Send your dispute letter to your card issuer, not to Visa or Mastercard. That mistake is common, and it can cost you the 60-day window. The issuer is the creditor under the Fair Credit Billing Act and Regulation Z. Your statement prints the correct address under "billing inquiries" or "billing disputes." Mail it there, and mail it early.
Under Regulation Z, 12 CFR 1026.13, the issuer generally has to receive your written billing error notice within 60 days after it sent the first statement showing the error. The statement date starts the clock, not the day you spotted the charge. Most people don't open a statement the day it lands. So look at the date printed on the paper itself.
Once the notice arrives, the issuer must acknowledge it within 30 days unless it fixes the problem sooner. Investigation takes up to two complete billing cycles, or 90 days at most. Miss those windows and the FCBA process loses teeth.
You can dispute an unauthorized charge, a duplicate charge, a wrong amount, or goods you never received. Step one doesn't need a lawyer. It needs a short letter, copies of your proof, and a calendar.

Re: Billing error dispute - Account ending [last 4 digits]
To Whom It May Concern:
I am writing to dispute a billing error under the Fair Credit Billing Act, 15 U.S.C. 1666, and Regulation Z, 12 CFR 1026.13.
Account ending: [last 4 digits]
Transaction date: [MM/DD/YYYY]
Merchant: [Merchant Name]
Amount: $[amount]
Reason for dispute: [For example: I did not authorize this charge. / This is a duplicate charge. / I was charged $X but the correct amount was $Y. / I paid for goods or services that were never delivered.]
I have enclosed copies of [list documents, such as your statement, receipt, order confirmation, cancellation email, or delivery tracking page].
Please investigate this billing error and, if the error is confirmed, correct my account by removing the charge and any related finance charges. Send me written confirmation of the correction. If you need more information, contact me at the phone number or email above.
Sincerely,
[Your Signature]
[Your Printed Name]What Counts as a Billing Error
Turns out the FCBA and Regulation Z cover more than obvious fraud. Accounting mistakes count. So do charges the statement fails to identify properly. The eCFR text of 12 CFR 1026.13 lists examples: a charge you or an authorized user never made, a payment the creditor failed to credit correctly, and a computational error on the creditor's side. A charge missing proper identification can qualify too.
A merchant's refund promise is a different animal. If you simply changed your mind, that's a return or cancellation problem. Your issuer might still push a chargeback through under card network rules, but the FCBA process isn't a general "I want my money back" button.
The practical line: if the charge is wrong, missing, duplicated, or unauthorized, write the letter. If it's buyer's remorse, start with the merchant's return policy.
How to Send the Letter and Track the Response
- Pull the statement that first showed the charge. Note the statement date. That date starts the 60-day billing error notice clock.
- Gather proof. A statement copy helps. Receipts, order emails, cancellation confirmations, and delivery tracking can help more.
- Fill in the template. Be specific about the amount, date, merchant, and why the charge is wrong. Skip the long emotional story.
- Print, sign, and copy the whole packet. Keep one copy for your files.
- Send it to the billing inquiries address on your statement. Use certified mail with return receipt requested if you want proof of delivery.
- Pay the undisputed part of your bill on time. The dispute process protects the disputed amount, not the rest of your balance.
- Mark your calendar. The issuer should acknowledge within 30 days unless it resolves the issue. Its investigation should end within two billing cycles, up to 90 days.
If the issuer corrects the error, check your next statement. The charge should be gone, and any related finance charge or interest should be gone with it. If the dispute is denied, the issuer must explain why and hand over the documents it relied on when you ask.
Short Templates for Common Disputes
Unauthorized charge
I did not make or authorize this charge. I did not give anyone permission to use my card for this transaction. Please treat this as a billing error under 12 CFR 1026.13(a)(1) and remove the charge.Double charge
This merchant charged my account twice for the same purchase. The first charge was $[amount] on [date]. The second charge was $[amount] on [date]. Please remove the duplicate charge.Wrong amount
I authorized a charge of $[correct amount] on [date], but my statement shows $[wrong amount]. I have enclosed a copy of the receipt showing the correct amount. Please correct the difference.Goods or services not received
I paid $[amount] on [date] for [item or service]. I never received it. The merchant's tracking information shows no delivery, and my attempts to resolve it with the merchant have not worked. Please reverse the charge.What Does Not Control Your Dispute
Thing is, the logo on your card doesn't decide your first step. Card network chargeback rules may matter later. You file the billing error notice with the issuer, and the issuer runs the investigation under federal law and its own procedures.
Certified mail helps. It isn't the law. Regulation Z wants written notice, not a particular mailing method. Certified mail mainly makes it harder for the issuer to claim it never got your letter.
A "no refunds" sign at the merchant's counter doesn't erase your right to dispute a billing error. It might affect a plain return. Keep those two issues apart.
If Your Dispute Is Denied
Don't stop at the first denial. Ask the issuer for the documents it used. Then reply with a short follow-up that answers the stated reason and adds any new evidence. Keep the same account number and dispute reference number on it.
You can also file a complaint with the Consumer Financial Protection Bureau. The CFPB sends it to the company and gives you a place to track the answer. Companies generally respond in 15 days, and you get 60 days to give feedback on that response. A CFPB complaint isn't a court case. It does create a documented escalation path.
If the card was lost or stolen, call the issuer right away. The FTC's lost or stolen card guidance says to report unauthorized charges as soon as you find them. For credit cards, federal law limits what you owe on unauthorized use. Follow the call with a letter so a paper trail exists.
FAQ
Do I have to use certified mail?
No. The FCBA requires written notice, and Regulation Z doesn't require certified mail. Certified mail with a return receipt is still a smart option. It gives you proof of delivery.
Can I dispute a charge after 60 days?
The strict 60-day deadline applies to the FCBA billing error notice. Miss it and call your issuer anyway. Explain what happened. For a lost or stolen card, report it immediately. The issuer may still help, but the billing error process is time-limited.
What if I used a debit card?
This letter is for credit card billing errors. Debit and prepaid card disputes follow different rules, mostly the Electronic Fund Transfer Act and Regulation E. Call your bank first and ask for its error resolution process.
