A system and method for ensuring safe delivery of items to an event, such as a conference or trade show. The system uses a controlled-access website or app and a program with a database operated by a security coordinator. All prospective attendees are vetted, and after being verified as bona fide attendees who qualify as a reliable exhibitor/shipper, are given access to the database for the purpose of obtaining (by download) a particularized set of coded labels to be applied to a particular item to be shipped. The coded labels are then printed, applied to the items to be shipped and sent to a staging location for screening. At the staging location, the security coordinator scans all coded labels of shipped items when they arrive, and the program compares the scanned data with the data in the database to see if the shipped items are associated with a reliable exhibitor/shipper. If there is a match, the shipped items can then be forwarded to the event, and if the shipped item does not bear a coded label that is associated with a reliable exhibitor/shipper, the item is moved to a remote location for further investigation.
