SIREN
The company's number
Nine digits issued by INSEE, unique and permanent. The right key to deduplicate a prospect list.
Who is this company, according to the register?
Type a name, a SIREN or a SIRET. The tool shows what the official French register publishes: identifiers, activity, head office, creation date, size and leaders.
01What it shows
The official record, without signing up.
Before writing to a French company, check that it is active, what it says it does and who runs it. All of it is public.
SIRET
An establishment's number
Fourteen digits: the SIREN plus the establishment's own number. The tool shows the head office's and how many establishments are open.
NAF
The declared main activity
The company's activity code and its official label. It describes the declared activity, not always the exact trade.
Leaders
As listed in the register
The leaders and their roles as the register publishes them. Companies that opted out of publication are never shown.

02Questions
What people ask.
What is the difference between SIREN and SIRET?
The SIREN (9 digits) identifies the company. The SIRET (14 digits) identifies one establishment: the SIREN followed by a 5-digit internal number. A company has one SIREN and as many SIRETs as establishments.
Where does the data come from?
From the French State's company search API, which publishes INSEE's SIRENE data and the national company register. The “Official sheet” link opens the company's page on annuaire-entreprises.data.gouv.fr.
Why is there no email or phone number?
The register has none. A company's address is usually on its own website, on the contact or legal notice page, and should be verified before you send anything.
Why can't I find a company?
Either the name you typed differs from the registered name (try the SIREN), or the company opted out of publication: it is then never shown here, nor used by Mailbase.
Are my searches stored?
No. The tool queries the public register and returns the answer without recording anything. Searches are rate-limited per minute to prevent abuse.
