Indeed.
"Mille un" and "mille onze" which is much easier than "un zero zero un".
Similarly I don't understand why in english we couldn't use "thousand one" and "thousand eleven" which is much clearer than a jolt of zeros and ones.
Separation number by number is only used as a way of disambiguation, in a very slow manner.
