Do not email documentation containing your SSN or TIN; email is not secure.

International Students

This requirement does not apply to international students who are not eligible for a United States SSN or TIN.

CU Boulder Employees

You may have reported your SSN to HR, however, our systems do not currently communicate and you will need to report it to the Office of the Registrar as well to fulfill this requirement.


CU Boulder protects the confidentiality of personally identifiable information and will not disclose an SSN or TIN for any purpose not permitted by law or policy (including FERPA) without your consent.

*Federal Requirement

Section 6109 of the Internal Revenue Code requires you to provide your correct SSN or TIN so CU Boulder can file Form 1098-T (Tuition Statement) with the IRS and provide a statement to you.

For information about tax benefits for higher education, see IRS Pub. 970 or the CU Boulder Bursar's Office tax information page.
