Nice thing about caps is they are almost never labeled, so you can "counterfeit" by merely swapping labels on the reel, or stock numbers even.
Ditto for voltage. You could get an 0805 10nF that's 16V (contains a few very closely spaced plates, and a lot of unused ceramic), or 100V+ (the entire height is filled by more, and widely spaced, plates). No idea until you do a C(V) test.
