The Lock Box is available in five sizes. However, sizes are different at every postal facility. The Postmaster will assign a Lock Box of a certain size in accordance with offices' needs and availability of boxes within the facility. This is a premium service offered for a fee to customers who require more than the general or carrier delivery available to all Postal customers, and who are required to use caller service. Caller Service entails the use of sacks, pouches, trays, bundles and other containers.
Mail is handed to the customers at a call window or from a loading dock.
Utilization of Post Office Boxes should be reviewed periodically. If possible, all Service Center post office boxes will be located at the same Post Office and will bear the zip code of that post office. The use of improper or inadequate addresses is one of the major problems in our mail management program. All mailing lists, address files, etc., should be reviewed twice yearly for accuracy. This address is used to receive general inquiries sent First Class Mail and most freight and bulk mail.
