Why You’ll Never See License Plates on Mail Trucks in Rochester
If you've ever noticed any U.S. Postal Service vehicles here in Rochester, have you noticed they never have license plates? Here's why that is.
The Mystery of Missing License Plates on Minnesota Mail Trucks
License plates here in the Land of 10,000 Lakes have been in the news recently, with the increasing popularity of both the Minnesota Vikings plate and Minnesota's two-year-old blackout license plates that are now available.
Every car, truck, van, or sports utility vehicle that's kept here in the North Star State is required to display a front and rear license plate issued by the Minnesota Department of Public Safety, Driver and Vehicle Services Division. Even motorcycles, recreational vehicles, and even trailers are all required to display a Minnesota license plate. But THESE vehicles don't have to.
You might have noticed delivery vans that the U.S. Postal Service (USPS) put into service in Rochester a few years ago. I noted our mail was being delivered from one of these Dodge Ram vans back in 2024. But I also noticed that the USPS van conspicuously did NOT have a Minnesota license plate on it.
Why Federal Law Exempts USPS Vehicles from State Plates
Curiously, the older-style vehicles the USPS also drives also don't sport any type of Minnesota license plate either, though I guess I never really noticed before. I'm guessing that's because on the new Ram vans (above) there's a distinct license plate holder located on the left rear door, with the familiar blue and white Minnesota license plate conspicuously missing.

That 'missing' license plate appears to be way more inconspicuous on the older-style USPS vehicles (below), which don't sport any type of license plate holder on the front or back.
And, just last year, the USPS introduced those weird-looking delivery vehicles with the huge windshields on them. Officially, they're called the NGDV-- which is short for 'Next Generation Delivery Vehicle, and they don't have any license plates-- or license plate holders either. (You can find out more about those NGDVs in the video below.)
How Mail Trucks are Identified Without a License Plate
So just WHY don't any USPS vehicles have Minnesota license plates on them? Well, according to this WKTY-TV story, it's because of a federal law passed 50 years ago, back in 1973, that exempted any USPS vehicle from having to display any state license plate.
You'll note, however, that each USPS vehicle does contain a unique number affixed to it, which serves as a way for each vehicle to be identified. And, this 6-News/Orlando story noted that while they're not required to have license plates, those USPS vehicles are still required to have insurance-- and anyone driving them is still required to obey all traffic laws.
