It is known that the option num:nil drops the numeration of sections (when exporting from org-mode), but

How could I include a unnumbered section among numbered ones in Org-mode?

You can turn off numbering for a section by adding the property :UNNUMBERED:. i.e.:

* Heading 1  
* Heading 2, unnumbered  
  :PROPERTIES:  
  :UNNUMBERED: t  
  :END:  
* Heading 3

Update 19 August 2020

As a commenter is suggesting that I'm lying about this for some reason, here is the output from exporting a file containing the above snippet, and nothing else:

enter image description here

Exported via C-c C-e l o (i.e., org-export-dispatch)

  • Emacs 28.0.50
  • Org 9.3

This also worked when I first posted this answer in 2017, using whatever the development version of Emacs was at that time.

As you can see, Heading 1 and Heading 3 are numbered (and as such included in the TOC), and Heading 2 is not.

If that doesn't work for you, please provide some details or ask a new question.

  • This does not work for me. Would you know why? – Diogo Mar 1 '18 at 19:18

    @diogo based on the information you have provided, no – Tyler Mar 2 '18 at 22:37
  • Nor me. Just try it. There are no auto numbers in the example so we don't even know if it worked for Tyler – RichieHH Aug 18 at 19:44
  • @RichieHH if you don't provide any details, there's no way for us to figure out why it doesn't work for you. It does work for me, and at least the six people who upvoted the answer. – Tyler Aug 19 at 14:21
  • Thank you it worked, but is there a way to remove numbering from every section heading without adding these lines everywhere? – dark32 Sep 22 at 10:07
