Why change line numbers?
The Ile-de-France bus network is made up of about 1,900 lines. Lines whose numbering systems coexist, but do not resemble each other with very different names and duplicates in line numbers (there were up to 19 lines 2 on the entire network) which complicate the understanding of the network.
In order to make it easier for passengers to understand, the operation of route planners and consolidate the project to build a single public transport network on a regional scale, Île-de-France Mobilités is continuing to renumber all the lines in the outer suburbs.
How do I find my way around the new issues?
Île-de-France has been divided into departments and sectors, each of which has a specific code. In our territory, all bus lines will have 4 digits and will now start with the prefix 65 (65XX).
As much as possible and in order to simplify this evolution, the current number will be kept with the addition of the 65 area code (e.g. the 2 becomes the 6502, the 56 becomes the 6556...).
There are two exceptions to this change:
- The express lines will also be composed of 4 digits with the prefix 78 (corresponding to the number of the department). Ex: X409 becomes line 7809
- The special school routes (CSS) remain unchanged.
