Documented boats require the official # to be permanently marked on a structural part of the hull. I'm thinking somewhere in the bilge would be best. What method is typically used is make this "permanent" mark? The previous owner does not appear to have done this as I can't find it.
 
I had the same issue when I purchased my used vessel. My shipyard used a block of wood and carved the numbers into it, then used a bonding adhesive to permenantly affix it on the back wall inside the bilge.
 
Stencil and paint on any accessible stringer. About $10 total. Mark where you placed the numbers on your documentation papers. If boarded, you won't remember. DAMHIK!

I did them same as this, but I used boating numbers from West Marine and covered them clear epoxy.
 
Use a router to engrave 3" high numbers on a bulkhead in a storage chamber beneath a salon hatch.
 
I heard back from the Power Squadron inspector and they said they would also accept permanent marking pen on a structural part of the hull. That surprised me, not sure I'd go that way. Thanks all, as usual, all the answers are on CSR.
 
I just used spray paint and stencil numbers from West marine. The coast guard regulations have this listed as an option.

I have a 280, so the bumper storage locker on the stern is a great place. Also, the storage under the bow V-Berth is great too. My engine room is too crowded to be able to paint something, but most 280's I have seen will use the engine room.

The great thing about the stern locker is that you can display it without boarding the vessel. Further, if you did happen to look for a stolen boat, it would be the easiest place to check.
 
I just got some stick on numbers at Walmart and sprayed clear paint over them. Located on the underside of the swim platform as seen from inside the engine bay. Just open the engine hatch and they are visable.
 
I had the numbers come with my documentation, black 3 inch with adhesive backs. With this discussion I'm not sure if maybe that's something the dealer threw in.

I went to West Marine and got a small bottle of clear apoxy. I but the numbers in the engine room on the bottom front of the swim platform which is open at that point. It is smooth and as soon as your open the hatch you look straight at them. I brushed the apoxy over them and they are permanantly sealed, 10 minute job.

Don't forget the NO is part of the number.

I put the decal type numbers from Lowe's hardware store on my starboard stringer behind the engines. I then painted a thick coat of fiberglass resin over the top of them. It is a clear finish and would require obvious damage to remove them. The Power Squadron thought it was great and it took about 5 minutes to do.
