Where? Activate your Rail Pass, for free, at a train station in a participating Eurail country.
When? Activation must be done within 11 months of the issuing date. Your Eurail Pass can only be used once it’s activated.
How? Go to a ticket counter of any major train station in one of the participating Eurail countries. An official will fill in the start and end dates of your travel and your passport number. Therefore, bring your passport. Finally, your rail pass will be officially stamped to validate it.
