ISO 20022 definition
Bank Operation code specified in the message is not valid for receiver.
Typical cause
Message structure error — the local instrument code or bank operation code in the collection is invalid for the receiving bank.
What to do about it
Validate message construction against ISO 20022 SDD schema requirements before resubmission; a processing-stage error the acquirer/gateway typically resolves.
Rulebook note
From October 2025, collections with non-compliant structured-address formats may return RR02 or RR03 instead of AG02 — check both if you see a rise in either.
Confidence: high.
