No Mandate

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

What it means in practice

In a pacs.002 or pain.002 status report, a status reason code explains why a payment instruction was rejected (RJCT) or why it has another status. It sits in TxInfAndSts/StsRsnInf/Rsn/Cd.

There is no valid mandate for the direct debit, or the mandate data in the collection does not match what the debtor bank holds.

What to do

  • Check the mandate reference and signature date with the debtor, and do not collect again until the mandate is in place.
