Are you a student of the University of Antwerp in academic year 2024-2025?
Then you use the request "Re-enrolment" in your SisA self service to re-enrol after 16 July 2025 to re-enrol in the academic year 2025-2026. The instructions can be found in the helpdesk.
Please note that re-enrolments should take place before 04 October 2025. In some cases, enrolment after 03 October is possible but you will always need the permission of the faculty concerned.
Only re-enrol if you actually want to continu with your studies. A re-enrolment is always binding and could mean paying a tuition fee.
