Serial numbers are stamped into the frame. It could be in several places, like under the crank, on the rear part of the frame on even on the front tube. It may also have been ground off, as with a stolen bike. Give the bike a once over carefully, if you don't find it, don't worry just ride it or go to a autobody shop, they have the stamps to make up your own.
