Validated until April 2023 when renewed at Secretary of State, however kiosks continue to print out new tabs.

Since September 2000, special plates have been offered to raise funds for each of Michigan's 15 public universities.

[13] State law limits the number of fundraising plates (excluding universities) available at one time to 20, and 14 are currently in production.
