I am posting this because I have seen several threads on this and it seems there is always several different answers. This is what I went through. When I built my car I removed the VIN tag in the dash to replace some metal and fabricate a new dash panel. Well, by dumb butt lost the darn tag. So I completed the build. The title matched the body stampings, so I figured I would be OK. I got talking to deputy sheriff at a car show and he questioned me about the missing tag. I told him the story and asked him if he wanted to match the registration numbers to the body stampings. He said no, he believed me. However did say that the next LEO that notices it might not be so understanding. That my car could be impounded until the matter was cleared up. Oh crap my baby in impound, car jail. Yikes! The deputy told me to go to the Department of Motor Vehicles and see about a replacement tag. So off I went, and stood in a 45 minute line to talk to somebody that clearly didn't want a complicated problem to deal with on a Friday. After the DMV conversed with her boss for about 10 minutes I was sent to another office. The office of Department of Motor Services. Hmmm, never heard of them. So, following the instructions I found this little hole in the wall office burried amongst the other government offices. The lady at the DMS office asked me if I had a clean title for the car, which I produced and showed her. She disappeared into a cubical for a few minutes and came back, telling me that I will need to bring the title back along with the car so they can look for the "Hidden VIN" and match it to the title. Then they would fill out a form and send it to Tallahassee where they would issue me a new/replacement VIN. She told me the replacements are special stickers that they[DMS] will put on the car. After bringing my car to the DMS office and getting it authenticated, I just got a call that my new VIN was in and to bring the car back. So I loaded the hotrod on the trailer and took her back. This is what I got. A sticker in the windshield And one in the door frame. Which has HSMV (Highway Safety and Motor Vehicles) on it and neither DMV or DMS. Governments and their acronyms are mind blowing. The best part of it all was the cost...........FREE! That surprised me. The lady noticed and explained that the DMV/Tax collectors offices are county run(even though they issue licenses and plates ) and the DMS is state run. This is how it is done in Florida. I cannot say for other states.
