In the state of Michigan and Ohio, we get new tags every year ( lately the tags are just a sticker). Are plates go for a long time anymore. The State gets a whim every now an than and we get new metal plates. As said before they used to be different every year.
The tags in Michigan DO NOT follow the car.
If you have an older car and find an older plate of the year of your car it can be you can get that registered if nobody has that number , but you will have to pay for a new plate and keep it in your car while driving it ( I have been told this is how it works).
In 1976 Michigan had the red white and blue plates . They went to a black plate in 79 . then a few years later ( 82-84) they went with a blue plate that we used past 1990 .
