On the basis of the data in the pre-employment declaration sent to it by the body referred to in Article R. 1221-3, the Caisse nationale d’assurance vieillesse des travailleurs salariés (National Old-Age Insurance Fund for Employees) verifies that the employee’s registration number in the national register for the identification of natural persons (NIR) or the pending identification number (NIA) shown on the said declaration corresponds to the civil status data shown on the same declaration.
If there is no registration number in the national register for the identification of natural persons and no pending identification number or if the registration number in the national register for the identification of natural persons or the pending identification number is incorrect in the pre-employment declaration, the Caisse nationale d’assurance vieillesse des travailleurs salariés will send the body mentioned in Article R. 1221-3 an identification report including, where it has been able to find it, the registration number for the national register of identification of natural persons or the standby identification number to be used. The body mentioned in the aforementioned article notifies the employer of the availability of this identification report so that, in particular, it can rectify or complete the data transmitted in the nominative social declaration.
