RR04 (RegulatoryReason) is an ISO 20022 ExternalReturnReason code used in pacs.002 / MT103 STP rejection messages on the SWIFT network. Rejection driven by regulatory requirements.
Details
Why it happens: Sanctions list match, OFAC/EU/UN block, country embargo, or local FX-control rule.
How to fix it: Cannot proceed with this beneficiary or corridor; consult your bank's compliance team.
When a bank rejects a SWIFT payment with RR04, you usually receive the code along with an MT103-STP, MT n96, or pacs.002 message. Your bank may relay the code to you with a plain-English explanation. If they don't, paste your UETR into the Ohmyfin tracker — the rejection status will show in the SWIFT GPI feed.
RR04 is part of the global ExternalReturnReason1Code code set maintained by ISO 20022. The same code is used by SWIFT, SEPA, FedNow, TARGET2 and most modern payment rails worldwide.

Frequently asked questions
What does SWIFT reject code RR04 mean?
Rejection driven by regulatory requirements.
How do I fix a RR04 rejection?
Cannot proceed with this beneficiary or corridor; consult your bank's compliance team.
Will I get my money back after a RR04 rejection?
Yes. SWIFT rejections automatically return the funds to the originator's account, usually within 1–5 business days. Some banks credit immediately; others wait for the actual return wire.
Can I re-send the same payment after RR04?
Yes — once you fix the underlying issue, you can re-send with a new UETR. Do NOT re-send with the same UETR; that triggers AM05 (Duplication).
