As soon as possible you need to either return on the site of probable loss or contact and/or go to the service or the person responsible for collecting items found i.e. police station or lost and found office nearest to the likely place of loss. However a simple and smart way is to use the LOFOX platform to report and inform the largest possible number of people of the loss of your items. Then the latter are subject to a continual and regular research in the database of items declared found in the LOFOX platform.
