Where is the serial number on my Shaun White Burton Snowboard? - serial number from mount and blade

I bought in recent years, the series of AKA White Burton Snowboard Shaun White. I try to register a report on these things snowboarding, if stolen. However, I can not find the serial number. My old board is equipped with a serial number between the union, the assembly is on the edge of the plate. I checked and I checked the whole board, but I can not find him. Is the correct serial number in the mounting holes? I will not delete the links when necessary. The label contains the serial number, but I just want to know where the serial number is on the board itself.
