A new numbering system in the Centre and South Yvelines area
Why is the number of your bus line changing?
The bus network in Île-de-France is made up of nearly 1,900 lines, and the current numbering system means that there are many lines with the same number.
The timetable and route search tools are regional, so it is often difficult to find the line you are interested in. For example, there are 13 bus lines that have the number 10!
How do you find your way around the new issues?
Île-de-France has been divided into departments and sectors, each of which has a specific code.
In the Centre and South Yvelines area, all your lines are now renamed from the area code "53" and all our school bus lines by "52", for greater consistency and legibility (e.g. Line 2 becomes line 5202 and line 31 becomes line 5231). Throughout the Île-de-France, Express lines will be assigned a code for their department followed by their own number. (Ex: Express line 11 becomes line 7811). Only the night buses and Transport à la Demande (TàD) remain unchanged.
What will this new issue bring you?
You will be able to find your bus line more easily, because it will be the only one in Île-de-France to have this number!
Thus, when you type his number in the search engines of the application or the iledefrance-mobilites.fr site, you will be able to directly access the information that concerns you.
