What Is a Company Number Register?

A company number register is an official system that assigns unique identifiers to businesses. In France, this system is managed by INSEE (the National Institute of Statistics and Economic Studies), which issues two main identification numbers:

  1. SIREN Number: This is a nine-digit code that identifies your company as a legal entity in the French registry.
  2. SIRET Number: This 14-digit code is specific to each branch or establishment of a company. It combines the SIREN number with a five-digit location code called the NIC (Numéro Interne de Classement).

Both numbers are critical for verifying the legal existence of your business and for fulfilling administrative requirements, such as filing taxes, creating invoices, and opening corporate bank accounts.

When and Why Do You Need a SIRET Number?

The SIRET number is required in several key scenarios:

  1. Furnished Rental Activities:
    Renting out furnished properties in France is considered a commercial activity by the French tax office. This means you must register your rental operations and obtain a SIRET number, even if you already own a business abroad.
  2. Unfurnished Rentals:
    Renting unfurnished properties, however, is not classified as a commercial activity and does not require a SIRET number. While you’ll still need to declare your income on your tax return, you’ll use different forms for this purpose.
  3. General Business Operations:
    Any business conducting commercial, professional, or industrial activities in France must register and obtain a SIRET number to comply with French regulations. This applies to entrepreneurs, freelancers, and multinational corporations alike.

How to Register Your Company in the French Company Number Register

Obtaining your SIRET and SIREN numbers involves incorporating your business into the French company number register. Here’s a step-by-step guide:

  1. Select the Appropriate Business Structure:
    Depending on the size and scope of your operations, you can choose from various business structures, including:
    • Entreprise Individuelle: Ideal for sole proprietors.
    • SARL: A limited liability company suitable for small to medium-sized businesses.
    • SAS: A flexible corporate structure for larger businesses or startups.
  2. Prepare Your Documentation:
    You’ll need:
    • Proof of identity.
    • Proof of address for both personal and business premises.
    • A detailed description of your business activity.
  3. Submit Your Application to the Business Registration Center (CFE):
    Your application will be processed by the Centre de Formalités des Entreprises (CFE). Once approved, your business will be added to the French company number register, and you’ll receive your SIREN and SIRET numbers.
  4. Activate a Corporate Bank Account:
    A corporate bank account is mandatory for financial transactions in France. You’ll need your SIRET number to open this account.

SIRET vs. SIREN Numbers: Key Differences

Many people confuse the terms SIRET and SIREN numbers, but they serve different purposes:

  • SIREN Number:
    • Identifies the company as a whole.
    • Remains constant throughout the life of the business.
  • SIRET Number:
    • Identifies individual branches or establishments of the company.
    • Can change if a business moves or opens additional locations.

Think of the SIREN as the “parent” identifier, while the SIRET provides more specific details about where business operations are conducted.

Managing Multiple Properties Under One SIRET Number

If you own multiple rental properties in France, managing them under a single SIRET number can simplify your administrative responsibilities. Here’s how it works:

  • Rental income from all properties is consolidated into a single tax return.
  • You’ll only need to maintain one company registration within the company number register.
  • Any changes, such as acquiring new properties, must be updated in the register to reflect accurate information.

Why and When Should You Deactivate a SIRET Number?

Once your business is registered and your SIRET number is active, the French tax office will expect annual tax returns, even if the business generates no income. Failure to file these returns can result in penalties of up to €1,500 (€150 per missing document).

To avoid unnecessary obligations, you should deactivate your SIRET number if:

  • You’re no longer conducting business activities.
  • You’ve sold your properties or closed your operations in France.

Deactivating your SIRET number exempts you from filing tax returns and prevents future complications with the authorities.

Why Registering in the Company Number Register Can Be Complex

The process of registering in the French company number register can be daunting for foreign entrepreneurs and first-time business owners. Common challenges include:

  • Navigating French bureaucracy and legal jargon.
  • Ensuring accurate documentation to avoid delays.
  • Understanding complex tax regulations.

Mistakes during registration can result in costly penalties or administrative setbacks. This is why many businesses turn to professional services for assistance.
