How to get your French Social Security Number (Guide for Foreign Workers)
If you’re moving to France for a job, welcome! Whether you're relocating for a short-term contract, an internship, or a long-term career, one of the first steps you’ll need to take is to get your French social security number.
This guide explains what the number is, why it’s essential, and how to get it step-by-step.
What is the French Social Security Number?
The French “numéro de sécurité sociale” is a unique 15-digit identification number used by the French social security system. It gives you access to healthcare, social benefits, and ensures your employer can pay contributions on your behalf.
It’s often requested when:
Starting a job or internship
Visiting a doctor or hospital
Getting reimbursed for healthcare costs
Opening a bank account
Applying for housing assistance
Registering for maternity/paternity leave or unemployment benefits
If you're working and living in France, and you don’t already have a French social security number, you need to apply. This applies to:
EU/EEA citizens
Non-EU nationals with a work permit
Students doing paid internships or work-study programs
How to get your French social security number
Option 1: Your employer handles it
In many cases, especially if you're on a permanent or fixed-term contract (CDI or CDD), your employer will register you with the French social security system. They submit your first “déclaration préalable à l’embauche” (DPAE), and you’ll receive your number by post within a few weeks.
Ask your HR contact to confirm if they’ve submitted this.
Option 2: You apply yourself (especially as a student, intern or freelancer)
You can apply manually by sending a file to your local CPAM(Caisse Primaire d’Assurance Maladie). Here's what to do:
What documents do I need?
You’ll need to prepare and send:
A completed application form (usually the "Demande d’ouverture des droits à l’assurance maladie")
A valid ID or passport
Birth certificate (with translation if not in French)
Proof of residence in France (e.g., rental contract, utility bill)
Employment contract or internship agreement
RIB (French bank details for reimbursement)
Optional but recommended:
Your visa or residence permit if applicable
Where to send your file?
Send all documents (copies only) by post to the CPAM office corresponding to your place of residence. You can find the address on the official Ameli website.
How long does it take?
It can take 4–8 weeks to receive your temporary number (called “numéro provisoire”). This allows you to access healthcare and claim reimbursements.
The final number (permanent) may follow later, along with your Carte Vitale (the green health insurance card used in France).
Can I access healthcare while waiting?
Yes! As soon as you receive your temporary number, you're covered under the PUMA (Protection Universelle Maladie) and can be reimbursed for healthcare expenses.
FAQ – Quick Answers
Can I apply for a social security number before arriving in France? No, you must be physically present and provide a French address.
Do I need a French bank account? Yes, to receive reimbursements, you'll need to provide a French RIB (bank details).
What if I already had a number from a previous stay? If you’ve worked or studied in France before, your number remains valid for life. You can reactivate your rights by contacting the CPAM.
Can I apply online? Only in some cases. Most first-time applicants still need to send documents by post.
Getting your French social security number is one of the most important steps to settle in smoothly. Don’t hesitate to ask your employer or CPAM for help.
