The U.S. Citizenship and Immigration Services (USCIS) reported that there was a glitch when the revised Form I-9 was first published on November 14, 2016.  Numbers entered in the Social Security number field were transposed when employees completed and printed Section 1 using a computer. For example, the number 123-45-6789 entered in the Social Security number field would appear as 123-34-6789 once the form printed. The USCIS reports that it repaired and reposted the form on November 17, 2016.  The reposted form looks exactly the same as the one it replaced but the glitch is corrected.

Employers that downloaded the revised Form I-9 between November 14, 2016, and November 17, 2016, should check whether employee numbers on the Form I-9 are transposed.  Employers that downloaded the revised Form I-9 after November 17, 2016, should not be affected by the glitch. 

Employers who notice their employees' Social Security numbers are not written correctly should have their employees draw a line through the transposed Social Security number in Section 1, enter the correct Social Security number, and then initial and date the change. Employers should include a written explanation with Form I-9 about why the correction was made in the event of an audit.
