I do not speak French, so I write in English.
I translated to Spanish the help article https://en.numista.com/help/what-is-the-n-number-visible-in-the-catalogue-33.html and I saw that in the French version https://fr.numista.com/help/qu-est-ce-que-le-numero-n-visible-dans-le-catalogue-33.html this paragraph is missing:
The N# contains only digits. Unlike some other reference numbers, it is not sequential and it doesn't convey any logical information; also, the N# numbers don't repeat for different countries or periods. The only purpose of the N# number is to have a permanent, immutable, and unique identifier.
