This September marks a significant update: millions of business activity codes (SBI-codes) at the Dutch Chamber of Commerce (KVK) and Statistics Netherlands (CBS) will be revised. If entities such as banks, municipalities, notaries, or insurers fail to adapt to these changes, businesses might inadvertently lose access to loans, permits, or new contracts. The KVK urges business owners to verify their updated codes—but many remain unaware of the potential impact. (fd.nl)
The Impending Code Overhaul
Starting the first weekend of September 2025, the KVK and CBS will roll out an extensive adjustment to business codes across the country—affecting millions of registered companies. These codes serve as the formal classification of a company’s primary business activities and are essential in many administrative, legal, and financial contexts.
KVK’s Core Advice: Start with Your Activity Description
According to the KVK, every company or organisation has one or more SBI-codes listed in the Dutch Trade Register, linked to its official activity description.
“The codes show what your company or organisation does. In September 2025, many SBI-codes will change. Check now whether your activity description is still accurate. This ensures you will receive the correct SBI-code(s) after the update.”
By verifying the accuracy of your activity description today, you greatly reduce the risk of mismatches when the new codes take effect.
These seemingly small changes can have significant consequences:
- Subsidies and financing: Banks and funding bodies rely on SBI-codes when assessing eligibility.
- Permits and compliance: Municipalities use them to determine sector-specific requirements.
- Professional services: Notaries, insurers, and procurement systems may reject transactions if codes are incorrect or outdated.
Even if your day-to-day operations remain unchanged, an inaccurate code could cost you valuable opportunities.
What Business Owners Should Do Now
- Review your current SBI-code(s) in the KVK Trade Register.
- Check your official activity description for accuracy and relevance.
- Update the description if it no longer reflects your main business activities.
- After the September update, verify that your new SBI-code matches your business reality.
- Ensure all partners (banks, municipalities, insurers) have the correct information.
Act now to safeguard your business. Review your activity description in the Trade Register before September, because the right SBI-code tomorrow starts with the right description today.
Why This Matters
Without the right code:
- Loans or subsidies could be delayed or denied.
- Permits might be withheld.
- Contracts could be lost to administrative mismatches.
