Siret number


Dernière mise à jour le :04/12/2019


The Siret number is an identifier of establishments.

This 14-figure numerical identifier is split into two parts : the first is the Siren number of the legal unit to which the Siret unit belongs; the second is usually called the NIC (internal classification number), and is made up of a four-figure number attributed to the establishment and a control figure used to validate the Siret number as a whole.
