What is a USI?

The Unique Student Identifier (USI) is a government-issued reference code that identifies you as someone who has commenced or undertaken education or training within Australia. You keep the same USI for life as it’s your national education number.

All Curtin students* need a USI, including international students studying onshore in Australia, students undertaking a Curtin course through Open Universities Australia (OUA), Higher Degree by Research (HDR) students and domestic students who have previously applied for or been issued a Commonwealth Higher Education Student Support Number (CHESSN).
