Whether you should carry your physical passport while walking around Europe in 2026 depends on the local laws of the specific country, but carrying it is generally recommended for non-EU citizens. In many European countries, such as Spain, Italy, and Germany, the law requires everyone to carry a valid form of government-issued photo identification at all times. For Americans, Brits, and other non-EU travelers, a passport is the only universally accepted ID for this purpose; a driver's license often does not legally suffice for immigration checks. Furthermore, as the Entry/Exit System (EES) and ETIAS are fully implemented in 2026, police may occasionally perform spot checks to verify your legal stay duration (90/180 day rule). However, because of the risk of theft in tourist hotspots, many travelers carry a high-quality color photocopy or a digital scan on their phone while keeping the original in a hotel safe. If you choose this "safe" route, be aware that a strict officer may still insist on seeing the original document, which could result in a trip back to your hotel or a fine.
