University Identification Numbers (UINs)
University Identification Numbers (UINs) identify students, employees, and others in University of Illinois records. Each nine-digit UIN is unique and permanent across the entire System. UINs are never re-used.
Only units may request that a UIN be created; a person cannot request a UIN on his own behalf. See UIN Creation and Requests on the Treasury Operations' website for more information about the request process.
