UIC shares U of I Box with UIUC and UIS, therefore, you may already have an existing U of I Box account from UIUC or UIS. Please create a ticket here so that your account can be converted for use at UIC.
If you have an External affiliation with UIC, please create a ticket with ithelp@uic.edu.
If your uic.edu email address is being used with a commercial Box account or a Box account with another organization, please create a ticket with ithelp@uic.edu.
Otherwise, to open a Box account visit the University of Illinois Box Signup, log in, and then toggle the U of I Box option to On (screenshots below). Or you can submit a ticket here and we will assist in the account creation.

Once you have done so, you can visit box.uic.edu to log into Box.
