Interrail Passes can only be used by European citizens and permanent residents of Europe. You'll find the full list of participating countries below, plus loads of other useful information. If you're a UK resident, Brexit doesn't affect the Interrail Pass. You can still purchase and use one as normal.

Yes, residents of the United Kingdom are fully eligible to use an Interrail Pass for travel across 33 European countries. There is a common misconception that "Brexit" ended the UK's participation, but Interrail is managed by Eurail B.V., which is an association of European railway companies, not an EU government body. UK citizens use the Interrail Pass, while non-European residents (such as Americans or Canadians) use the Eurail Pass. The most important rule for UK residents is the "Inbound/Outbound" rule: your pass generally only allows for two journeys in your home country—one to leave the UK (e.g., taking the Eurostar from London St Pancras) and one to return. Once you cross the English Channel, the pass provides unlimited travel on participating national networks. In 2026, the "Mobile Pass" has become the standard, allowing UK travelers to manage their entire itinerary and seat reservations through the "Rail Planner" app.
