Legal entities in Member States can participate and receive funding in all parts of Horizon Europe. However in some call topics, limitations or conditions may also be attached to those entities which are controlled directly or indirectly by entities from ineligible countries (Third Country) [Article 22.5 of the Horizon Europe Regulation].

In general legal entities in Member States can coordinate projects in all calls with the exception of calls under the widening and spreading excellence part of Horizon Europe. In these calls only the so called widening countries and outermost regions of Member States can coordinate projects.
