Sorry to hear about this.... losing your wallet is a major complication.

Mine was stollen one year ago, and was struggling with it for a few months....
You will have to go to the police to report your missing permits and licences. Otherwise, you won't be able to get copies. Would recommend to call the lost and founds at the SBB and post office (sometimes people just drop stuff in the mail boxes). At least this was what i was told....
Best of luck,
Lucy.
