Understand the evidence behind each check
See where the data comes from, how to interpret a match and how submitted documents are handled.
Where the data comes from
- Invoices
- National Tax Agency qualified-invoice registry for issuer registration.
- Companies
- National Tax Agency Corporate Number data for registered names and addresses. Company reports can add public filings and other sources where available.
- Addresses
- Japan Post for postal-code evidence when supplied and romanization; geocoder evidence indicates the level matched.
Each registry response states its source and the as-of date of the snapshot it was checked against.
How to read a result
- Match
- The fields being compared agree. A matching T-number does not establish that an English issuer name matches. Check whether the English name is official, sourced elsewhere or romanized.
- Needs review
- A field differs or the available evidence supports only a partial or ambiguous match.
- No record or unavailable source
- Check the input when no record was found. A source failure means the lookup could not be completed.
It is a public-registry pre-check with explicit review signals — not KYB, AML or sanctions screening, and not legal or tax advice.
How documents are handled
