DB Komfort Check-in is the self-service check-in feature built into DB Navigator for ICE and IC trains. Instead of waiting for a ticket inspector to walk through the carriage, you check yourself in from your phone, choose a free seat, and ride in peace. Before using it for the first time, brush up on how German train tickets work so you know which ticket type you have bought.
Quick Answer: What Komfort Check-in Does
- Self check-in via the app — no physical ticket control on board for ICE/IC routes
- Any free seat, no extra cost — sit down, then enter the coach and seat number in DB Navigator (or scan the seat’s QR code)
- Works with Sparpreis and Flexpreis — same long-distance tickets you already buy
- No printed ticket needed — the green-checked-in screen on your phone is the ticket
- English-friendly — the entire flow is available in English in DB Navigator
When to Use It (and When Not To)
Komfort Check-in covers most ICE and IC long-distance journeys. If your ticket is for an ICE or IC train and was bought in DB Navigator or bahn.de, you can use Komfort Check-in. It is not available for regional trains (S-Bahn, RB, RE, IRE) or for tickets sold by third-party resellers that do not sync with DB Navigator.
Step-by-Step: How to Use DB Komfort Check-in
Step 1: Buy Your Ticket in DB Navigator
Search your journey, choose an ICE or IC train, and pick a Sparpreis or Flexpreis fare. The ticket lands in the “My Trips” / “Meine Reisen” section immediately after payment — no printer needed. If you have not used DB Navigator before, the DB Navigator app guide walks you through account setup, language switching, and buying tickets.
Step 2: Open the Ticket Shortly Before Departure
Tap the trip in “My Trips”. The “Komfort-Check-in” button activates shortly before the train departs — DB publishes no fixed 15- or 30-minute threshold. If the button is grey, the ticket is either too early or for a train where Komfort Check-in is not enabled.
Step 3: Sit Down and Enter Your Coach and Seat Number
There is no graphical seat map in Komfort Check-in. Take any free seat, then in DB Navigator enter the coach number (Wagen — shown on the overhead displays and on the outside of the carriage) and the seat number (Platz — printed on or above the seat). You can also scan the seat’s QR code to fill both in automatically.
Step 4: Confirm the Check-in
Tap “Activate check-in” / “Check-in aktivieren”. The ticket changes to a green-checked-in state. Your coach (Wagen), seat number (Platz), and check-in timestamp are now visible on the screen. Board the train and sit in your chosen seat — the conductor will scan the green ticket when they pass through.
Step 5: Board and Ride
Show the checked-in ticket screen if a conductor asks. Unlike a typical ticket inspection, you do not need to fish out a paper printout, validate anything, or stamp a regional Entwerter — the green check-in is the proof of purchase and check-in combined.
Common Tourist Questions
📱 Do I Need Internet to Activate Komfort Check-in?
You need a working data connection when you tap the check-in button. After that, the app caches the green status. If your phone drops signal on the train, the checked-in ticket is still valid — DB Navigator stored the confirmation locally.
🎫 What If I Forget to Check in Before Boarding?
You can still activate Komfort Check-in while on the train. Open the ticket, tap the check-in button, pick a seat, and confirm. The conductor may ask you to step into the aisle to complete the flow if you have not done it when they arrive — doing it before they come saves everyone time.
🚆 Does It Work on Regional Trains?
No. Komfort Check-in is only available on ICE (Intercity-Express) and IC (Intercity) trains. Regional trains (RB, RE, S-Bahn) still operate classic ticket checks. The delays, cancellations and refunds guide explains how passenger rights differ between long-distance and regional trains.
🪑 Is It the Same as a Paid Seat Reservation?
No — Komfort Check-in does not reserve a seat, it just lets you check in on the seat you have taken. Anyone boarding after you can sit in the same seat if you do not board quickly. If you want a guaranteed seat (especially in the quiet zone or family area), buy a paid seat reservation through DB Navigator.
When Komfort Check-in Saves the Most Time
- Off-peak ICE trains where most seats are free anyway
- Quiet early-morning or late-evening departures when conductors walk through less often
- Connections with tight transfers where standing in line for a reservation would mean missing the train
- Tourists who do not speak German — the entire flow is in English and removes the only German-language moment on board

Step-by-Step Instructions
Buy or load your digital ICE/IC ticket in DB Navigator
Buy a Sparpreis, Flexpreis, or Super Sparpreis ICE or IC ticket through the DB Navigator app or bahn.de — the ticket lands in My Trips. Paper tickets from a DB Automat or counter do NOT qualify; Komfort Check-in only works with digital tickets bought through DB Navigator or bahn.de.
Board and take your seat
Board your ICE train (or selected IC) within Germany. Find your reserved seat or any free seat. Have your phone with DB Navigator open and connected to the internet. The Komfort Check-in button appears shortly before departure — not 15 or 30 minutes before.
Tap the Komfort Check-in button in your ticket
Open DB Navigator, tap My Trips, then your ticket. The Komfort Check-in button activates shortly before departure. Tap it as soon as you are seated — if you wait too long, a conductor may inspect your ticket first and Komfort Check-in locks out for the rest of the journey.
Confirm your coach and seat number
With a reservation: confirm the coach and seat number match your reserved seat. Without a reservation: enter the coach number (visible on overhead displays in the carriage) and seat number (printed on the back of the seat in front, or use the QR-code scanner in the app). BahnCard number is optional and auto-fills if stored on your account.
Tap Check in now and ride ticket-inspection-free
Confirm with Check in now. The ticket turns green, the train crew sees your check-in status on their device, and in most cases you will not be inspected. Your seat reservation display may also show your name, so other passengers know the seat is taken. You can change seat once via the Change seat (Umsetzen) function if needed.
