IF there is an issue with the SS number when the employer is verifying they will/can ask to see the card to clear up the problem.
http://www.ssa.gov/employer/SSNcard.htmOften employers ask to see an employee’s Social Security card. But, do you really need to see the card? Since 1936, Social Security has issued over 30 different versions of the Social Security number (SSN) card which makes it difficult to recognize a valid card. Sometimes when you ask an employee to show you their card they can’t find it. In either case, you don’t have to send them to a local Social Security office.
Consider using the free Social Security Number Verification Service (SSNVS) which allows registered employers to quickly verify whether a person’s name and SSN match Social Security’s records. It saves you and the employee time.
For more information about SSNVS visit Employer W-2 Filing Instructions & Information. Learn more about the New Security Features of the Social Security Card.
http://www.ssa.gov/employer/critical.htmIf you discover an employee's SSN is incorrect, you should ask to see the employee's Social Security card to ensure the name and SSN are shown correctly in your payroll records. If the information matches, ask the employee to check with any Social Security Office to determine and correct the problem. Document any action you take to obtain the correct name or SSN and continue to report the employee's earnings using the SSN given to you. If you receive a corrected name or SSN from the employee after you filed the Form W-2, submit a Form W-2C to make the correction.
It's late and I'm tired, I hope this makes sense.
