Demande d'ouverture des droits pour passport talent- Famillie

Hello, I have recently moved to Grenoble from Belgium to join with my husband, I have a passport talent - Famille. I would like to create my account, and require the social security number. I would like to inquire the question below:

• Can I send the request form to CPAM in Grenoble to create my social security number?

• Can I use my Belgium number linked to my social security number or I have to use a France number?

Thank you in advance.
