For my resume I would like to say something like "acting as the unofficial Communications Director". Which is true, but my official title was something else. Is there a better word than unofficial that describes performing a job function without holding the title?
The term I would use is "de facto".
The definition is: Exercising power or serving a function without being legally or officially established. Examples: a de facto government; a de facto nuclear storage facility.
So you were a "De Facto Communications Director"
How about a Volunteer Executive Communications Director?

I think you want to keep it simple on a resume. Actually, you may omit ‘unofficial.’
You could say:
In addition to my responsibilities as a / the ___________, I also performed (many of) the duties of the Communications Director.
In addition to my responsibilities as a / the ___________, I also acted as the Communications Director.
Regarding the latter, if anyone asks, you can explain it. ‘Acted’ does not imply that ‘Communications Director’ was your job title.
