Employers are responsible to annually report addresses for new hires in the previous year.  Address changes are reported by the employee, not the employer. 

Click BA-6a under the Forms menu.  This brings up a blank BA-6a screen.  Enter the employee identifying data as usual.  Only the first five letters of the surname are required but a complete last name may be helpful.  Keep in mind that these are new hires and, as such, may be new records at the RRB.  Entry of a middle initial is optional.  Type the address information and click the approve button.
