How to File a Credit Card Billing Dispute With Your Bank

To file a credit card billing dispute with your bank, send a written dispute letter to the billing inquiry address on your statement within 60 days of the date the statement was mailed, identifying the charge and explaining why it’s wrong. That written notice is what triggers the Fair Credit Billing Act’s investigation deadlines and payment protections. A phone call or a tap on the “dispute this charge” button in your bank’s app may get the problem fixed, but it does not, on its own, put the law behind you.

You Have 60 Days From the Statement Date

The clock starts the day your bank sends the statement containing the error. Not the day you spot the charge, and not the day the transaction posted.¹ An unauthorized charge buried in a long statement can easily slip past for two months, and once the window closes, the bank has no legal obligation to investigate or to shield you from collection on the disputed amount. Many banks will still look into late disputes as a courtesy, but courtesy is not a right.

Review every statement when it arrives. If something looks off, start the dispute the same week.

Why Written Notice Is the Step That Counts

The Fair Credit Billing Act requires a written notice sent to the bank’s designated billing inquiry address. Only after the bank receives that notice do the legal timelines and protections kick in.² Your bank’s phone line and dispute button are faster, and they often resolve the problem without any further effort. But if the dispute drags on or the bank denies it, you’ll want the statutory framework behind you, and a phone call may not get you there.

The safest approach is to do both. Use whatever quick channel the bank offers, then send a formal written notice to the billing inquiry address so the clock on the bank’s legal obligations starts running.

What Your Dispute Letter Must Contain

The statute sets a minimum: your name, your account number, the dollar amount you believe is wrong, and an explanation of why you think the statement has an error.² Go beyond that minimum. Investigators work through hundreds of records, and vague descriptions slow everything down.

The exact merchant name as it appears on your statement
The transaction date
The precise dollar amount, down to the cent
One clear sentence identifying the type of error (“I did not authorize this charge,” “I returned this item and never received a credit,” “I was charged $89 but the agreed price was $59”)
Copies of supporting evidence: receipts, delivery tracking, merchant emails, return shipping labels, advertisements, written agreements

Keep copies of the letter and every attachment. Don’t send originals.

Where and How to Send It

Send the letter to the billing inquiry address printed on your statement. This is not the same address you use for payments.¹ Look for it near the fine print about disputes or billing questions.

Mail the letter by Certified Mail with a Return Receipt. Certified Mail costs $5.30 on top of regular postage. A hard-copy Return Receipt adds $4.40, and the electronic version runs $2.82.³ The receipt gives you signed, date-stamped proof the bank received your notice inside the 60-day window. If the bank later claims the letter never arrived, that proof ends the argument.

Which Problems Qualify for a Billing Dispute

Not every grievance about a charge qualifies as a billing error. The Fair Credit Billing Act covers specific categories:²

Charges you did not authorize
Charges for the wrong amount
Charges for goods that never arrived or showed up materially different from what the merchant promised
Missing credits for returns or payments that don’t appear on your statement
Computational mistakes on the bill

One boundary worth knowing: simple quality complaints, like a product that broke after a week or a contractor who did sloppy work, don’t fit the billing error process. Those run under a separate “claims and defenses” provision that requires you to try resolving the problem with the merchant first and generally applies only to purchases over $50 made in your home state or within 100 miles of your billing address.⁴ For a true billing error, you go straight to the bank; for a quality dispute, you start with the merchant.

What the Bank Must Do After Receiving Your Notice

Two deadlines start running once your written notice arrives. The bank must send a written acknowledgment within 30 days unless it resolves the dispute entirely in that time. The full investigation must finish within two complete billing cycles, with an absolute outer limit of 90 days.¹

While the investigation is open, you don’t have to pay the disputed portion of your bill. The bank cannot collect it, charge late fees on it, or add related interest.⁵ It also cannot report the disputed amount as delinquent to the credit bureaus. Pay everything else on time, though. Holding back your entire payment because of one disputed charge will generate legitimate late fees on the rest of the balance.

Many banks issue a temporary credit for the disputed amount while they investigate. That’s a practical courtesy, not a legal requirement for credit card disputes. If the bank finds in your favor, the credit becomes permanent and any related finance charges are removed.

If the Bank Rules Against You

A denial comes with a written explanation. Request copies of the documents and evidence the bank relied on.¹ Investigations sometimes miss things or rely on merchant records that contradict what actually happened.

Once you’re notified, the disputed amount returns to your bill along with any finance charges that accumulated during the investigation. The bank must give you at least 10 days to pay, and if your account normally has a grace period, that grace period applies before new interest is added.⁵ Pay within that window and the bank cannot report the amount as delinquent.

Appealing to the Bank

If you still believe the charge is wrong, send a second written notice within the payment deadline or within 10 days of receiving the explanation, whichever gives you more time. After that, the bank may report the amount as delinquent, but it must also report that the amount is disputed and tell you the name and address of every party it reports to.⁵ If the dispute is later resolved in your favor, the bank has to update those same parties.

Filing a Complaint With the CFPB

When the bank’s internal process fails you, the Consumer Financial Protection Bureau accepts formal complaints. File online at consumerfinance.gov in about 10 minutes, or call (855) 411-2372 on weekdays between 9 a.m. and 6 p.m. ET.⁶ Include the key dates, dollar amounts, and any correspondence with the bank, and attach supporting documents up to 50 pages. Companies generally respond within 15 days, with a final response due within 60 days.

You generally cannot submit a second complaint about the same problem, so put everything relevant in the first one. The CFPB publishes complaint data in a public database, which tends to focus banks’ attention.
