The Social Security Administration has mailed more than 570,000 “No Match” letters to employers since March 2019, which indicates the resumption of a practice that has been suspended since 2012. A “No Match” letter would be sent to an employer indicating that the names of some of their employees do not match the supposedly corresponding social security numbers.
While the notices do not necessarily require an employer to take any action other than to reconcile mismatches, any notification of mis-matches to workers is likely to result in any undocumented workers resigning for fear of impending immigration enforcement actions by the Federal government. Obviously, this could create some labor shortages in certain industries, at least in the short-term.
