There’s no reason it couldn’t be real. The only requirements for N numbers are listed here:

What is the meaning of the first two digits in these (and other) tail numbers? I've never seen any rhyme nor reason to them. Theye almost seem like check digits.
I was under the impression that UA simply scoured the registry looking for values that were available and would match the internal tail designator. So if it’s tail 999, they’d look for Nxx999 and see what’s available. That may be an oversimplification on my part, but I agree that there doesn’t seem to be rhyme nor reason to them.
