All participants are potential group leaders. As an applicant, during the application period, you can add up to 4 friends who match the eligibility criteria of DiscoverEU even if you have indicated in the application form that you want to travel alone. To enable your friends to join your application, you will have to provide them with your application code that you will receive via email. This will become the group code. They will have to apply during the application period, enter the group code, and be eligible to participate (see Rules section 2. 'Eligible applicants').
