You must immediately cancel it in the "Lost or Stolen Badge" section in your subscriber area or by calling + (33)9 708 08 765. This operation is final and will block the use of the Bip&Go badge at tolls. There will be a fee for your lost/stolen badge.
If you request a new badge, issuing and activation fees will apply at the current rate.

If you find your Bip&Go electronic toll payment badge, return it to a Bip&Go agency in France or send it by post to the following address:
Bip&Go
Echangeur des Essarts
Route de Oissel, CS 80077

Here is a quick and easy tutorial to enable you to stop your badge from your subscriber area:

See question: How do I use my badge in a car park with electronic payment?

If you insert your badge into the heat-resistant sleeve included when you subscribed, it will not be detected when you go through the tolls.
When you want to use the badge again for your journeys, take it out of the protective sleeve and reposition it in its holder on the windscreen.

Yes – the Bip&Go electronic toll payment badge is not connected to one particular vehicle. It can therefore be used for the light vehicle (class 1, 2 and 5) of your choice. Trips are billed to the contract holder who is responsible for its use. To benefit from electronic toll payment in your different vehicles, you can order an extra holder or extra badge in one of our agencies in France or in your subscriber area .

However, you must make sure you take the right electronic toll payment lane for your type of vehicle
