When an employer learns that an employee has more than one social security number, the employer should notify the :
Compensation and Employer Services
Railroad Retirement Board
844 North Rush Street
Chicago, Illinois 60611-1275
Items to Include
The correspondence should include:
- The employee's name;
- employee's address; and
- all social security numbers used or assigned to employee.
Upon advice from the Social Security Administration, the Railroad Retirement Board (RRB) will consolidate the employee's service and compensation under one number. If the discrepancy cannot be reconciled, the employer may be asked to file reports of employment. After the employee's account is reconciled, the employer will be notified of the social security number to be used to report the employee's future service and compensation.
