A Reference ID, often referred to as a Transaction Reference Number (TRN) or simply Reference Number, is a unique combination of letters, numbers, or both that serves as a distinctive identifier for a specific transaction or record. It is typically generated by the system, organization, or platform conducting the transaction and is provided to the user for reference and tracking purposes.
