Hello Shazoivau44
Lost property objects are sent to the lost property central offices daily and are then registered. This registration enables a better classification of objects for the repatriation to their owners.
Therefore you have to file a lost property report. The easiest way to report a lost item is by filling out a lost property report online: www.sbb.ch/en/find
Please make an as detailed description as possible of your item and where/when you lost it.
On the basis of the incoming found property reports or found objects, you will be informed after 4 and 10 days on the status of your lost property report by e-mail.
You may find further information at sbb.ch/en/lostandfound.
I wish you good luck and a lovely day.
