Cancellation requested by the Debtor

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 ordering customer asked for the payment to be cancelled. This is the usual reason in a camt.056 sent on a customer's request.

What to do

  • The receiving bank decides whether it can still stop or return the funds; follow up on the camt.029 answer. Many banks need the beneficiary's consent once the funds are credited.
