FAQ : Registration - Social security number

What is a social security number?

A NIR (national membership registry number), commonly referred to as a social security number, is a unique 15-digit identification number. INSEE (France’s National Institute of Statistics and Economic Studies) automatically assigns one to each person born in metropolitan France and in France’s overseas departments (DOM).

This number appears on the French health insurance card (“Carte Vitale”) and expedites the holder’s access to Social Security and medical services.
