How do I look up a company by its registration number in France?
Enter the SIREN to look up a France company directly on Infogreffe. Unlike a name search, an SIREN returns exactly one entity, which is why it is the identifier to use for KYC, invoicing and contract checks.
Step-by-step
- 1
Find the SIREN on the paperwork
The SIREN normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.
- 2
Search the SIREN
Enter the number exactly as printed. Punctuation and spacing vary between documents — strip them if the search returns nothing.
- 3
Confirm the returned entity
Check the legal name on the returned record matches the name on your paperwork. A mismatch between quoted number and quoted name is a serious warning sign.
