Designation

Designations are unique membership numbers possessed by all members of the Justice League and the Team. They are read out by the Computer when a member enters any restricted areas of the Hall of Justice or Mount Justice. The Computer also reads out designations when someone is leaving Mount Justice or the Hall of Justice.

The system also allows authorized guests to use the tubes.
