Hi Jo-Ann. I moved here with my husband a month ago and are setting up our small chambre d'hotes business. I am registering as a micro-entrepreneur. I had managed to complete the on line forms via the URSSAF website. I then received an email telling me that my activity is commercial and since 01/01/2016, commercial creations must be made â€‹â€‹on the business counter Site http://www.guichet-entreprises.fr/ or at a Chamber of Commerce. I have attempted the on line forms at both sites only to find i need a social security number which it wont let me complete the forms without. I had understood that when i registered as an micro-entrepreneur, that is when i would receive one? Am i using the wrong sites or forms or is there a step I have missed. Could you advise? Many thanks.
