- SIREN and SIRET numbers are unique identification numbers required by businesses operating in France.
- The SIREN number is a nine-digit business identification number that remains constant throughout the business’s existence, while the SIRET number is a unique 14-digit identification number assigned to each establishment or branch of a business in France.
- Both numbers are issued by the French National Institute of Statistics and Economic Studies (INSEE) and are used for various administrative and fiscal purposes, including TVA registration.
- Once registered, a business is issued a VAT number (TVA), which must be included on invoices and other relevant documents.
- Registration for SIREN/SIRET is done online or in person at the appropriate Centre des Formalités des Entreprises (CFE), based on your business activity.
