Prepare the records before you submit
Read your actual statement and distinguish the purchase date from the posting date and statement sending date. Record the complete descriptor without assuming that a matching brand proves authorization. Compare it with receipts and any cancellation or refund correspondence you have. Select only a reason that describes your circumstances.
Read every sentence in the generated letter. Replace placeholders, correct anything that does not apply, and remove assertions you cannot support. Keep your own copy and retain the issuer’s receipt or case reference. An editable template helps with preparation; it cannot contact the merchant, file a chargeback or decide the outcome.
Check the submission channel
Use your bank’s official app, the contact details on your card, or its published billing-error instructions. Ask which documents and account identifiers it needs. Avoid sending a full card number or unrelated identity documents to a generic email address. Do not wait to report suspected unauthorized activity while gathering every exhibit.
For credit billing errors, confirm the disclosed notice address or agreed electronic method. For debit transfers, ask whether an oral report needs written confirmation. A PDF saved on your device is a record of your draft, not proof of receipt. The issuer’s acknowledgement and investigation response are separate records to retain.
What this tool cannot determine
The account type, transaction history and notice circumstances can affect the applicable procedure. The tool does not compute lost-card liability, guarantee provisional credit, confirm an accepted dispute or promise reimbursement. Its date calculation is a reference based on your input. If that reference has passed, contact your issuer anyway to ask which options apply.
Official rules and limitations
Consult the CFPB’s credit billing-error procedures and electronic-transfer error procedures. These sources were checked on October 7, 2026 for the distinctions explained here. No specialist legal review is claimed.
Frequently asked questions
Why does the tool add 60 days to the statement date?
It produces a calendar reference from the sending date you enter for the first statement showing the error. It does not calculate every deadline or decide whether notice is timely. Lost or stolen debit access devices involve separate rules.
Does email count as written notice?
Use the address or electronic method your creditor has agreed to for credit billing-error notices. A generic email address or a saved PDF does not prove proper receipt. Debit error notice can be oral or written.
What should I include with the letter?
Start with the disputed descriptor, amount, date and the reason you believe it is wrong. Add relevant statements, receipts or correspondence through the issuer’s secure process. Ask which account identifiers it requires; avoid unnecessary sensitive information.
