How do I activate the pass?
Your German Rail Pass must be activated before you start using it. This must be done within 11 months of the issuing date. German Rail Passes must be activated by a railway official, who will enter the first and last day of validity on the pass.
You can go to a DB ticket office to have your pass validated before you board your first train. If you arrive in Germany on a train from abroad, a ticket inspector on the train can also validate your pass.
You cannot enter the first and last day of validity on your pass yourself.
Please note that by months we are referring to calendar months. This means that if, for example, you purchase your pass on August 31, 2016, the latest day you can activate your pass is July 30, 2017.
