The fundamental difference between Interrail and Eurail is the residency of the traveler, as the two passes are otherwise identical in terms of the trains and countries they cover. An Interrail Pass is exclusively for citizens or legal residents of European countries (including the United Kingdom, Turkey, and the Russian Federation). If you live in Europe, you must buy an Interrail pass. Conversely, a Eurail Pass is for travelers who live outside of Europe, such as residents of the United States, Canada, Australia, or Asia. This distinction is strictly enforced; when you travel with the pass, you must carry a passport or residency document that matches the pass type you purchased. In 2026, the two brands have almost completely converged in terms of pricing and functionality. Both offer "Global" passes for travel across 33 countries and "One Country" passes for more focused trips. They both operate through the "Rail Planner" mobile app and require the same seat reservation fees for high-speed and overnight trains. Essentially, they are the same product marketed to different parts of the world based on where the traveler calls home, ensuring that both Europeans and overseas visitors can enjoy the same unlimited access to the continent's massive rail network.
