19 Per the Internal Revenue Service’s (IRS) W-2 instructions, **do not** accept Individual Taxpayer Identification Numbers (ITINs) in place of a Social Security Number. An ITIN is only available to resident and nonresident aliens who are **not** eligible for U.S. employment. ITINs are easily identified as they begin with the number 9.
