Where do you find the serial number on a GA-G31M-ES2L?

I cannot seem to find the serial number on the actual board. I have two boxes for this mobo, and the box has the serial number, but I have no idea which one goes with the board.

Wild guess, but last Gigabyte mobo I saw had the sticker on the side of the ATX power connector (i.e. off the PCB).
