On January 6, your bus lines change number in the Cœur d'Essonne region

A new numbering in the territory of Cœur d’Essonne

Why do the line numbers change?

The bus network in Île-de-France is made up of nearly 1900 lines, including 1500 in the greater suburbs, and the current numbering results in many lines having the same number.

The timetable and route search tools are regional, and it is therefore often complicated to find your line. For example, there are 13 bus lines bearing the number 10!

How to find your way in the new issues?

Île-de-France has been divided into departments and sectors, which each have a specific code. In the territory of Cœur d’Essonne all bus lines now start with 45.

Whenever possible, the old number was used to facilitate the change (examples: line 2 becomes 4512, line DM16 becomes 4542, etc.).

Express line numbers begin with the number of their department (examples: line M154 becomes 9114, line 108 becomes 9118, etc.)

What will this new number bring to users?

Users will be able to find their bus line more easily, because it will be the only one in Île-de-France to carry this number!

So, when we type their number into the search engines of the application or the iledefrance-mobilites.fr site, we will be able to directly access the information concerning them.
