University Identification Numbers (UINs)

UINs are an electronic record numbers. Each UIN issued is unique and permanent across the entire U of I System—all its universities, locations, and programs.  A UIN is never re-assigned or deleted.

A UIN is required in order to request a NetID or a university ID card. However, UIN assignment does not authorize or entitle a person to receive any services. Each UIN is the property of the University of Illinois, and the use and governance of UINs are at its discretion, within the parameters of the law.   i-card Programs determines what data is needed to generate UINs, and we generate, assign, and maintain them.

UIN Lookups

If you need to know your own UIN, you may be able to retrieve it yourself.  Use the Find Your UIN lookup if you're certain the university has your Social Security number or Temporary Control Number on record.

How to Request a UIN

No one can request a UIN on his own behalf. We create UINs only at the request of current, non-student employees and authorized agents of affiliated organizations. UIN request conditions are as follows:

  • Are you hiring a new or former employee, student, or student applicant? 
    Don't request a UIN directly from us. The HR Front End ("HRFE") system for onboarding employees automatically triggers UIN generation or retrieval from our database.
  • Do you represent an Urbana, Springfield, or System unit?  And do you need a UIN (and/or NetID) for an external affiliate?
    You must use the AITS Affiliate NetID Manager service. This service interfaces with our UIN generation system.
  • Do you represent a UIC or UI Health unit? And do you need a UIN for an external affiliate?
    Log in at to submit a request to our Help Desk inbox. PDF forms are not accepted. Contact our Help Desk if you need UINs for 20 or more people.

All requests are processed on a first-in, first-out basis. Allow two business days for initial responses.  For the fastest response to your requests, follow the recommendations provided in  About University Identification Number Requests (PDF).
