Each centre that intends to participate in the PO-ERN needs a national designation; if such a designation is not given, a centre is not eligible to become a full ERN-member.
Therefore we urgently recommend our envisaged ERN partner centres to contact your national ERN contact points and inform them about your interest in a national designation for the ERN application. The national designation process is not an EU-wide process, but differs between the individual member states.
More information: please find here a list of national contact points provided by the EU.
