It's an ADVERT for their APP and a very expensive Crit Air Badge.
I had all sorts of fun getting the right one. If you go to the
https://www.certificat-air.gouv.fr/en/ and then find the tab ' SIMULATION ' you can put your vehicle details in and sort out what it's supposed to be. At the moment I have 3 different ones. First attempt came back as a 4. Following their instructions I finished up with a 5. Now have the correct one a 2. What a load of mucking and messing about and what a crap site. Why don't they take you to the SIMULATION bit first or at the very least when you have filled everything in tell you what you are going to receive and let you decide with either a Yes or No. To simple for the French.
One tip don't fill in the Euro number as we don't have one on the V5. I filled in Euro 5 and it makes a right mess. All you need is the date of first registration and let their system work it out.
