Do I have to put my company name on the door, or is the USDOT number enough?

The number alone is not enough. The federal marking rule asks for the carrier’s legal name or a single registered trade name as well as the USDOT number, on both sides. Plenty of trucks run with the number only and it is one of the easier things for an inspector to notice.

How big do the letters have to be?

Federally, there is no minimum height. The standard is contrast and legibility from 50 feet in daylight with the truck stopped, and it applies to the whole marking. Illinois is the exception people trip on: for intrastate carriers the state rule specifies at least 2 inches high and 1/2 inch wide, with a smaller spec for vehicles under 9,000 pounds. In practice we size the name so it reads comfortably from a lane away, which clears both.

Can I use a shorter version of my company name?

Only if that shorter version is the single trade name you are registered under. The door has to match the record, so "Northwind Carriers LLC" on the filing cannot become "Northwind" on the door just because it fits better. Bring the paperwork and we lay out what it says.

What else should go on the door besides the name?

That is up to you, and it is the part the rule leaves alone. Most owner-operators add a phone number, and it is the single highest-value thing you can put there — a truck parked at a dock is an advertisement. City, website and a short line about what you haul are common. What we push back on is crowding: four lines of small text read as nothing at all.

Can you match the lettering on my other trucks?

Yes, and that is worth doing in one place. Send a straight-on photo of an existing door and we will match the letterform, spacing and position closely enough that a new truck parked beside an old one does not look like a different company. We keep the artwork so the next unit matches too.

Will taking it off later damage the paint?

On factory paint in sound condition, no. Vinyl comes off with heat and patience and the adhesive residue wipes away. What does lift is paint that was already failing — a repainted panel that was not prepped, or clearcoat separating on its own. Tell us if a door has been resprayed and we will treat it as the fragile surface it is.

How fast can I get lettered?

Most door sets are cut the same day at our Rolling Meadows, IL shop, and a standard pair goes on while you wait. Call ahead so the layout is ready when you arrive instead of starting from a blank screen with you standing there.

What does truck lettering cost?

It depends on how much goes on the door, whether it is cut vinyl or printed, and whether you want an outline or lamination. Call or text what you need and you will have a price in minutes.

Truck & Door Lettering

Truck lettering is your company name, phone number and web address cut in outdoor vinyl and applied to the cab doors — the part of the truck a customer reads at a light and an inspector reads at a scale. It also carries the half of the federal marking rule people forget: 49 CFR 390.21T asks for a name as well as a number, and the name has to be the legal one you are registered under. We lay out both together at our shop in Rolling Meadows, IL, usually cut the same day, and ship anywhere in the US.

Where it lands from there depends on the job — size, cut vinyl or printed, an outline, lamination. Call or text and you have the number in minutes.

SHORT ANSWER

Bring or send your legal business name exactly as it appears on your FMCSA registration, plus anything else you want on the door — phone, website, city, a slogan. We lay it out to read from a lane away, cut it in outdoor vinyl in a color that contrasts with your paint, and hand it over pre-masked with a free squeegee. Most door sets are cut the same day in Rolling Meadows, IL.

What you get

Your legal business name or single registered trade name, laid out to the federal legibility standard
Phone number, website and city sized so they read without crowding the name
A layout that fits your actual door — measured or worked out from a photo, not a template
Color matched to contrast sharply with your cab paint, checked before anything is cut
Outdoor-grade cut vinyl rated for years of sun, salt and washing
A matched pair, because the rule asks for both sides and one door is never enough
Pre-masked on transfer tape so it goes on as one piece, not thirty letters
A free squeegee and the install guide, plus a hand with the install if you are at the shop

What actually has to be on the door

The federal marking rule is short, and most of what people believe about it is not in it. Here is what 49 CFR 390.21T says, and what it does not:

A name and a number, not just a number. The rule asks for the carrier’s legal name or a single trade name, alongside the USDOT number. A door with the number and no name is only half marked.
The name has to match the paperwork. It must be the legal name or the single trade name the carrier is registered under with FMCSA. A shortened version somebody liked better does not satisfy it.
Both sides. The marking goes on both sides of the vehicle. There is no version of this rule that a single driver-side door satisfies.
Sharp contrast, legible at 50 feet. The standard is colour that contrasts sharply with the background and legibility in daylight from 50 feet with the truck stationary — and it has to be maintained that way, so a faded set stops complying before it falls off.
No federal letter height. The rule sets no minimum character height. Anyone quoting you a federal inch measurement is repeating an industry habit, not the regulation. Illinois intrastate work is different — that one does have a number.
Leased trucks carry the operating carrier. If you run under someone else’s authority, the door shows their legal name and their USDOT number, not yours.

If you run only inside Illinois, the federal rule may not be the one you answer to at all — the state runs its own marking requirement under 92 Ill. Adm. Code 1307, and that one does specify character size. Bring your registration and we cut what your paperwork actually says rather than what is most common.

How ordering works

1
Send us the name
Call, text or use the quote form with your legal business name as registered, plus whatever else goes on the door. A straight-on photo of the door helps with sizing and colour.
2
We lay it out
We set the type, size it against your door and check the colour against your paint. You approve the layout before anything is cut.
3
Cut and masked
Cut in outdoor vinyl and pre-masked on transfer tape, so the whole line goes on together and stays spaced the way it was laid out.
4
Pick up, install or ship
Most sets are ready the same day in Rolling Meadows. Installed while you wait if you want, or shipped anywhere in the US with the guide and a squeegee.

Design it yourself Read the install guide

Usually ordered with it

US DOT number decals

The other half of the same rule. Nearly everyone orders the name and the number together, because a door needs both.

Magnetic signs

For a truck that goes back to being a personal vehicle on the weekend, or a lease that has to come off clean.

Trailer lettering

Unit numbers and company name for the trailer, which carries no federal carrier ID of its own.

Fleet apparel

The same name and logo on shirts and hoodies, laid out from the same artwork.
