A Chargeback Request Letter is a formal written notice sent by a cardholder to their bank or credit card issuer requesting the reversal of a disputed transaction. The letter initiates the chargeback process under the applicable card network's dispute resolution rules and, for credit card transactions, under the protections of the Fair Credit Billing Act (FCBA) (15 U.S.C. 1666) and its implementing regulation, Regulation Z (12 CFR 1026.13).

The FCBA establishes the legal framework for disputing billing errors on credit card accounts. Under the FCBA, a billing error includes charges for goods or services not received, charges for goods or services significantly not as described, unauthorized charges, charges in the wrong amount, and mathematical errors on the billing statement. The law requires the cardholder to send written notice of the billing error to the creditor's billing inquiries address within 60 days of the date the first statement containing the error was mailed.

For debit card transactions, the Electronic Fund Transfer Act (EFTA) (15 U.S.C. 1693) and Regulation E (12 CFR 1005) provide the regulatory framework. The EFTA limits a consumer's liability for unauthorized electronic fund transfers, with the extent of liability depending on how quickly the consumer reports the unauthorized transaction.

In addition to federal law, card network rules (Visa Core Rules and Visa Product and Service Rules, Mastercard Dispute Resolution Management, American Express Merchant Regulations, and Discover Network Operating Regulations) establish the procedures and reason codes for chargebacks. These rules define the specific dispute categories, documentation requirements, and time limits applicable to chargeback requests.

A Chargeback Request Letter is needed whenever a cardholder has been unable to resolve a billing dispute directly with the merchant and wishes to request that their bank or card issuer reverse the transaction. Common situations requiring a chargeback request include goods ordered but never delivered, services paid for but not provided, goods received that are defective or significantly not as described, duplicate charges for a single transaction, charges in an amount different from what was agreed, recurring subscription charges after the cardholder cancelled the subscription, unauthorized transactions on the cardholder's account, and transactions with a merchant that has ceased operations before fulfilling its obligations.

Before submitting a chargeback request, the cardholder should generally attempt to resolve the dispute directly with the merchant. Many banks require evidence that the cardholder has contacted the merchant and been unable to obtain a satisfactory resolution before they will initiate the chargeback process.

Timing is critical. Under the FCBA, the written notice of a billing error must be received by the creditor within 60 days of the date the first statement containing the error was mailed. Card network time limits are typically 120 days from the transaction date or expected delivery date. Failure to submit the dispute within the applicable time limit may result in the loss of chargeback rights.

A comprehensive Chargeback Request Letter must include several essential elements to comply with the FCBA and card network requirements and to maximize the likelihood of a successful dispute.

The letter must clearly identify the cardholder, including full name, address, and contact information. The card details section should specify the card type (Visa, Mastercard, American Express, or Discover), the last four digits of the card number, and the account number if different from the card number.

The transaction details must precisely identify the disputed charge, including the transaction date, the merchant name as it appears on the statement, the transaction amount, and any transaction reference number. Under Regulation Z (12 CFR 1026.13), the notice must contain sufficient information to enable the creditor to identify the cardholder's account and the billing error.

The dispute reason section should clearly state the grounds for the chargeback, aligning with the applicable card network reason codes. The detailed description should explain the facts of the dispute chronologically, including dates, communications, and actions taken.

The merchant contact section should document all attempts the cardholder has made to resolve the matter directly with the merchant, including dates, methods of contact, and responses received. This demonstrates good faith and supports the chargeback request.

The supporting documents section should list all enclosed evidence, such as bank statements, order confirmations, correspondence with the merchant, tracking information, and cancellation confirmations. The remedy section should clearly state the amount to be credited and request provisional credit during the investigation as permitted under the FCBA.
