As of January 2026, the "49-euro ticket" (now officially called the Deutschlandticket and priced at €63 per month due to a price increase) is a digital-first subscription. To check its validity, you should look for the active QR code in your provider's app, such as the DB Navigator or a local transit app like BVG FahrInfo. The ticket is only valid for the current calendar month; if you can see a "current" QR code with the current month's date, it is active. If you use a physical smart card (Chipkarte), you can often check its status at a ticket vending machine or by having a conductor scan it. Remember that the ticket is a subscription that automatically renews on the 1st of every month. If you haven't cancelled it by the 10th of the previous month, your bank account will be debited, and your ticket will remain valid for the upcoming month. Always carry a valid ID, as the ticket is personalized and non-transferable; an inspector will verify that the name on the digital ticket matches your photo identification.
