Frequently Asked Questions
To travel by bus, you can use a wide range of transport tickets, including the Navigo pass. Individually, the Bus-Tram ticket, which allows you to make a bus journey, costs €2,05 (the t+ ticket has not been sold since 01/01/2025).
Don't have a ticket or change? You can take the bus! When you see your bus approaching, send Bus + your line number to the short number 93100. You will then receive an SMS that will serve as your ticket. For example, send Bus29 to 93100 if you take Bus 29. Then, show the SMS ticket to the driver on your phone screen when you board. The SMS ticket is only valid for an immediate trip on the bus without any transfers. The validity period is 1 hour from the time the SMS is sent (the duration is indicated in the SMS you will receive). Cost: 2.55 € excluding the cost of the SMS for phone subscriptions that do not include unlimited SMS.
You can travel on the Noctilien network with Navigo, imagine R, Mobilis, and Paris Visite passes. You can also take Noctiliens with Bus-Tram tickets or on-board access tickets. If you use Bus-Tram tickets, please note that you need to validate 1 Bus-Tram ticket for 2-digit lines and line N135, and validate 2 Bus-Tram tickets for all other lines.
