Registering for Social Security Number

Hi, I am asking on behalf of my brother he is an aspiring actor from the UK who has secured himself an agent in Paris and who wishes to cast him in some projects. She said he needs to get himself a social security number first though.

He is moving to Paris to work, effectively self-employed how does he go about registering online for the social security number? I can’t even find the right site that he needs to visit. What documentation does he also need to provide?

Many Thanks, apologies if an obvious question but I have been reading everything I can find on the topic but not the answer I am looking for!

Hi - you can’t register online for a social security number.

Take a look at this link - specifically the second section Attribution et Utilisation (Attribution and Use) and use this as your staring point.
