A chargeback is when your credit card company reverses a charge. The term shows up in conversations about fraud, missing packages, and regrettable online purchases, and it sounds like one thing. In practice, it is both a process and an outcome. A billing error, by contrast, is a legal category defined by the Fair Credit Billing Act of 1974 and enforced by the Consumer Financial Protection Bureau. The two terms overlap in daily use, but they start from different rules and follow different steps. Knowing which path you are on can make a difference when you spot a problem on your statement.
The CFPB presents a chargeback request and a formal billing error notice as separate options. Both can reverse a charge, and both depend on federal consumer protections, but the billing error rules come from a specific statute. That statute, the Fair Credit Billing Act, is an amendment to the Truth in Lending Act. Regulation Z implements it. When you file a formal billing error notice, you are invoking those rules, and the card issuer owes you certain responses on a fixed timeline. A chargeback request may follow similar steps, but the term itself does not carry the same statutory weight. The FCBA is described as the foundation for much of the credit card dispute process, so understanding what counts as a billing error under the law is useful even if you never write a formal notice.
The line between the two is not always obvious. Many people use the word chargeback for any card dispute, and many disputes do end with a reversed charge. But the formal definition of a billing error is narrower than the everyday sense of a problem with your bill. The rest of this piece walks through that definition, the deadlines that apply, and the steps the CFPB recommends. It also flags the gaps in the public guidance, so you know where to check for current rules that fit your situation.
What the Law Calls a Billing Error
Under the FCBA, a billing error includes four main categories. The first is an unauthorized charge. The second is a charge for the wrong amount. The third is a charge for goods or services you never received or did not accept. The fourth is an arithmetic or accounting mistake on your statement. These categories are the legal definition, so a problem that fits one of them is a billing error regardless of how the seller responds or what the card company calls it.
Charges for a purchase you did not receive, or did not accept delivery of, can count as a billing error. This is why a missing order is treated differently from a product that arrived but disappointed you. A quality complaint about a delivered item usually depends on the seller's return terms and the card company's chargeback rules rather than the billing error rules. The distinction matters because the FCBA sets out specific rights when a billing error has occurred, and those rights do not apply to every dispute.

Unfamiliar charges deserve a close look. The CFPB advises reviewing each statement every month for items you do not recognize, including optional fee-based add-on products that may have been added without a clear request. A charge you did not authorize is one of the four FCBA categories, and a charge you do not recognize is often the first sign of a billing error or fraud. Compare your starting balance with the previous month's bill as part of that review. Arithmetic mistakes can appear as a balance that does not match the sum of the charges and payments, and those mistakes also count as billing errors under the law.
Deadlines and What the Card Issuer Must Do
A written billing error notice generally needs to be sent within 60 days of the statement on which the charge first appeared. Missing that window can limit your options, so note the statement date as soon as you spot a problem. The 60-day clock runs from the statement date, not the date you opened the envelope or logged in to check your account. If you wait to review old statements, the deadline may have passed before you start.
Under the FCBA, the card issuer must acknowledge a billing dispute within 30 days of receiving it. It must investigate and resolve the dispute within two complete billing cycles, and no later than 90 days after receipt. These are the statutory limits for billing error notices, and they describe what the issuer owes you rather than a guaranteed result. The investigation can end with the charge reversed, with the charge upheld, or with a partial adjustment. The timeline is fixed, but the outcome is not.
While an investigation is open, the issuer generally cannot require payment of the disputed amount. You do not have to pay the disputed charge or related finance or other charges during the investigation, but you must still pay the undisputed parts of your bill on time. This is a key protection under the FCBA. If you skip the entire minimum payment because one charge is in dispute, you can still be reported late on the rest of the balance. The law protects you from paying the disputed amount, not from paying the bill.
Steps to Take Before and After Filing
The CFPB presents contacting the seller as the first step. Explain the problem, ask for a refund or for the charge to be reversed, and give the seller a chance to fix it. Many issues end here, and a written record of that conversation can help if you later file with the card company. An email, a chat transcript, or notes from a phone call can all serve as evidence that you tried to resolve the issue directly.
If the seller does not resolve the issue, contact your card company about disputing the charge. The CFPB describes a five-step approach. First, review your statement every month. Second, call the customer service number or file a dispute online. Third, follow up with a letter. Fourth, pay undisputed charges. Fifth, keep records. Each step supports the next, and skipping one can slow down the process or weaken your case.
A written billing error notice should include your name, address, account number, and a clear explanation of what you believe is wrong and why. Keep a copy as proof. The address for billing disputes can differ from the address where you send payments, so check your statement before mailing anything. Some card companies print two addresses on the bill, one for payments and one for disputes. Sending a dispute letter to the payment center can delay the acknowledgment and eat into the 60-day filing window.
Your credit card agreement may also describe how the company handles billing errors, and it is worth reading that section. The agreement will tell you whether the company accepts disputes online, what information you need to provide, and how it counts days for the purposes of the FCBA timeline. The agreement is a legal document, and the dispute section is one of the few parts you may actually need to consult while you hold the card.
What the Guidance Does Not Say
The available sources do not describe the card network chargeback process step by step, and they do not say whether networks use timelines that differ from the FCBA billing error timeline. Treat any specific network rule you hear about as unconfirmed until you check your card issuer's terms. The FCBA sets a floor for consumer rights, but card networks and issuers can offer more generous procedures. The reverse is also possible: a chargeback request that does not meet the FCBA definition of a billing error may be handled under the issuer's own policies rather than the statute.
The full text of the Regulation Z billing error provision is not captured in the source material, and the conditions for withholding payment on a partly paid purchase are cut off. The sources also say a possible right to withhold payment applies only when certain conditions are met, including a good-faith attempt with the seller and a purchase made in your home state or within 100 miles of your home address, but they do not explain what good faith means in practice. That gap matters if you are trying to decide whether you can stop paying for a product that was delivered but defective. The statutory language is in 12 CFR 1026.13, and you can read it on the CFPB website if you need the full rule.
The sources do not explain how a dispute, chargeback, or billing error affects credit reports or credit scores, how debit card dispute rights compare, or what happens after a dispute is resolved against the cardholder. For those questions, the CFPB and FTC consumer pages are the most reliable places to check current guidance. The CFPB's Ask CFPB tool and the FTC's consumer advice section both cover disputes, and both agencies update their guidance as rules change. If your question is not answered here, start with those official sources or consult a qualified professional who can look at your specific situation.
