Federal rules cover billing errors, not every bad purchase
Did the merchant fail you, or did the bill go wrong?
The Fair Credit Billing Act, implemented through Regulation Z, gives U.S. cardholders a formal process for certain billing errors. Issuers and card networks may run separate dispute procedures. Those workflows do not always match the federal path.
This applies to U.S. consumer credit cards, while debit cards, prepaid cards, wire transfers, and P2P payments have different rules.
| What happened | Route that may apply | First sensible move |
|---|---|---|
| You do not recognize the transaction or lost your card | Unauthorized-use protections and a billing-error notice | Contact the issuer immediately and secure the account |
| The amount, date, or transaction is wrong, duplicated, or a payment was not credited | FCBA billing-error process | Send a written billing-error notice |
| Goods or services never arrived as agreed, or were not accepted on delivery | It may qualify as a billing error | Save the order, delivery records, and merchant messages |
| A subscription renewed after you canceled | Issuer and card-network dispute review, based on the facts | Keep cancellation confirmation and the renewal charge |
| A delivered product was defective or disappointing | Merchant refund or contract dispute; separate rights may sometimes apply | Ask the merchant to resolve it and document the request |
Act quickly if a charge is not yours. A canceled subscription, late delivery, or defective item needs different proof and may follow a different route.
A refund request is not a billing-error notice, and a chargeback is not a court ruling.
Protect the 60-day billing-error deadline
The 60-day clock for an FCBA billing-error notice starts when the issuer sent the first periodic statement that shows the error. It does not start on the purchase date. Payment due dates do not start it either.
Your written notice has to reach the issuer inside that window. Both the FTC's credit card dispute instructions and Regulation Z's billing-error rule use this statement-based deadline.
- Call the issuer right away if you suspect fraud, and ask it to secure or replace the card.
- Find the first statement that shows the charge and mark the 60-day deadline.
- For a merchant problem, request a resolution if practical and save the response.
- Mail the billing-error notice before the deadline, even if the merchant has not replied.
- Keep a simple file with the statement, letter, delivery confirmation, and supporting records.
Mail the letter to the billing-inquiries address printed on your statement. That address can differ from the payment address.
An app, chat, or phone report may start the issuer's review. Don't assume an oral report alone preserves the formal federal protections. Keep a copy of the letter. Keep proof that it was sent.
If statements went to an old address, a narrow rule applies. The issuer generally must have received your written change of address at least 20 days before the billing period ended.
Write a notice the issuer can investigate
You don't need legal language. Regulation Z requires enough information for the issuer to identify the account, the amount in question, and the reason for the dispute. Make the problem easy to spot.
Subject: Notice of billing error
I dispute the $[amount] transaction shown on my [statement date] statement from [merchant]. I believe it is a billing error because [brief reason]. Please investigate and correct my account. My account number is [account number].
Name any attachments, such as an invoice, cancellation email, or tracking record. Keep the letter factual. A clear timeline beats a long, angry explanation.
What happens while the issuer investigates
After the issuer gets your written notice, it must acknowledge the dispute within 30 days unless it already fixed the problem. The investigation still has a hard stop.
It must finish within two complete billing cycles, and no later than 90 days after receiving your notice. You don't have to pay the disputed amount or related finance charges while that review is pending. Keep paying the undisputed part on time.
Thing is, a provisional credit is not a final decision, and an issuer may issue one under its own procedures, but federal billing-error rules do not guarantee a temporary credit within five or 10 days, and that credit can be removed if the issuer concludes there was no error after its review.
If the issuer finds no error, it must explain the decision in writing. Ask for the documents supporting that conclusion within 15 days of receiving the explanation.
Handle fraud and merchant problems differently
Federal law generally limits liability for unauthorized credit-card use to $50 in qualifying circumstances, and many issuers and card networks advertise zero-liability coverage as a company or network policy. Don't delay reporting because of that policy.
Check for a confusing merchant descriptor or a purchase by an authorized user, and do it quickly.
Report a genuinely unauthorized charge to the issuer as soon as you see it. A police report is not part of the federal billing-error notice requirements, though an issuer may ask for more information in some cases.
Keep the original terms, your cancellation request, confirmation, and each later charge if a subscription billed after you canceled. That file is not the same as a stolen-card file. Those records can show whether the merchant had notice before billing again.
A delivered but defective product is also different. It's not automatically a billing error.
In some situations, you may be able to assert claims and defenses against the issuer after making a good-faith effort to resolve the issue with the seller. Transaction amount and location conditions can matter. The FTC discusses these limits in its credit card dispute guidance.
Keep records that match the problem
Match the file to the problem. An unauthorized charge and a missing package do not need the same paper.
| Dispute reason | Records that can help |
|---|---|
| Unauthorized transaction | Statement entry, messages with the issuer, card replacement details, and notes of when you reported it |
| Goods not delivered | Order confirmation, promised delivery date, tracking, and merchant correspondence |
| Canceled subscription | Cancellation confirmation, plan terms, account screenshots, and post-cancellation charges |
| Duplicate or incorrect amount | Receipt, invoice, order confirmation, and statement showing both charges |
| Product not as described | Photos, product listing, return request, and merchant response |
Turns out, a boring chronology can be more useful than a folder full of screenshots: note when you ordered, when delivery was promised, when you contacted the merchant, what it said, and when the charge appeared, because the dates often decide what route the issuer can review.
Photos of a defect may support a merchant complaint, but they do not by themselves prove an FCBA billing error. Leave those files unchanged.
For an item you never received, the FTC also has guidance on charges for merchandise that did not arrive.
Card-network chargebacks do not replace federal rights
The FCBA is federal law. A chargeback is an industry process between card issuers, card networks, and merchants. They can overlap, but they are not identical.
A Visa, Mastercard, American Express, or Discover logo does not set one universal deadline for your case.
Network procedures can depend on the dispute reason, transaction date, delivery date, cancellation date, and the issuer's own workflow. Ask the issuer which process it is using and what deadline it is applying. Find out what evidence it needs.
Don't rely on a generic online table promising the same time limit or provisional credit for every card. The issuer that sends your statement remains responsible for handling a valid federal billing-error notice.
A merchant may later challenge the dispute through its payment process, and you may not see every document exchanged behind the scenes.
If the issuer rejects your dispute
To be honest, a denial letter won't always close the file. Read the reason closely and compare it with your records.
- Check whether the issuer misunderstood the charge, date, merchant, or cancellation timeline.
- Request the documents and explanation used to reach the decision.
- Send any new evidence through the issuer's stated review or reconsideration process.
- File a complaint with the Consumer Financial Protection Bureau if the issue is the issuer's handling of a federal billing-error dispute.
There is no universal FCBA appeal deadline. You'll need to ask the issuer how to request a review, then follow that instruction in writing.
If the problem is mainly a merchant refusing to honor a cancellation, refund, warranty, or delivery promise, a state consumer-protection office may also be relevant. That is separate from the issuer's federal billing-error process.
Pull the first statement that shows the charge and mark the 60-day date. Send a clear written notice to the billing-inquiries address with copied proof. Keep paying the undisputed balance while the case is pending.
