SIRENE: the French business registry as data
SIRENE is the French business registry kept by INSEE, the national statistics office: every company gets a SIREN number, every establishment a SIRET. Reachable imports the full SIRENE file every month and its updates every day. You get columns (identity, NAF code, headcount, establishments) and a signal: new company filings.

What is the SIRENE connector?
The SIRENE connector gives the official identity of every French company, as INSEE publishes it. SIREN is the company's 9-digit number; SIRET, 14 digits, identifies one of its establishments.

| Licence | Licence Ouverte (Etalab open licence) |
| Coverage | Every company and establishment registered in France, active and closed |
| Refresh at Reachable | Stock file every month, daily updates through the Sirene API; the last collection date is shown on the connectors hub |
| History | Closed companies kept, with their closing date |
| Price of a run | Shown on pricing and on the hub, read from the current price grid |
What SIRENE data do you get?
The connector exposes two columns and one row source. Every value carries its source (SIRENE) and its update date.
| Column | Fields |
|---|---|
| Company record | name, status (active or closed), legal form, NAF code, size category (SME, mid-cap, large), headcount band and its year, employer or not, social economy, creation date, closing date, head-office SIRET, town and département, open establishments |
| Creation or new establishment | creation date, open and total establishments, latest establishment opened (SIRET, date, head office or not, town) |
| "France database" source | the companies matching your filter (area, NAF code, creation date…), as the rows of a list |
Real sample: six companies created in late October 2026 in Alpes-Maritimes (Nice area), as Reachable's public API returns them (data as of 12 November 2026, source INSEE SIRENE).

Which prospecting signals does SIRENE give?
The main signal is a new company: a business that has just been created needs to buy everything. A list filtered on an area and a NAF code, re-run every week, adds the companies created since the previous run.
- New company: accountant, bank, insurance, website, equipment. The need is born with the company.
- New establishment: an existing company opens a site; it hires, equips and looks for local suppliers.
- Change of activity or headcount: a headcount band going up flags a growing company.
- Closure: remove it from your files before sending anything.
How many companies were created in October 2026?
The eight départements below recorded 32,747 new companies in October 2026, including 11,416 in Paris, according to our SIRENE database (computed on 12 November 2026).
| Département | New companies, October 2026 |
|---|---|
| Paris (75) | 11,416 |
| Rhône (69, Lyon) | 3,771 |
| Bouches-du-Rhône (13, Marseille) | 3,655 |
| Nord (59, Lille) | 3,191 |
| Gironde (33, Bordeaux) | 3,068 |
| Haute-Garonne (31, Toulouse) | 2,642 |
| Alpes-Maritimes (06, Nice) | 2,633 |
| Hérault (34, Montpellier) | 2,371 |
Method: companies (legal units) whose SIRENE creation date falls between 1 and 31 October 2026 inclusive, head office in the département, all legal forms, sole traders included. The count is read from Reachable's public API (/v1/public/companies/new) as the difference between companies created since 1 October and those created since 1 November, so creation dates after the day of the computation are excluded. These figures will still rise: a creation is often registered several weeks after its date.
Which connectors should you combine with SIRENE?
SIRENE tells you who exists; the other connectors tell you who needs you. Three recipes:
- New companies + Google Maps: restaurants created this month in a département, then their Google listing (rating, reviews, website). A listing without a website is a lead for a web agency.
- New companies + website: new consulting firms, then an analysis of their website (missing, slow, no legal notice).
- Company record + BODACC: your customer file, matched to SIREN, then legal notices (insolvency, business sale) to rule out companies in trouble.
Every connector and its price per run are on the connectors hub.
How do you use it from an AI agent (MCP)?
Your agent (Claude, ChatGPT, Cursor) queries SIRENE in plain language through Reachable's MCP server. Example request:
List the companies created since 1 October in Alpes-Maritimes with a NAF code starting with 62, with their town and creation date.
The agent returns a table: SIREN, name (unless disclosure is restricted), NAF code, town, creation date, each row with its SIRENE source and update date. It can then turn it into a list re-run every week.
What are the limits of SIRENE?
SIRENE tells you a company exists, not that it is reachable or actually trading.
- Delay: a new company shows up a few days to a few weeks after it is declared. The count for a recent month therefore keeps growing for several weeks.
- Restricted disclosure: some sole traders refuse to have their name and address published. These companies stay in your lists, without name or address.
- Headcount: the headcount band is self-declared and can be several years old; its year is provided.
- Directors: SIRENE does not list them. They come from the RNE (INPI), not imported yet.
- Matching: a row from a CSV or Google Maps is matched to a SIREN with a method and a confidence score; below your list's threshold (0.95 by default), SIRENE columns do not run. The method is on the methodology page.
