Taxpayer Identification Number

It is issued either by the Social Security Administration (SSA) or by the IRS.

If you do not have a Social Security Number (SSN), you must obtain an Individual Taxpayer Identification Number (ITIN) for tax-related documents. An ITIN is a tax processing number available for international students and scholars who cannot get a Social Security Number (SSN).
