1. If the group is an official group managed by a school or institution, and it is stipulated that student information can be shared within the group, then the student number can be shared within the group.
2. If the group is private or has no clear definition, it needs careful consideration. Because the student number belongs to public personal information, it may also contain some private information, such as birthday. In this case, sharing your student number in the group without your consent may infringe on your personal privacy.
3. In any case, we must abide by the relevant privacy protection laws and ethics.
Generally speaking, before sharing students' student numbers, it is recommended to know the relevant laws and policies. In case of doubt or uncertainty, please consult relevant managers or teachers.
