From the top voted answer on "What exactly is a 'CV'?":
In most contexts, CV ( Curriculum vitae ) and resume are used interchangeably. Different countries and different industries tend to prefer one term over another. An academic job in any country will typically ask for a CV, a non-academic job in the United States will typically ask for a resume, other countries (such as most European companies) will prefer the term CV. In most cases, everyone is talking about the same thing.
I haven't found a resume question insofar that specifically asks about resumes instead of CVs (haven't looked that hard though), I think they are used interchangeably and we should make them synonyms. And although it might go against the tags' question count, I'd propose CV as the master tag, as it's the most recognizable term of the two (worldwide).
I'm of the opinion that they should be separate and the resume tag wiki should no longer refer to CVs.
Why?CVs are generally rarer and more specific
Resume only applies to the US, my CV is a resume.
