How to dispute a credit card billing error under the FCBA (Regulation Z)

What Is the FCBA and Why Does It Apply to Credit Card Bills?

The Fair Credit Billing Act is part of the Truth in Lending Act. Its billing-error rules are codified at 15 U.S.C. § 1666 and fleshed out in Regulation Z at 12 CFR § 1026.13. Together, these rules create a mandatory dispute process that creditors must follow — and meaningful consequences when they don’t.

The process covers open-end revolving accounts, which includes most consumer credit cards. It is separate from, and in addition to, any voluntary dispute process a card issuer may advertise.

What Counts as a Billing Error Under the FCBA?

Not every complaint about a charge qualifies as a billing error under the statute. Regulation Z § 1026.13 identifies specific categories, which the CFPB summarizes to include:

• A charge for the wrong amount
• A charge for goods or services that were never delivered or that the consumer did not accept
• A math mistake on the statement
• A charge the consumer did not authorize
• A creditor’s failure to properly credit a payment

If a dispute falls into one of these categories, the formal FCBA process applies. If the consumer simply disagrees with the quality of a product or service, that may still be disputable — but the FCBA’s specific procedural protections and creditor obligations are most clearly triggered by the categories above.

Key Deadlines at a Glance

The 60-day consumer deadline is the most consequential. Missing it may forfeit the FCBA’s specific procedural protections, including the creditor’s obligation to investigate and the prohibition on collection activity during the dispute period.

How to Send a Valid Billing-Error Notice

Step 1: Check the Statement for the Creditor’s Billing-Error Address

Regulation Z § 1026.13 requires the notice to go to the address the creditor discloses specifically for billing-error disputes — not necessarily the general payment address. That address typically appears on the back of the monthly statement. Using the wrong address can undermine the formal FCBA timeline.

Step 2: Write a Brief, Specific Letter

The notice must be in writing. Key information to include:

• Your full name and account number
• The specific charge(s) being disputed (date, amount, merchant name)
• A brief statement of why the charge is a billing error (e.g., “I did not authorize this charge” or “The goods were never delivered”)

The CFPB advises sending the letter by certified mail and keeping a copy of everything sent.

Step 3: Send the Notice Within 60 Days of the First Statement

Regulation Z § 1026.13 requires that the consumer’s billing-error notice be received by the creditor no later than 60 days after the creditor transmitted the first periodic statement reflecting the alleged error. Counting from statement transmission date — not the date the consumer opened it — is the standard the rule uses.

Step 4: Continue Paying Undisputed Amounts

The FTC’s consumer guidance states that while the issuer is investigating, consumers can withhold payment on the disputed amount and related charges, but are expected to pay any part of the bill not in question. Withholding payment on undisputed balances may affect a consumer’s account standing and does not fall within the FCBA’s protection.

Step 5: Monitor the Creditor’s Response

Under 15 U.S.C. § 1666, a creditor that receives a written billing-error notice must send a written acknowledgment within 30 days of receipt, unless it resolves the dispute within that same 30-day window. The CFPB confirms this: the credit card company has 30 days to tell the consumer it received the letter, then gets up to two additional billing cycles to finish the investigation.

What the Creditor Must — and Cannot — Do During the Dispute

Once a valid written notice is received, the creditor operates under strict rules for the duration of the investigation period.

The creditor must: - Acknowledge the notice in writing within 30 days (15 U.S.C. § 1666) - Resolve the dispute within two complete billing cycles, and in no event later than 90 days (15 U.S.C. § 1666) - Notify the consumer in writing of the outcome

The creditor may not: - Try to collect the disputed amount during the investigation period - Institute court action, take a lien, or institute attachment proceedings on the disputed amount - Report the disputed amount as delinquent to a credit reporting agency without noting that it is disputed

Regulation Z § 1026.13 explicitly prohibits collection action on the disputed amount during the error-resolution period, including court actions, liens, and attachment proceedings.

What Happens If the Creditor Doesn’t Follow the Rules?

Under 15 U.S.C. § 1666, a creditor that fails to comply with the billing-error procedures forfeits its right to collect the disputed amount and any finance charges on it. The statute caps that forfeiture at $50 per violation.

This consequence applies even if the creditor’s investigation would ultimately have shown the charge was valid. The forfeiture is tied to the creditor’s failure to follow procedure, not solely to whether the underlying charge was correct.

Consumers who believe a creditor has violated these procedures can submit a complaint to the CFPB. The CFPB says companies provide an initial response to a complaint within 15 calendar days. More information on how that process works is available on the BEST-AI-LAWYER home page alongside guidance for disputes involving banks and other financial service providers.

Disputing the Error vs. Disputing a Credit Report Entry

The FCBA billing-error process governs the relationship between a consumer and their card issuer. It is separate from the dispute process that applies when a billing error results in a negative entry on a consumer’s credit report. If the creditor reported the disputed amount as delinquent without noting it was contested — and a credit reporting agency picked that up — that situation may also involve rights under the Fair Credit Reporting Act (FCRA), which has its own timelines and procedures. Those are distinct from the FCBA process described on this page.

Frequently Asked Questions

Can a phone call start the FCBA dispute clock?

No. Regulation Z § 1026.13 requires a written notice. A phone call to the card issuer does not trigger the creditor’s formal obligations under the FCBA, including the prohibition on collection activity and the investigation deadline.

What if I miss the 60-day deadline?

Regulation Z § 1026.13 specifies that the notice must be received within 60 days of the first statement reflecting the error. Missing that window means the consumer generally cannot invoke the FCBA’s formal protections for that particular error. Consumers may still have other options through the card issuer’s internal process or, in some cases, through state consumer-protection law — but the federal FCBA procedural rights described here are time-bound.

Does the FCBA apply to debit cards?

No. The FCBA applies to open-end revolving credit accounts such as credit cards. Debit card disputes are governed by a different federal law, the Electronic Fund Transfer Act (EFTA), which has different notice deadlines and different creditor obligations. The two statutes should not be confused.

What is the maximum the creditor forfeits for a procedural violation?

Under 15 U.S.C. § 1666, the forfeiture of the right to collect the disputed amount and related finance charges is capped at $50 per violation, even if the disputed amount is higher.

Where exactly do I send the written notice?

Regulation Z § 1026.13 requires the notice to go to the address the creditor specifically discloses for billing-error notices. That address typically appears on the periodic statement itself and may differ from the payment remittance address. Sending a dispute to the wrong address may not start the formal FCBA clock.

Can the creditor report the disputed charge as delinquent while investigating?

Under Regulation Z § 1026.13, the creditor is prohibited from reporting the disputed amount as delinquent during the error-resolution period without noting that the amount is disputed. Reporting without that notation would violate the FCBA’s procedural rules.
