That's a WBCCI club membership number. It is assigned to members who put them on their trailers. It's your trailer now and sounds like the former member's numbers were not removed.
There's a thread in here somewhere where you can provide those numbers and find out who had them and if they're still available, you might be able to get them assigned to you if you become a WBCCI member.
