Official definition

Account specified is blocked, prohibiting posting of transactions against it.

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.

The account is open but blocked, so the bank cannot post to it. Blocks come from court orders, sanctions, fraud checks, a deceased holder or the bank's own decision. The code does not say which.

What to do

  • Do not resend to the same account straight away; it will be blocked again.
  • Contact the beneficiary through your usual channel and ask them to resolve the block with their bank, or to give other account details.
