Interesting question. I haven't researched the issue, and while I think rlcarey's comment make sense, I could also see an argument that you would report it.
I believe that the NMLSR has a technical "inactive" status that you can be put into for not paying fees etc. When you pay your fees, your ID is reinstated or activated, using the same number. Similarly, if you were a lawyer, your state bar licenses number is unique to you, whether its active or not. In that case, so I could see any argument that reporting it in that case is still valid (especially knowing the CFPB is keen to have as much data about a transaction as possible).
With that said, I suspect if you just pick one approach and stick with it you'll be find during an exam.
My opinion, take it for what its worth. Opinions expressed are my own and not those of my employer and are not legal advice.
