Official definition

Party who initiated the message is not recognised by the end customer

Definition from the ISO 20022 External Code Sets, 2Q2026 (published 28 Aug 2026).

What it means in practice

In a pacs.004 payment return, a return reason code explains why funds that were already settled are being sent back. It sits in TxInf/RtrRsnInf/Rsn/Cd, and bank statements (camt.053, camt.054) repeat it in RtrInf/Rsn/Cd.

The end customer does not recognise the party that initiated the payment or direct debit. You see it mostly with direct debits the debtor did not expect.

What to do

  • Check the creditor identifier and mandate details, and contact the debtor to confirm they agreed to the collection.
