VAT Validation
Zeno extracts VAT IDs from documents and evaluates validation state for review.
Validation states
You may see one of these outcomes:
- Valid: VAT is confirmed by validation source
- Not determined: VAT could not be conclusively verified in current flow
- Unknown: temporary lookup/service uncertainty
Not determined does not automatically block document registration.
Where state is shown
- document preview badges,
- mandatory fields summary,
- registry-level VAT columns.
Why status can be non-final
Common reasons:
- lookup is disabled by policy/feature flag,
- external VAT service is temporarily unavailable,
- extracted VAT format is incomplete/noisy,
- source document lacks enough context.
Operator guidance
- Verify VAT text in original document
- Correct field manually if OCR/parser captured it incorrectly
- Continue review and decide whether to register based on your compliance policy
Important notes
- VAT status is a compliance signal, not legal advice
- Zeno does not silently alter VAT source values
- Final acceptance remains a user decision
