What Is a STAN or ARN Number?
A STAN (System Trace Audit Number) and ARN (Acquirer Reference Number) are unique reference numbers used by payment processors and gateways to track and trace a payment transaction.
These numbers can help payment processors locate a specific charge, authorization, refund, or other transaction as it moves through the payment processing system.
A single payment may pass through several stages before the transaction is fully processed and the funds are received by the merchant. The STAN or ARN helps the payment processor trace the transaction across these stages.
STAN vs. ARN
STAN (System Trace Audit Number): A transaction reference number generated by a payment system to help identify and trace a transaction.
ARN (Acquirer Reference Number): A unique reference number used by the card payment network and acquiring bank to trace a card transaction, particularly when tracking payments, refunds, or disputes.
The exact reference number available depends on the payment processor or gateway being used.
Where Can I Find the STAN or ARN Number?
STAN and ARN numbers are available only through your payment processor or payment gateway. ChargeAutomation does not receive or have access to these reference numbers.
To find the number:
Log in to your payment processor or gateway account.
Search for the relevant transaction.
Open the transaction details.
Look for the STAN, ARN, or transaction reference number.
If you cannot find the number, contact your payment processor or gateway's support team and provide them with the relevant transaction details.
Important
ChargeAutomation Support cannot retrieve or provide the STAN or ARN number because these details are not available in ChargeAutomation's system. You will need to contact your payment processor or gateway directly for assistance.
