University Identification Numbers

University Identification Numbers (UINs) are the primary elements used to identify persons associated with the University of Illinois. A UIN is a nine-digit record number used across the entire U of I System—at all universities, programs, and locations. Once a UIN is assigned to you, it is permanently yours; no additional or different UIN is ever assigned for your records. UINs are not related to Social Security numbers in any way.

i-card Programs is the data owner of UINs, and it generates, assigns, and maintains them. We determine what data is needed to generate a UIN. Currently, we require at least a last name and birth date to generate a UIN.

Assignment of a UIN 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 permanently maintains assigned UINs.
