If you don’t mind answering another question on this subject: do you know which organism attributes the autoentrepreneur with a social security number, and how?
Presumably the Régime Social des Indépendents is responsible, but they aren’t eager to tell you what to do to obtain a SS number.
I’ve been through autoentrepreneur.fr, and they don’t seem to know either. Nor is it in the French guide.
Thanks in advance, Andy
