Where do I get my physical USDOT number after it's issued?
Short answer: nobody mails you one. The FMCSA issues a number, not a sticker. Once your USDOT number is active you are responsible for getting it lettered on both sides of every power unit yourself. That is the part we do.
What the FMCSA actually sends you
When your registration is approved you get a number and a record in the FMCSA system. There is no decal, plate or placard in the envelope, and there is no government-issued marking to order. Sign shops, vinyl shops and truck-lettering companies make the physical marking, and any of us can, as long as it meets the federal marking rule.
What the marking has to show (49 CFR 390.21)
The federal rule for marking commercial motor vehicles, 49 CFR §390.21, says the marking must appear on both sides of the vehicle, show the legal name or a single trade name of the motor carrier exactly as it appears on your MCS-150, and show the USDOT number preceded by the letters "USDOT". It has to be in letters that contrast sharply with the background and be legible from 50 feet in daylight while the vehicle is stopped. The rule does not name a font, colour or exact letter height — 2-inch letters in a plain block font are the industry standard because they clear the 50-foot test on a truck door.
Our kits are cut to that standard: legal name and USDOT number, one set for each door, 3M cast vinyl in a contrast colour you pick against your truck colour. If you carry an MC number and want it under the USDOT, add it in the order fields — it is included at no extra charge.
Two ways to get it on the truck
Ship it and apply it yourself — $110, free shipping. You get both door sets pre-masked on transfer tape with a squeegee and instructions. Applying it takes about ten minutes a door. Order the USDOT + MC number kit.
We install it in Spokane or North Idaho — $195. Both doors applied by us, proof approved first, then we schedule. Book the installed USDOT lettering.
What we need from you
Your legal name exactly as it is on the MCS-150, your USDOT number, your MC number if you display one, and the colour of the truck so we pick a vinyl that contrasts. Every order gets a proof before anything is cut, so a typo never makes it onto a door.
Common follow-up questions
Do I need a new marking if I change my company name? Yes — the name on the truck has to match the name on file with the FMCSA. Update your MCS-150 first, then reorder.
Does it go on trailers too? The rule applies to the power unit (the truck or tractor). Marking trailers is optional unless a state or your lessor requires it.
Can I use a magnet? The rule does not prohibit removable markings, but inspectors and insurers routinely ask for permanent lettering, and a magnet is the first thing a roadside officer questions. Vinyl costs about the same and stays put.
