How do I activate my Eurail pass?
You need to activate your Eurail pass in a European train station before you can start using it. It must be activated within 11 months of the issuing date.
Once in Europe, simply go to the ticket office of any large train station and have a railway official activate your pass. It's not possible to activate the pass yourself.
The railway official will fill in the start and end date of your pass, as well as your passport number. They will also stamp the pass in order to validate it.
Activation is only possible at train stations in participating Eurail countries.
Please note that by months we are referring to calendar months. This means that if, for example, you purchase your pass on September 30, 2016, the latest day you can activate your pass is August 29, 2017.
