Official definition

Payment is a duplicate of another payment.

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 payment is a duplicate of another payment. As a cancellation reason it asks the receiver to stop or send back the second copy.

What to do

  • Make sure only one payment remains. Use the UETR of the duplicate when you ask for cancellation, so the receiver can find it.
