The correct way to say 1 000 001 in French is indeed "un million un". I do hear sometimes "un million un" for 1 100 000. It may come from "1.1 millions". It is incorrect and as we say in French it is "un abus de langage".

To be sure people understand what I meant, I would say "un million et un".

1 000 000 : "millionième", 1 000 001 : "million-et-unième"
