1Why CAEN codes matter

Every company activity has a CAEN code. A company may legally carry out only the activities registered with the Trade Register. If you start something new, for example selling online alongside repairs, you add the right code first.

Companies set up before 2025 must move their activities to CAEN Rev. 3 codes by 25 March 2027. See how the update works.

2What you can change

  • Add secondary activities, as many as you need.
  • Drop activities you no longer carry out.
  • Change the main activity, the one that brings most of the income.
  • Set where each activity happens: at the registered office, a place of business, at clients' premises or online.

A PFA can have at most 5 activities; a sole proprietorship or family business at most 10. An SRL has no limit.

How many CAEN codes can an SRL have?

As many as it needs: one main activity and any number of secondary ones.

Can I change the main activity?
