Company SIRET number

What is a SIRET number?

The SIRET ('business establishment directory identification system') number is a unique identifier assigned to each business establishment. The SIRET system was created in 1973 and registration is compulsory.

It makes it simple for the government to deal with businesses. The SIRET is a 14-digit number assigned by INSEE (the national institute for economic research and statistics) as soon as a business establishment is created.

The first 9 digits are the company's SIREN ('business directory identification system') number. The last 5 comprise the NIC ('internal classification number').

The NIC is composed of 4 digits that distinguish the sites of a given company in sequential order and a final check digit to confirm the validity of the SIRET code.
