Upgrade to C permit, whom should I inform?

I should have seen this topic in the forum before, but cannot find it. Quite sure that the car insurance is among the list, not sure about the others. Many thanks .

Hi moderator, please delete this thread, thanks.

If you become Swiss your car insurance may be reduced, I don’t believe it happens with a C.

Your employer, particularly if they assist with permit renewals,

Your Commune, unless they were involved in the process,

That’s about it.

Sorry, my bad. yes, the discussion i saw is was about becoming Swiss... Will ask the moderator to delete this thread

I’ll close the thread for you.

We never informed anyone when we moved from a B to a C permit. The info seemed to be transmitted to the people who needed to know automatically.
