However, there are some exceptions to this rule. For example, when used in dates or telephone numbers, numbers under 10 may not be spelled out. For instance, the date "September 1, 2023" would be written as "1er septembre 2023" instead of "un septembre deux mille vingt-trois."
Additionally, compound numbers above 16 (as well as some exceptions below) aren't spelled out entirely. For example, the number 23 would be written as "vingt-trois," not "deux trois."
