You both have to make an application…one for each of you. Did you make 2 applications or just for your husband, thinking that you would be added to his. Under the new regime, you both have your own CV and therefore need to make separate applications.
If you did make separate applications, maybe yours is just slow to come to you. Mine came a few days before my wife’s. First you receive an Interim Attestation (with a temporary number) then you provide them with details of your doctor and photos of yourself. After this the final attestation and then the actual Carte Vitale will be sent to you.
Under PUMA we sent our applications direct in the mail and they all go to the CPAM in Bayonne from recollection, not necessarily your local CPAM office.
