Mentions Légales Scraper: SIREN, TVA & Emails, French Websites

What does Mentions Légales Scraper do?

Mentions Légales Scraper reads the legal notice (mentions légales) of French company websites and returns who runs each site: the company name and legal form, its SIREN (or SIRET), the RCS registry town, its TVA intracommunautaire number, the registered address — and the emails and phone numbers on the same pages. One record per website.

French law makes every site name the company behind it, and also the company that hosts it (OVH, o2switch...), often the agency that built it, sometimes a lender or a parent group. This Actor keeps the company's own numbers and leaves the others out, and it checks every number: a SIREN by its Luhn key, a TVA number by its key — a misprinted number is not returned as one. You pay only per company with an email of its own.

Why use it?

• French B2B leads with the company data a CRM needs: SIREN, TVA, address, an email to write to.
• KYB and data cleaning: match a list of websites to registry numbers before an API lookup.
• No registry login, no scraping of company directories: the data comes from the company's own website.

How to use it

1. Open the Input tab and paste the websites (domains or URLs), upload a text or CSV file, or link a Google Sheet.
2. Click Start.
3. Download the results as JSON, CSV, Excel or HTML from the Output tab.

Field	Meaning
company.register_number	SIREN (9 digits) or SIRET, Luhn-checked; register_court the RCS town.
company.vat_id	TVA intracommunautaire, its key checked against the SIREN.
company.company, legal_form, address	As the notice prints them for the company itself.
company.representatives	People under a representation label; the directeur de la publication is not one.
emails, best_email, phones	The contacts on the same pages, emails MX-checked.

Accuracy

Measured on random French domains from the Tranco list, labelled by reading each page before the extractor was run on them (the second blind draw, the number to quote):

Field	Right	Wrong	Missed
SIREN / SIRET	5	0	1
TVA number	5	0	1
Company name	3	0	5
Postcode	2	0	5

The numbers are the product; the company name is the weak field — a notice that names the company only in a sentence the extractor does not recognise gives none. Across the four countries of the draw, 27 company numbers were right, 1 wrong and 5 missed.

How much does it cost?

$0.0045 per company with an email — on its own domain, or a personal mailbox it uses, accepting mail — on the Free and Starter plans; 10% less on Scale, 20% less from Business up. A site without one is returned and costs nothing. 1,000 companies cost $4.50.
