What is a “no match” letter?
In a “no match” letter, SSA informs you that the name and SSN you reported for an employee do not match SSA’s records. The letter explains the reasons for keeping accurate records and lists the SSNs that do not match SSA’s records. It also cautions you not to take any adverse employment action based on the letter against employees whose names and SSNs do not match with information in SSA’s records. A no match does not mean that an individual is undocumented.
