That's true, but you have to be sure that the S/N is actually an existing number. Some companies keep records of the location of the item (or at least the country). This might give issues when you have a serial number from the USA but order something in Europe.

Also it should be properly edited, not copy-pasted in MS-PAINT, cause they WILL notice that!

Ofcource, shouldnt be a half arsed job.
