Who can become member of ECSO?

All legal entity established in the EU and EEA/EFTA countries as well as the national, regional and/or local public administrations of these countries.

My company is member of a cluster/ Organisation / Association which is member of ECSO. Does this mean my company is also member of ECSO?

No. The membership of the Association you are member of does not provide you direct access to the work of ECSO. You can, however, benefit from the information distributed by your Association and voice your messages onto ECSO through your Association. To directly participate to the Working Groups and contribute to the work you should become member of ECSO.

Can a single person become member of ECSO (consultant, journalist, etc)?

No. Memberships are restricted to legal bodies.
