Unique Student Identifier

Unique Student Identifier (USI) is a unique educational reference number issued by the Australian Government to all higher education students (including universities, TAFEs and independent tertiary colleges) for the purpose of collecting information about a student's training and study activity, and their movements within the VET and higher education systems in Australia.

The Unique Student Identifier is for life and is a requirement for all higher education students in studying Australia to obtain one. Both domestic and international students are included in the scheme, and the USI is independent of a University ID number as it is managed on a nationwide scale.
