Lost & Found is always a valuable resource when you have lost something. I know how painful it is to be abroad, to loose something, and then having to search a lot, not for the things, but first for Lost & Found contacts, which often are outdated, unavailable, or not visible online.
Please find below the Lost & Found contact list updated in 2019. Print the contacts below or copy to your address book. They might be useful for your next trip to Lisbon / Portugal:
1) Lost & Found Official Government Website
They have a clean portal, where you can make searches by article stolen or lost, serial number, description, lost date, etc. The only downsize is that’s only available in Portuguese, so get help from a Portuguese friend and search for your lost item.
