About this plate
The permanence is worth noting against the file-level ten-year renewal bar, a plate that is never renewed cannot be caught by a bar on renewal, so the trailer plate escapes Michigan's own lifetime rule by construction. That interaction is the kind of thing a claims model should be able to express.
How numbers are issued
observed D000000 to F134612 as of October 2024 (secondary)
How long it is valid
PERMANENT, the legend says so on the plate itself, which makes this a series whose end condition is the vehicle's, not the year's
