Behind the SIM flap is a plastic information sheet that can be pulled out. The production week and year, for example, are indicated by something like "14W38" (that's what's on mine) which means that my unit was manufactured in the 38th week of 2014. I'm not sure about the serial number though. I just looked and there's no immediate "S/N" indication. However there is a big number after the "CE" sign, for me it says "CE 0682". Maybe that is the number of the production batch?
