the originals. If you’re filing on paper, keep a copy of everything you send. If you’re filing online, save the confirmation screen and the reference number. Disputes closed for “insufficient evidence” are common and almost always preventable.

Where to Send It

This is where most people make the mistake that costs them the federal protections. Your written notice has to go to the address the issuer designates for billing inquiries. That address appears on your statement, usually near the top or on the back, and it is almost never the same address you send payments to.¹ A dispute mailed to the payment address can be treated as ordinary correspondence rather than a formal billing error notice, which means the Fair Credit Billing Act’s timelines and protections may never kick in.

If you’re mailing a paper form or letter, use certified mail with return receipt requested. That gives you dated proof the issuer received it. The statute also says you can’t submit the dispute on a payment stub unless the issuer’s own disclosures permit it.

Filing Online or by Phone

Most major issuers let you open a dispute through their website or app by selecting the transaction and choosing a dispute option. These channels are convenient and issuers generally treat them like written notices. The statute, though, specifically references written notice sent to the billing inquiry address. For a large disputed amount, or any time you want the strongest legal footing, follow the online submission with a mailed letter. Either way, screenshot the confirmation and save the reference number.

After You File

Federal law puts the issuer on a clock. It must send you a written acknowledgment within 30 days of receiving your dispute, unless it resolves the matter in full within that same 30 days. It then has two complete billing cycles, and no more than 90 days total, to finish investigating and either correct the error or explain in writing why it believes the original charge was right.¹

While the investigation is open, the issuer cannot try to collect the disputed amount, require you to pay it, close or restrict your account because of it, or report it as delinquent to credit bureaus. Your statements may still show the charge and even finance charges accruing on it, but the issuer has to note that payment is not required during the investigation.⁶ Many issuers go further and post a provisional credit so the amount doesn’t tie up your available balance.

If the investigation goes your way, the issuer removes the charge and any related finance charges and sends you written confirmation. If it goes against you, you’ll get a written explanation and, on request, copies of the documentary evidence the issuer relied on. At that point you owe the original amount plus finance charges that built up during the investigation. You have at least 10 days from receiving the explanation before the issuer can report the balance as delinquent, and if you write back disagreeing, any credit bureau report must note that the amount is disputed.

If the Issuer Breaks the Rules

An issuer that skips the 30-day acknowledgment, blows past the 90-day investigation deadline, or tries to collect while the dispute is pending forfeits the right to collect the disputed amount and related finance charges, up to a $50 cap. That forfeiture applies even if the underlying charge turns out to have been legitimate.¹

You can also sue. For credit card accounts the statute allows recovery of twice the finance charge on the transaction, with a floor of $500 and a ceiling of $5,000, plus actual damages and reasonable attorney’s fees.⁷ If informal escalation inside the bank goes nowhere, a complaint to the Consumer Financial Protection Bureau is the next step before litigation.

A Note on Quality-of-Goods Claims

The chargeback dispute form covers billing errors. A separate FCBA provision lets you withhold payment from the issuer when goods or services bought with the card are defective or not as described, but it carries its own conditions: a good-faith attempt to resolve the issue with the merchant first, a purchase over $50, and a transaction in your home state or within 100 miles of your billing address. Those dollar and geographic limits drop away when the merchant and issuer have a special relationship, such as common ownership or a co-branded solicitation that led to the purchase.⁸ For online purchases from a distant seller, the cleaner path is usually to file a standard billing error dispute for undelivered goods or items not as described, using the same form and process above.
