Mastercard Chargeback Reason Code 4837: No Cardholder Authorization



Description

A card-not-present transaction occurs when cardholder files a complaint that he/she neither participated nor authorized a particular charge. A card-not-present transaction occurs on a fictitious account number on which owner’s authorization was not obtained. Telephone sales, mail-order, Internet/online sales, monthly subscriptions, recurring and prepayment transactions are examples of card-not-present transactions. Mostly this situation occurs when someone fraudulently uses someone else’s credit card and processes card-not-present transaction without the consent or permission of the cardholder. Sometimes, cardholder does not recognize a card-not-present transaction on his statement because of invisible, unclear or confusing merchant or product name.

Evidence Required

• If the transaction was a mobile order, telephone order or Internet transaction and an authorization approval was received and address verification was made that matched cardholder’s street address and ZIP code, and that the evidence can be provided about the product delivery to the correct address as per AVS query, send the POD, order receipt and any additional documents related to the transaction.
• If the transaction was processed without use of address verification system (AVS) send a copy of the order receipt, proof of delivery (POD) with the sign of cardholder on it and the other documents explaining the product and complete transaction details.
• If the transaction was processed in card present environment, this chargeback would be invalid, in this case, prove that the cardholder participated in the transaction by providing order receipt showing the card imprint and cardholder’s signature.

Common Examples:

1. Linda goes to a café after work and orders a coffee and a muffin. She later realizes that she left her wallet in her drawer in the office so she asks the cashier to enter her card details manually. The cashier processes the transaction but, forgets to take her signatures or imprint on the receipt. Later, when Linda checks her account she sees a larger amount on her statement than what she expected to see from the transaction. She therefore, disputes the amount under the Reason Code 4837: No Cardholder Authorization.
2. George leaves his wallet home and goes for a jog. Looking for the opportunity his daughter Nia slips out his card and shops for her Prom night. Later in the week, George checks his account to find out an unknown transaction to an online accessory merchant. Thinking it as a fraud he disputes the amount under the Reason Code 4837: No Cardholder Authorization.
