I am French and I have a national ID card that expired recently. France extended the validity of this card and it is now valid for 15 years (instead of 10).
Many European countries (the EU I think) accept national IDs of European citizens as a valid ID.
I am worried however that my expired national ID will not be accepted during my trip. I would like to know which countries accept expired national French ID cards (expired less than 5 years ago) and in particular if Germany, Switzerland and Italy do accept these cards.
