Register anonymization is the removal of details that make a member identified or identifiable under GDPR Art. 4(1). Company law still requires the firm to keep the real register. What you clean is the copy that leaves the building. Keep no re-link key and Recital 26 takes that copy out of scope.
When this applies
A buyer asks for the members list during diligence. The statutory register stays exactly as it is. Anonymize the copy first, before it leaves the company.
How anonym.plus handles it
- Open the list in anonym.plus on a local device.
- It spots member names, addresses, and ID numbers.
- Swap each one for a non-reversible label for true anonymity.
- Keep no re-link key if you want it outside scope.
- Save the clean list on your device.
What you need to provide
- The list (XLSX, CSV, PDF, or export).
- Replace, with the reversible map turned off.
- Optional language setting for cross-border members.

Limitations & cautions
A holding size can act as a quasi-identifier. A lone 25% stake may point to one member after the name goes. If you keep a reversible map, the list is pseudonymous, not anonymous, and stays in scope.
Frequently asked questions
Does this change the official register?
No. Company law requires the firm to keep the real member list. anonym.plus cleans the copy you circulate, so the statutory record stays complete.
Anonymous or pseudonymous — what is the difference?
Pseudonymous output keeps a key that can re-link it, which Art. 4(5) still treats as personal data. Anonymous output drops that key for good. Only then does Recital 26 apply.
Does it handle cross-border members?
Yes. The tool reads 48 languages, so foreign names and ID formats are caught.
