An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service. The IRS issues ITINs to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain, a Social Security number (SSN) from the Social Security Administration (SSA).

The Internal Revenue Service (IRS) is implementing significant changes to the Individual Taxpayer Identification Number (ITIN) program. For additional information, please visit the ITIN page at IRS.gov.
