This is a very common question, and totally understandable! When launching a business, everyone talks about the famous Kbis, but if you’re registering as a micro-entrepreneur, the answer is: not always. Don’t worry: here’s a clear explanation 👇
📌 What’s the difference between a SIREN and a Kbis ?
🆔 SIREN | 📄 Kbis Extract |
9-digit unique ID number | Official company registration certificate |
Assigned by INSEE (French stats office) | Issued by the commercial court (RCS) |
Mandatory for all businesses | Only for commercial companies |
Used for invoices, taxes, contracts | Acts as a legal ID for companies |
In short:
✔️ Every business gets a SIREN
📄 A Kbis only applies to certain business types or activities
🤔 As a micro-entrepreneur, will I receive a Kbis?
It depends on your activity. Here’s the breakdown:
✅ You’ll get a Kbis if:
Your main activity is commercial
You’re registered with the RCS (Trade & Companies Register)
Example: online shops, resellers, product sales
❌ You won’t get a Kbis if:
You have an artisanal activity →
You have a liberal activity (consulting, coaching, design, writing, etc.) → No Kbis, just your INSEE registration with SIREN/SIRET
Example: freelance consultant, developer, writer, therapist
💡 No Kbis? Don’t worry — it’s not a problem
It’s 100% fine to not receive a Kbis.
Your SIREN or SIRET number is enough to:
Invoice clients
Register on platforms and marketplaces
Open a business bank account
Prove you’re a legal business in France
🧾 You also receive an INSEE certificate, which is official proof of registration.
📌 Only certain clients or public tenders require a Kbis, and only if your activity is registered as commercial.
📬 Summary
Business Type | Document You Receive | Notes |
Commercial | ✅ SIREN + ✅ Kbis | Registered with RCS |
Artisan | ✅ SIREN | Registered with Chamber of Trades (CMA) |
Liberal | ✅ SIREN only | No RCS or CMA registration |
