What is a SIREN number?

The SIREN ('business directory identification system') number is a unique code used to identify a company.

The SIREN number is assigned by INSEE and does not change. It is issued for the entire life of the company.

The SIREN number is composed of 8 digits and a control key, or a total of 9 digits, presented in 3 groups of 3 numbers.

The SIREN number is the same for all the establishments of a given company, unlike the SIRET number.
