1. ARN FAQs
1A. Can I Use ARNs That Start With 8?
No. All ARNs must begin with a 2 or 7.
ARNs that begin with 8 belong to Mastercard transactions. RDR supports Visa transactions only, so Mastercard ARNs are not valid.
If you attempt to add an ARN beginning with 8, you will see an error stating the ARN cannot be added.
1B. How long until an ARN appears after a refund?
ARNs typically appear within 24–48 hours.
If you do not see ARNs after that window, contact your processor for help.
1C. Can I Use Old ARNs?
All ARNs must be from transactions within 90 days.
1D. Will Partially Refunded Transactions Provide ARNs?
Yes, if an order is partially refunded, it will provide an ARN.
2. Descriptor FAQs
2A. Why Can't I Add My Descriptor?
It may be linked to another account in our system. Contact support for help.
It may already be enrolled with another chargeback alerts provider.
You will receive an email with steps to request a release of the descriptor and/or BINs and CAID from that provider.
2B. How Do I Remove Descriptors & ARNs?
You cannot remove them yourself due to our integrations with Ethoca and Verifi.
Follow these points to unenroll (remove) your descriptor and/or ARNs:
Billing descriptors:
(Fastest) Submit the unenrollment form.
Or contact support to unenroll them.
ARNs: Contact support to remove them.
ℹ️ Removing ARNs does not change alert coverage or false-alert behavior.
2C. How Do I Add More Billing Descriptors?
Go to Alerts in the left sidebar.
Open Configure from the dropdown.
Select the alert network and click
+ Enroll More Descriptors.If you do not need to add another integration, click
Continue.
Enter the descriptor(s) and click
Continue.Wait for activation.
During this process, descriptors link to the alert network (RDR, CDRN, Ethoca), not to integrations.
See this guide for the time it takes to activate under different networks.
2E. Why Can't I Add More Descriptor(s) to RDR If I Signed Up Using my BIN and CAID?
Accounts enrolled in RDR using an acquiring BIN(s) and CAID cannot add descriptors themselves yet. We are working on a fix.
Contact our support and tell them:
Hello. I signed up for RDR using my BIN and CAID. I would like to add [add descriptor(s) here] to my account.
