Usages
The numero sign, despite its widespread usage internationally, is not a standard alphabetic symbol in virtually any European languages. For example in English, the abbreviation "No." of "numero" is often used in place of the word "number". In US English the number sign, "#", is frequently used instead. In German, the abbreviation for Nummer is "Nr." (with full stop), whereas in Finnish the abbreviation for numero is "nro" or somewhat archaic "n:o" (to distinguish it from a plain no, which is an exclamation roughly corresponding to the English well in "Oh, well" or "Well, let's see").
