If your getting a custom ( Any board not just a SUP) get the shaper to write your license number on the stringer with the measurement. Easy way to identify it, not sure how you could do it on a popout though
Its a bugger if you sell your car tho. I guess its like a ID number in a way.
I take pics of all my boards when I get them, that way if they do go missing I have some evidence.
