41 codes that cover most of what an originator sees. Each one carries the decision: retry or stop, how long the receiving institution has to send it, what the guidance rests on, and when it was last checked.
What the tier labels mean, and how far this page has been checked
Draft
An agent wrote it from published material and nobody has checked it. Use it as a lead to confirm, never on its own as the basis for a retry, a return, a deadline or a compliance decision.
Corroborated
A validator found the same answer in one or more named public sources; the class in brackets says how strong they are. "Secondary sources only" means bank, processor or industry guides and nothing from the operator or regulator. Corroborated does not mean checked against the governing rulebook, so confirm before you act.
Verified
A person checked it against SIX Interbank Clearing (Swiss Payment Standards)'s own current text and recorded the edition and date. The strongest tier here, and still reference material, not legal or compliance advice.
On a rail fact, every detail line names the section or instrument it rests on and whether that is a rule, a law, operator guidance, or observed practice.
Nothing matches. Try a code number, or a phrase like "revoked", "savings", or "company name".
Known gaps in this build
Not yet covered: NARR, the code a Swiss bank uses for its own free-text status reason, has no record here; institution-specific proprietary codes that a bank may send in the Proprietary element are not covered, and no bank's list has been read; the ISO 20022 external code set was refused to a plain request, so whether ISO has registered every CH code is not established; each bank's own processing rules, cut-off times and duplicate-check periods sit outside the Swiss Payment Standards and are not covered; the interbank SIC and SIC IP reason codes are a separate family and are not in this directory.
