When you become insured « assuré social » you receive a « carte vitale ». This card looks like a credit card, is green, and on the new ones, have a photo.
On this card, the name of the « assuré » is written and his social security number « numéro d'immatriculation ». It's a long number which identifies you (15 numbers).
If you have a family, there may be only one « carte vitale » because the person who is « assuré » has taxes taken out of his paycheck. If you're a couple and both of you work, each one has his or her own « carte vitale ». If you have children, then you must choose on which « carte vitale » you register your children.
The person holding a « carte vitale » in his name is the « assuré », and those who are covered by his card (spouse, children) are the « ayant droit » legally speaking.
To become an « ayant-droit » (you, your spouse or children) you must fill in out a special form and send it to your centre de paiement.
