Serial number worn off on EOS Rebel T4i

[SingingDrummer]

There is a serial number sticker on the bottom of my camera - but the number that was on there at one time is worn off.  Is there anywhere else I can get the serial number?  Support won't let me enter a ticket without a serial number.  Thanks

The serial number is embedded in each image the camera captures. Simply take a screenshot photo and then open it in Canon Digital Photo Professional (DPP) show the Info about the image and there you will have the serial number.
