The NACE code (Nomenclature statistique des Activités économiques dans la Communauté Européenne) is a European system used to classify companies by their main economic activity. Every company in Luxembourg receives a NACE code when it registers.
This code isn’t just for statistics. It can influence your Chamber of Commerce contributions, determine how regulators view your activity, and even affect access to grants, public tenders, or sector-specific support.
Luxembourg follows its national version called NACELUX, which reflects the structure of NACE Rev. 2.1, the latest update introduced in 2023.
Who assigns the NACE Code in Luxembourg?
The National Institute of Statistics and Economic Studies (STATEC) is the authority responsible for assigning NACE codes. When a company registers with the Trade and Companies Register (RCS), the information submitted is reviewed by STATEC, which independently determines the appropriate code.
Assignment is based on the activity that generates the greatest share of added value, not necessarily the one listed first on the registration form. STATEC may also list secondary activities if they are significant, but only one principal activity is registered as the reference.
Where can a company view its registered NACE Code?
Companies can verify their registered NACE code using the official tool on MyGuichet.lu. The tool allows you to search by company name, NACE code, or registration number.
This classification is also visible on the company’s profile in the Luxembourg Business Register (LBR) and is integrated into official datasets maintained by STATEC and Eurostat.
What if the assigned Code is no longer accurate?
If your company’s main activity has changed, or if the current code is no longer appropriate, you can request a modification by contacting STATEC. However, changes are made only for statistical purposes, and STATEC will only process requests that are duly justified.
To initiate the request, companies should provide the following details through the official contact channel designated by STATEC:
- National identification number (and RCS number, if available)
- Legal name of the company
- Description of the current principal activity (the one generating the most value)
- The date this activity began
Modifications are only processed where the company’s main activity has materially changed. If the principal activity remains the same, no update is required.
What is the impact of the NACE Code on companies?
Even though NACE codes are statistical by nature, they can have practical implications in Luxembourg:
- Annual contributions to the Chamber of Commerce may depend on the assigned activity type.
- Surveys and reporting obligations may be based on sector classification.
- Licensing or supervision in regulated sectors may reference the registered NACE.
- Investor disclosures, grant eligibility, or classification in public databases may rely on NACE codes.
- Misclassification can affect your visibility in sectoral statistics, competitive benchmarks, or access to policy support.
What should companies do now?
Companies should consider the following steps:
- Check the current NACE code on MyGuichet or the LBR.
- Review whether it accurately reflects the principal activity generating the most value.
- Request an update from STATEC only if there has been a material change.
- Document the business model clearly if challenging the classification, especially for financial entities.
- Be aware of how NACE codes affect dues, data, and reputational standing.
