If you have lost your ID on the campus, please contact the Registrar's Office, because this is where all found student IDs are handed in. If it isn't there, you will have to transfer 15.00 € for a replacement ID to the following account:
Ruhr-Universität Bochum
IBAN: DE47430500010001495860
BIC: WELADED 1BOC
Reference: your name and your student number (Matrikelnummer)
By presenting an account statement or a screenshot showing that the money has been debited, you can pick up your new student ID at the Registrar's Office. Please bring a passport photo and your ID card or passport.
