A new phone number
In an effort to simplify the user journey, Île-de-France Mobilités is setting up a single telephone number project. This number is being rolled out gradually, by territory.
Eventually, passengers will be able to contact a single number throughout the Île-de-France region, to ask a question about public transport.
This service is already deployed in the Evry Centre Essonne living area. Do you have a question or information about your buses? You can contact us on 0 800 10 20 20.
