What is Chargeback Reason Code? Definition & Meaning - Ikajo Glossary


Chargeback Reason Code

A reason code or a chargeback reason code is a string of symbols (numbers and letters). These symbols stand for reasons why a financial institution may file a credit card chargeback from their client’s name. During this process, the representative of the institution examines the reasons’ list. Then it chooses the most applicable code for a particular situation.

The reason code marks particular reasons by numbers. Its main function is to outline the reason for the dispute around the transaction. Nevertheless, this series of actions can provoke a misunderstanding at the trader’s level, where there is no access to the RC assigning process.

All in all, chargeback codes identify frauds, authorization failures, and an incorrect amount of funds. Also, they identify processing errors and consumer disputes.

In addition, each type of reason code has many subtypes. Different sets of numbers indicate these subtypes.  

Why do we need chargeback reason codes?

Undoubtedly, we need to know the chargeback codes to win the chargeback. Each chargeback is associated with a particular reason and knowing it is essential to organize required documents and resolve the dispute in your favor.
