Do you need a DOT number for a cargo van? The 10,001 lb line
The federal line is 10,001 pounds
Under 49 CFR 390.5T, a commercial motor vehicle is a vehicle used on a highway in interstate commerce to transport property or passengers that has a GVWR or GCWR, or actual gross weight or gross combination weight, of 10,001 pounds or more, whichever is greater. It's also a CMV if it hauls hazardous materials in an amount that requires placards. Interstate carriers of CMVs file an MCS-150 and get a USDOT number (49 CFR 390.19T), then mark the vehicle (49 CFR 390.21T).
GVWR is the manufacturer's maximum loaded weight for the vehicle. It's on the label in the driver's door jamb. It's not what the van weighs today.
Where common cargo vans land
Weight ratings vary by model, wheelbase and package, so read your own label. Two examples from 2026 model listings:
- Ford Transit-150, 148 in. medium roof: 8,800 lbs GVWR (cars.com spec listing). Under the line.
- Ford Transit-350 HD cargo van: offered with a 9,950 lb GVWR and, on the High Roof Extended Length DRW, an 11,000 lb GVWR (KBB spec listing). The 11,000 lb version is a CMV on its own in interstate commerce.
Towing changes the math
GCWR counts. 390.5T defines it as the greater of the maker's GCWR on the certification label, or the sum of the GVWRs (or actual weights) of the van and whatever it's towing. The maker's GCWR is not used when the van isn't towing.
Example: a 2026 Transit-350 with a 9,500 lb GVWR lists a 10,800 lb GCWR (cars.com spec listing). Hook up a trailer for work in interstate commerce and you're over 10,001.
Under 10,001: no federal USDOT marking, but check your state
A cargo van under 10,001 lbs GVWR, not towing, not hauling placarded hazmat, isn't a federal CMV, so the federal USDOT number and door marking rules don't reach it. Some states set their own rules for intrastate carriers, so check our state rules page and intrastate vs interstate USDOT. Operating authority (an MC number) is a separate question; see USDOT vs MC number.
Lettering a van
Van doors are smaller, so our Small size (1.5 in numbers) is the usual fit; see size requirements. USDOT truck lettering starts at $59 for both doors. If you only need a name and phone for a delivery van that isn't a CMV, printed door magnets are an option.
Related questions
Does a Ford Transit need a DOT number?
Depends on the version. A 2026 Transit-150 rated 8,800 lbs GVWR is under the line on its own; a Transit-350 HD rated 11,000 lbs is over it. Check the door jamb label and whether you tow.
I deliver packages in a van under 10,001 lbs. Do I need a USDOT number?
Not under the federal CMV definition if you aren't towing and aren't hauling placarded hazmat. Your state may have its own rules, so check.
Does my trailer count toward 10,001 lbs?
Yes. When you tow, the GCWR, including the sum of the van's and trailer's GVWRs, is used, and whichever weight is greater controls.
Where is the GVWR on my van?
On the manufacturer's certification label, usually in the driver's door jamb.
