Definition

The transaction reference number, often listed as "Trans Ref No", reconciliation ID, or TRN, is a unique identifier that our transaction servers generate for each payment service request (e.g., credit card capture request) you submit. It is then provided back to you in the service response data, and for most processors it is included in the transaction data sent to the payment processor.

Sharing of the transaction reference number between your acquiring bank, the payment processor, your customer's card-issuing bank, and payment gateway allows all four parties to identify the same transaction with this number. Use the transaction reference number with your acquiring bank or advise your customer to reference it when contacting their card-issuing bank to seek assistance with the inquiries such as:

• Confirming funds transfer status.
• Investigating declines or error responses.
