First, check if there is a note in your mailbox. If this is the case, the package got delivered at your neighbour’s. If this is not the case, the package has been delivered to the nearest PostNL pick up point. Usually, you can pick up your package the next day. You have a week to pick up the package (pay attention to the opening hours of the pick-up point location). After a week, the package will be returned to us.
