Can you buy a ticket in the app after boarding in Denmark?
Buy first, then board
Short answer
No. Under the common nationwide travel rules valid from 30 June 2026, a ticket for DSB trains, the metro, Lokaltog and light rail must be bought before you board. With a mobile ticket it is your own responsibility that the ticket has been fully received on the phone before you get on. It is not enough that you have started the order. If an inspector checks you before the ticket has arrived, you can get a kontrolafgift.
Why
- The ticket must be on the phone before boarding.
- A started order does not count.
- The rule covers trains, metro, Lokaltog and light rail.
Details
On buses a single ticket can usually be bought in cash when you board, but some routes are exceptions.
Tip
Buy the ticket while you are still in the station hall, where the signal is often better than on the platform.
What may differ
Rules for buying on board can differ between operators and routes, so check with the operator.
Common misconception
Many think you can buy the ticket once you have found a seat.
What actually happens
On trains and the metro the ticket must already be on your phone when you board.
