On the URSSAF form declaration trimestrielle de recette, I have an numéro national d’Identité number (NNI). I also have a securite sociale number. The first 5 digits of these numbers are similar but not the remaining numbers. What is the difference in these numbers and which must I use when dealing with caisse régionale d’assurance maladie (CRAM)?
