I have a microentreprise and was wondering if it's normal to keep the same SIRET and SIREN number if you add additional actvities to your main one. You don't get one per activity?
Specifically as those activities are all different.
Also, where can I get a confirmation/certificat d'inscription from INSEE with all my activities listed on a page. I didn't receive anything like that after adding the activities with the URSSAF.
Thanks for your help!
