Définition
The Siren number is a nine-figure identifier attributed to each legal unit.
The first eight figures have no meaning. The ninth figure is a control figure to validate the number.
Remarque
This number is not significant; it bears no relation to the characteristics of the enterprise. It is allocated once and is not reused, even after the disappearance of the legal entity (death or terminating all activity in the case of an individual, winding up for a legal entity).
