Official definition

Specification of the debtor’s account or unique identification needed for reasons of regulatory requirements is insufficient or missing

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 debtor's account or identification required by regulation is missing or insufficient. Regulations on payer information in transfers require it for most cross-border payments.

What to do

  • Add the debtor account (IBAN or other identifier) or a unique identification, then send a new payment.
