Individual Taxpayer ID Number (ITIN)

The Individual Taxpayer Identification Number (ITIN) is a nine-digit number issued by the Internal Revenue Service (IRS) to individuals who are not eligible to obtain a Social Security Number (SSN). The ITIN is used primarily for tax filing purposes and is not a form of work authorization.

Non-resident aliens who receive payments from USC in the form of a check (fellowship, stipend, scholarship, honoraria, etc.) but who are not eligible for a Social Security Number are required to obtain an ITIN. If a scholarship or fellowship is applied directly against tuition, there is no need to apply for an ITIN.
