Within the Schengen Area, which covers most of mainland Europe, there is typically no permanent passport control at internal land, sea, or air borders. However, it is a common misconception that you don't need a passport at all; you are still required to carry a valid ID (and a passport for non-EU citizens) as "spot checks" can be performed by local police or during temporary border reinstatements for national security. As of 2026, several countries like Germany, France, and Italy have periodically extended temporary internal border checks due to migration and security concerns. Furthermore, if you are traveling between a Schengen country and a non-Schengen country (like the UK or Ireland), you will still have to pass through full passport control and the new EU Entry/Exit System (EES) biometric checks.
