The Joint Admission Matriculation Board (JAMB) has launched a portal where undergraduates of various institutions can check whether their admissions are recognised by JAMB or not.
It is important that you confirm your name from the matriculation list. Only candidates whose names are on this list are recognised as bonafide students from the various accredited institutions.

By implication, if your name is not on this list, your application to NYSC scheme for the one year National service shall be declined.
