Hello Sultan,
Unfortunately, because of some safety and confidentiality issues, we can’t reach any of your information or file from this forum.
If you haven't received a letter from your CPAM office ( caisse primaire d'assurance maladie) in order to let you know your social security number. You can contact the CPAM’s English speaking line. Dial 09 74 75 36 46.
Your Advisor will ask you to confirm the four last digits of your Iban number. it's better to have a RIB ( relevé d'identité bancaire) with you.
Have a nice day.
