ISO 20022 definition
Party who initiated the message is not recognised by the end customer.
Typical cause
In SEPA operator usage this most commonly reflects an incorrect or unregistered Creditor Identifier — the Creditor ID in the collection message does not match a registered creditor. A common failure during new SDD program setup.
What to do about it
Verify your Creditor Identifier registration with your national competent authority/scheme, and confirm the correct Creditor ID is populated in every collection message before resubmitting.
The article covers BE05 in prose rather than in the SDD table — it is grouped under agent/party-identification failures in ISO 20022 external code sets rather than the AG/FF table grouping. Confidence is medium relative to the table-sourced codes above.
