Travel documents (writ of passages, passports, travel papers) are official papers granting an individual the ability to travel across a border, enter a neutral zone, contested area, quarantine zone, or travel into another kind of restricted area. Travel documents may be required to be shown at a border crossing or gatehouse. They may be forged or stolen. Travel documents are used by spies, refugees, and tourists.
Obtaining travel documents and successfully navigating through an unfriendly checkpoint is a common motif in narratives.
