The young citizen - or his legal representative - must do so at the town hall from the day he turns 16 with his parents' family record book and his identity card.

JDC is Defence and Security Awareness Day, where young people will meet men and women in the defence community. A test to detect reading difficulties is also scheduled. At the end of the JDC, an individual certificate of participation is issued to contributors. This document is requested when registering for examinations or competitions subject to the control of the public authority.
