An ARN is an acquirer reference number. It's a number that both Visa and Mastercard assign to refunded transactions.

Visa ARNs can be used to sign up for RDR. 

To find a Visa ARN, go to your processor portal and filter your transactions by "refunded". If possible, filter down additionally by Visa transactions and transactions refunded over 3 days ago. 

Once you've located a Visa transaction refunded 3+ days ago, you should be able to find an ARN number somewhere on this transaction page. 

With certain processing portals, you may not be able to view the ARN within your online portal. In this case, we'd recommend contacting your processor and asking for 2-3 Visa ARNs.

It may take up to 5 days after a refund has been processed for the Visa ARN number to appear.

All Visa ARNs start with either a 2 or a 7 and are 23 digits.

If you do not have any refunded Visa transactions yet, we recommend placing a test transaction using your own Visa card. 

After 3 days, refund this test charge. If you do not wait 3 days, the refund will be processed as a reversal, meaning the ARN will never show up. 

Approximately 2-4 days after this refund has been processed, a Visa ARN will show up. If it does not show up, you can contact your processor to get this ARN number. 

Please send us this ARN number once it shows up.

As always, let us know if you have any questions!
