Look very, very closely, if theyre like my 16-35mm f/4 then its very, very lightly etched into the lens quite near the lens mount, it needs to be looked at in the right light or cant be seen

Nikon 18-200mm: The serial number is etched into the lens barrel, diametrically opposite the focus window.

Nikon 17-55mm f/2.8: I've got 4 of them coming in tomorrow so I'll be able to tell you then if nobody else has.
