Find a director's email from the SIREN or SIRET number of a French company
The French company register does not publish directors' email addresses. A SIREN number does give you the company and its legal representatives: what remains is to find the mail domain and the address format, then verify each address before you write.

The short answer
No, there is no official file that links a SIREN number to a director's email. Yes, you can get there in four steps: the company, its directors, the address format, the verification. By hand it is slow and repetitive. Veriphee chains the four steps from the number alone, in about 90 seconds.
SIREN or SIRET: which one to use
| Number | Length | What it identifies | For finding a director |
|---|---|---|---|
| SIREN | 9 digits | The company (the legal entity) | The right number: directors are attached to the company |
| SIRET | 14 digits | One establishment of the company (SIREN + 5 digits) | Works too: the first 9 digits are the SIREN |
A French intra-community VAT number also contains the SIREN: it is its last 9 digits.
What the register gives you, and what it does not
- It gives: the legal name, the head office address, the activity code, the creation date and the legal representatives (président, gérant, directeur général).
- It does not give: email addresses, direct phone numbers, or decision-makers who are not company officers (CFO, sales director, HR director).
- Mind the dates: a director listed in the register may have left recently. A dated source is worth more than an undated name.
The four steps, from number to address
- The company. The number is resolved in the register: you get the exact name, which avoids namesakes.
- The directors. Legal representatives first, then the roles that matter for your offer. See finding a director's email.
- The address format. A company generally applies a single convention (firstname.lastname@, f.lastname@, and so on). See company email address format.
- The verification. A constructed address is only a guess until it has been checked. See verifying an address without sending a message and the case of catch-all domains.
You have a list of SIREN numbers
This is the most common case: a register export, a purchased file, a trade show exhibitor list or the companies that visited your website. In Veriphee you paste up to 50 numbers (or import a CSV file) and each company becomes a record: directors, addresses, verdict. One credit covers a whole company, and half the credit is returned if no valid address is found.
Limits to keep in mind
- The method applies to companies registered in France.
- A very small business sometimes has no website and no domain of its own: the director then uses a personal address, which Veriphee does not look for.
- On a catch-all domain, verification alone cannot decide: the address is marked "To confirm".
- The legal framework is that of business-to-business prospecting: a message related to the person's role, a clearly identified sender, and the right to object respected.
Frequently asked questions
- Can you get a director's email directly from a SIREN number?
- Not from the official register, which does not publish email addresses. The SIREN identifies the company and its legal representatives; the address is then built from the format the company uses, and verified.
- Does a SIRET number work too?
- Yes. The first 9 digits of a SIRET are the company's SIREN. Veriphee accepts the name, the SIREN or the SIRET.
- How much does it cost to enrich a file of SIREN numbers?
- With Veriphee, one credit per company, directors and verification included: at decreasing prices, from €2.50 down to €0.77 excl. VAT per search depending on the pack (€93 excl. VAT for 100, for example). These are credit purchases, with no subscription. Two searches are free when you sign up.
- Is it GDPR compliant?
- Business-to-business prospecting is allowed on the basis of legitimate interest, provided the message relates to the person's role and they can object easily. Veriphee only processes professional data.
