Below is a list of the members of the Institute for Language and Communication Institute:

- some 150 people are assigned to it by right (academic, scientific and administrative staff)
- some 40 people have chosen to join the Institute (e.g., scientific collaborators, visiting researchers, members assigned to another institute who request affiliation to the ILC, etc.), not to mention emeritus members.

The ILC identity card establishes the number of each of them by status.
