10. No-match letters are really the responsibility of the employee

when the employer submits the employee's record of earnings (and deducted taxes) to the Social Security Administration, they also submit name, date of birth and social security number.

if the employee is working under someone else's social security number, and using false name, the name and date of birth will be a non-match to the social security file.

the employer has to inform the employee of the non-match and confirm that he is spelling the employee's name correctly.

after that, it is the responsibility of the employee to get his social security record amended so it matches.

the employer can't take any adverse action against the employee, in fact it would be a serious breach of anti-discrimination laws if they did.
