What Discover Reason Code RN Means
Discover reason code RN, Credit Not Received, is filed when a cardholder claims a promised or expected refund never appeared on their account. This consumer dispute code applies when a merchant acknowledged a return or issued a credit but the funds did not post.
The central question is whether the credit was actually issued and settled through the network. A credit entered in your POS system but never submitted for settlement is invisible to the cardholder.
RN applies when a credit was expected but not received. RM covers recurring charges the cardholder canceled. If the cardholder is disputing an unauthorized charge rather than a missing refund, a different code applies.

Common Trigger Scenarios
- Refund issued but not settled. Credit entered in the POS but never submitted for settlement through the processor. The cardholder never sees the funds.
- Credit applied to wrong account. The refund was processed but applied to a different card or account than the one used for the purchase.
- Posting delay dispute. Credits take 3–5 business days to post. Cardholders sometimes file disputes before the credit appears.
- Partial refund disputed. The merchant issued a partial credit; the cardholder expected a full refund and disputes the difference.
- Verbal promise not fulfilled. Staff told the cardholder a refund was coming but no credit was ever processed.

Evidence You Will Need
- Credit memo or refund confirmation — documentation showing the credit was issued: date, amount, and reference number
- Settlement record — proof the credit was submitted for settlement and cleared through the network
- Return authorization — if the credit followed a return, the RA number and date
- Cardholder communication — any emails confirming the refund was initiated
- Refund policy — if no credit is owed, your policy showing the terms the cardholder agreed to

- Credit issued but not settled. Approving a return in your CRM without submitting the credit for settlement through your processor is the most common RN failure mode.
- No documentation. Saying “we issued a refund” without records showing date, amount, and reference number gives Discover nothing to verify.
- Credit to wrong account. If the credit went to a different card, you must show where it went and correct the error.
- No response. An unanswered RN is an automatic loss. Even if the credit is in transit, respond with the pending credit reference number.

- Confirm credit status before responding — was it issued, settled, and applied to the correct account?
- If credit was issued: present the settlement record, credit memo, and processing confirmation.
- If credit is pending: provide the reference number and expected posting date.
- If no credit is owed: cite the refund policy and show the cardholder’s acceptance.
Prevention Tips
- Process credits same day. Same-day credit submission eliminates the gap between approval and posting that triggers most RN disputes.
- Send refund confirmation emails. A confirmation with reference number and expected timing gives the cardholder visibility and reduces premature disputes.
- Reconcile refunds daily. A daily check that all issued credits were settled catches failures before cardholders notice.
- Train staff on approved vs. processed. Approving a return is not the same as submitting a credit for settlement.

What if the credit is still processing when I receive the RN dispute?
Respond immediately with the credit reference number and expected posting date. A pending credit with documentation is a valid response.
