Ticket inspection

Buy your ticket before you board. You need network coverage at the moment of purchase, and the ticket is not valid until you have received it.

If you travel on city lines in the Trondheim area, you show the ticket during an inspection. On regional lines, night buses and night trams, you show it to the driver as you board.

Get a reminder before your ticket expires

If you use the AtB app, you can receive a push notification before your ticket expires. You turn this on under My profile → Settings → Notifications.

Buy a ticket for someone else

You can send tickets to others in the AtB app – single tickets, period tickets and multi-trip tickets. Both of you must be logged in and have the latest version of the app. The ticket appears in the recipient's app and is valid there.

Good to know

• A screenshot of a ticket is not valid. The ticket must be shown in the app.

• The ticket is valid in the app it is stored in. If you have sent a ticket to someone else, it is no longer yours.

• If you switch between t:kort and mobile, the switch must be completed before you board.

• You must be able to show your ticket – with a readable screen and enough battery for the whole journey. Many of our buses have USB sockets if you need to charge.

Send your order to 2027 before you board. You must have received the text message with the ticket before boarding – the time of purchase is stated in the message.

An SMS ticket cannot be forwarded. It is only valid on the phone it was bought with, and forwarding it is considered document forgery. If you want to arrange a ticket for someone else, use "buy for others" in the AtB app.

If you are having problems with the app, SMS is a good alternative.

Period ticket

The ticket is activated and valid from the date you selected when you bought it in the online store. On regional lines, you scan your t:kort at the driver on every journey. Remember to keep track of when the ticket expires, and that you have the right category.

Multi-trip ticket

Scan your t:kort on every journey – either on the card reader at the metro station or at the driver – so that one ticket is deducted or a valid transfer is shown.

Reminder before your ticket expires

You can receive an email 24 hours before your period ticket expires, and when you have two trips left. You turn these reminders on and off in the online store.

Remember to bring your t:kort. You cannot show your ticket afterwards.

Zone A tickets from a ticket machine or sales outlet

Tickets bought from AtB's own ticket machines, or at one of our sales outlets, are valid from the moment of purchase. On regional buses you must show the ticket to the driver. Keep the ticket until the end of your journey so that you can show it during an inspection.

Card or cash on board

A ticket bought from the driver is valid from the moment of purchase. Keep the ticket until the end of your journey so that you can show it during an inspection.

The penalty fare is formally called a tilleggsavgift (additional fare charge). The rates are:

If you received a penalty fare because you did not have proof of your discount entitlement, the amount may be reduced to NOK 150. To do this, you must show valid proof, ID and the penalty fare notice at the AtB customer centre within seven days.

If a child under the age of 15 travels alone without a valid ticket, no penalty fare is issued. Parents or guardians are contacted, and the incident may be registered as a penalty fare of NOK 0. In repeated cases, parents or guardians may be invited to a meeting.

If you forge a ticket, the matter will also be reported to the police.

Read more in our transport regulations.

You can pay in three ways:

• By online banking, using the payment details on the back of the penalty fare notice. Remember to state the penalty fare number in the message field – you will find it in the top right-hand corner of the front page.
• By card to the inspector.
• By card or cash at the AtB customer centre in Trondheim.

If you wish to appeal against the penalty fare, you must do so no later than 21 days after it was issued.

If you appeal on behalf of someone else, we need written authorisation from the person who received the penalty fare. This does not apply when guardians appeal on behalf of a minor.

You can send your appeal using our contact form or by post. Remember to include:

• Your name
• Your email address
• The reason for your appeal
• The penalty fare number (five digits)
• Your receipt (if you paid on the spot)

Appeals can be sent by post to:
