Which legal entity corresponds to the trading name ?
- Start with a stable identifier and jurisdiction; distinguish brand, establishment and company.
- Consult the primary register and relevant documents, retaining their dates.
- Compare addresses, roles, status and notices without conflating namesakes or subsidiaries.
- Confirm the contact and transaction through an official channel independent of the received message.
What the method cannot establish alone
Administrative existence guarantees neither solvency nor contact authenticity. Distinguish filed declarations from verified facts.

Questions about tools and external searches
Where are search results displayed?
On the selected provider’s website, in a new tab. IIS does not retrieve, host or display investigation results. Directory filters only filter the editorial catalogue.
Is the typed query stored?
The launchpad builds links inside your browser, without sending the query to IIS or storing it in browser storage. Clicking a prepared link sends the query to the named provider, under its own rules.
Are all tools free and available in every language?
No. Access may require an account, subscription, software or quota. The catalogue is available in French and English; providers set their interface languages, coverage and conditions.
Does no result prove that a fact is false?
No. Index coverage, spelling, language, access limits and capture dates can explain a missing result. Record what was searched and what remains unknown.
