A wrong number on a credit-card statement is not something an account holder simply has to swallow. A federal law written for exactly this problem, the Fair Credit Billing Act, gives cardholders a formal window to challenge a charge and forces the issuer to prove the amount before collecting on it. The clock is short and specific: a written dispute must reach the issuer within 60 days of the statement that carried the error. Used in time, the law shifts the burden of proof onto the bank and freezes the disputed sum until the question is settled.
What counts as a billing error under federal law
The Fair Credit Billing Act does not cover every disappointment on a statement, but its definition of a billing error is broader than many cardholders assume. It reaches charges the customer never made, amounts entered incorrectly, purchases billed on the wrong date, and math or accounting mistakes. It also covers goods and services that were ordered but never delivered, or that arrived in a condition materially different from what was agreed, which pulls many online and mail-order disputes into its protection.
Timing is the hinge. The dispute must be sent in writing and must arrive within 60 days after the issuer mailed or delivered the first statement showing the error. The Federal Trade Commission spells out the 60-day deadline and the written-notice requirement, and it warns that a phone call alone does not preserve the full legal rights the statute grants. A dated letter, sent to the address the issuer lists for billing inquiries rather than the payment address, is what starts the process.
The distinction between a billing error and simple dissatisfaction matters for older cardholders in particular, who are frequent targets of subscription traps and charges that quietly renew. A gym membership that keeps billing after cancellation or a “free trial” that converts to a monthly fee can both qualify, provided the notice goes out inside the window and identifies the amount and the reason in writing.

What the issuer must do once the letter lands
Sending the notice triggers a sequence the issuer cannot ignore. The company must acknowledge the dispute in writing within 30 days of receiving it, unless it has already fixed the problem, and it must resolve the matter within two billing cycles — never more than 90 days. During that stretch the cardholder does not have to pay the disputed amount or any interest that accrues on it, though the rest of the balance remains due on schedule.
The law also restrains what the issuer may do to the account while it investigates. It cannot report the disputed amount as delinquent to a credit bureau, and it cannot close or restrict the account solely because a charge is being contested. The Consumer Financial Protection Bureau tracks how card companies must handle these disputes, and those protections are automatic once a proper written notice is on file.
If the issuer finds the charge was an error, it must credit the amount along with any related fees and interest. If it concludes the charge was valid, it must explain that in writing and give the cardholder time to pay before treating the balance as past due. A customer who still disagrees can escalate, but the interim shield — no payment, no interest, no black mark — holds throughout the review.
The deadlines carry a penalty aimed at the issuer, too. A company that fails to follow the Fair Credit Billing Act’s procedures — missing the acknowledgment or resolution windows, for instance — forfeits its right to collect the disputed amount, up to $50, even when the charge later proves legitimate. That built-in consequence is what makes a properly filed dispute more than a complaint: it puts the card company on a clock with money riding on whether it answers in time.
Why the dispute right beats a chargeback request alone
Card networks offer their own informal “chargeback” process, and many customers reach for it first, but the statutory right carries teeth the voluntary system does not. A formal billing-error dispute invokes federal law rather than a network courtesy, which means the issuer’s obligations and the customer’s protections are enforceable, not discretionary. The two paths can run together, but the letter is what preserves the legal position if the matter ever escalates.
For a retiree reviewing statements on a fixed income, the practical value is a defined process with a hard deadline instead of an open-ended argument with a call center. Catching the error is the only step that depends on the cardholder; once the written notice goes out inside 60 days, the law does the rest of the work, holding the money in place until the bank can justify the charge.
The catch is entirely in the calendar. Miss the 60-day window and the strongest protections lapse, leaving a customer to rely on the goodwill of the issuer rather than a statute. The right exists on every account, but it belongs only to the cardholder who reads the statement in time and answers it in writing.
