The original "9-euro ticket" was a limited-time promotion in Germany during the summer of 2022, but the question of personalizing German transit tickets remains highly relevant in 2026 for its successor, the Deutschlandticket (49-euro ticket). For both the historical 9-euro ticket and the current Deutschlandticket, you must write your name on the physical ticket or have it digitally linked to your verified account. These tickets are strictly non-transferable. If you are using a paper version or a printed QR code, there is a designated line for your first and last name; failure to fill this out can result in the ticket being declared invalid during a spot check, leading to a "heavy user fee" (fine) of at least €60. Because these tickets are heavily subsidized by the German government to encourage public transport use, ticket inspectors are very strict about checking ID. You should always carry a valid photo ID (like a passport or national ID card) alongside your ticket to prove that you are the person named on the pass.
