Bank / credit card chargeback dispute letter

← All templates

Calling your bank or tapping "dispute this charge" in your card app starts the process, but for many disputes it is not the whole process. Two federal regulations govern how banks and card issuers must handle these disputes, and both are built around a written notice from you — not just a phone call or an in-app flag.

Regulation E vs. Regulation Z

Regulation E covers debit cards, ATM transactions, and other electronic funds transfers. It requires you to notify your bank of an error, and while you can start that notice orally, the bank can require written confirmation within a set number of business days to keep your provisional-credit rights intact. Regulation Z covers credit cards and requires a written billing-error notice sent to the address your issuer designates for disputes — a phone call alone does not start the formal error-resolution clock. Which rule applies depends on how you paid, and issuers apply their own house policies on top of the federal floor, so read your card agreement or ask your issuer which written-notice requirements apply to your account.

Why a phone or app dispute alone may not be enough

An app-based dispute is convenient, but it leaves you with no independent proof of what you said or when you said it, and no proof the bank actually received a written notice if the matter escalates. If your initial dispute is denied, or the issuer claims it never received your notice, having mailed a written letter — with a delivery record — is often the difference between a dispute that gets reopened and one that is closed for good. Deadlines here are commonly around 60 days from the relevant statement date, but they vary by regulation, transaction type, and issuer, so do not wait to send written notice if you think you may need it.

How sending it here works

• Open the template, fill in the merchant, transaction date, amount, and reference number, and describe the basis for the dispute.
• Pay $14.99 (Certified + electronic Return Receipt) — we print and mail it by USPS the next business day.
• Keep the tracking link and the electronic Return Receipt as your dated proof of delivery if the issuer later questions the timeline.

This template and page are provided as a convenience, not legal advice. Whether Regulation E, Regulation Z, or another rule applies to your situation — and what deadlines and remedies you have — depends on your specific account and transaction. If you are unsure, consult your card agreement, your issuer's disputes department, or a consumer-law attorney before relying on any deadline mentioned here.
