Everyone loses something at some point!
Events may designate a lost and found area particular to their event. Typically this is an information desk in the lobby or the show office as that is where most attendees will check first. Items found by Moscone staff will be taken to that area as soon as possible during their shift.
At the close of the event those items may either be taken back to the offices of the event or left with Moscone Center Security Control
Lost items left at The Moscone Center are kept thirty (30) days from close of show (except for perishable items which are not kept). At that point anything that can be donated will, other items will be destroyed.
To check on the location of Lost and Found during a particular show please contact the Moscone Security Control room by dialing "4021" from any house phone or call the number listed on this page.
