Sigma Serial Numbers Lens
Canon Lens Serial Numbers
Now that the main question has been dealt with, does anyone know if there is a pattern to location of the serial number? It doesn't seem to be chronologically determined, at least. On some of my Canon lenses, both recent origin and early lenses still in the list, the number is on the metal (or plastic) base plate, as in the case here.

On some others, similarly both recent origin and early lenses still in the list, it is stamped into the lens barrel on the bottom near the mount, with or without paint.
The lens I received is a XXmm f/XX lens for my XXXXX brand camera, and has serial number #233XXXX. The lens you received has a serial number which has not been issued by Sigma’s factory in Japan. It appears that the lens you received is a 'Gray Market' lens, and has been tampered with having its serial number changed.
