To sustain accurate and expeditious mail delivery services, NIH activities should notify the Mail Customer Service Branch in writing as soon as possible of a pending move. Include in this notification when mail delivery should be stopped at the old location and started at the new location. Also include a list of the employees who should receive mail at the new location.
