When you change the number on your vehicle in Delaware, you get a new title, with the new number on it, as well as a new registration certificate with the new number on it, so we are talking about all three, title, registration certificate, and tag. Oh yes, I forgot, even the sticker has the same number on the bottom it, and it matches the tag number. They all match. If you don't believe me, check your own titles, tags and registrations. I have changed tag numbers, and this is what I have gone through. He also, must have the titles. He doesn't have a title, he can't do it! Get caught driving that van in Delaware, he will have more to worry about than insurance. He is now driving a vehicle that is unregistered and displaying a fraudulent tag, as well as having no insurance.........
