What does the chargeback reference number signify?

The chargeback reference number is significant because it serves as an issuer-assigned identifier that helps track and manage the details associated with an outgoing chargeback. This number is crucial for reconciliation and facilitates communication between parties involved in the chargeback process. By having a unique reference associated with each specific chargeback, it allows financial institutions to efficiently access relevant transaction information, follow up on disputes, and monitor the status of the chargeback.

In the context of chargebacks, the reference number is not simply about identifying a transaction in general, which may apply to various types of identifiers, nor does it pertain to the reason behind the chargeback itself. It also does not relate to successful transactions, as chargeback reference numbers specifically pertain to disputed or reversed transactions rather than completed ones. Thus, the issuer-assigned characterization is what makes this reference number distinct and vital for the chargeback process.
