You should use your UID # as your User ID for the CSU Express Web access. To assist
current students and staff during the initial phase, CSU Express will accept your
new UID as well as your social security number. However, only your UID will be visible
Chicago State University follows all legal requirements for use of SSNs. The UID system
will help to ensure that your SSN is handled in a confidential manner. It will be
used for mandated business functions such as tax reporting to federal and state government
agencies. It will also be used in conjunction with insurance and retirement programs,
student financial aid programs, and other official university business activities
In response to the growing concern by all campus constituents regarding identify theft
and the confidentiality of individual Social Security numbers (SSNs) Chicago State
University launched a process to assign a unique, non-SSN campus identifier for students,
faculty and staff. The University is committed to protecting the privacy of its students,
staff and faculty.
Yes. In accordance with the Privacy Act of 1974, the disclosure of your Social Security
number to the University is generally voluntary. However, federal and state laws require
the University to collect your SSN in order to provide employment and student financial
Students who provide the University with their SSN help to ensure: timely processing
of admission applications; the integrity of their student records; timely responses
to requests for information after graduation; receipt of all appropriate tax credit
for tuition under the Taxpayers Relief Act.
If a student chooses to withhold their SSN at enrollment, but at some later time provides
it, for example, to obtain a loan or employment, they increase the risk that a clerical
error could ‘disconnect’ their earlier records with their newer records. The student,
more than the University, benefits from the submission of his or her Social Security
number at the earliest possible time.
Newly hired employees must supply their SSN for state and federal tax and reporting
requirements, employee benefit processing (medical insurance, life insurance, retirement),
background investigations and payroll processing.
Your UID number can be used to access CSU Xpress as well as other university systems
that previously required use of your Social Security Number. The unique UID may be
used across systems, application and business processes throughout the lifetime of
an individual relationship with Chicago State University. The sticker/label that is
sent to you with your UID number should be affixed to your current cougar One ID card.
In this way, your ID card can still be used as before.
Students, faculty and staff with access to CSU Xpress can still enter their SSN to
link to their UID number. When the SSN is entered only the UID number will be visible.
Staff without access to CSU Xpress can call Human Resources to obtain their UID number.
The UID number should be treated the same as your SSN. Do not share it with others
or leave your ID card where others will have access to your UID number.
No. Your payroll check will continue to show the last four digits of your social security
No. The UID will not be used as an identifying number for reporting to retirement
systems or insurance companies. It is still necessary to use SSN for these purposes.
