I just checked the serial number on the box, which I was using to try to register, against the serial number on the bottom of the soundbar, and the number on the product has an extra digit, in my case an extra letter N. After entering this it let me register the serial number.

In case you decide to have another go. I used https://www.samsung.com/uk/mypage/ and it worked in the end, with the full serial number from the bottom of the actual soundbar (the number on the box is a digit short.)
