DOT Number Stickers for Trucks

DOT number stickers are made-to-order vinyl decals that put your USDOT number on the truck door, and Work Decals sells them from $12.99 per decal. Pick the number-only decal if your company name is already on the door, or a longer layout if you want the name, MC number or city on the same sticker. Order two, one for each door, and apply them yourself.

What the federal rule asks for on the door

The federal marking rule, 49 CFR 390.21, asks for the carrier's legal name or a single trade name, and its USDOT number preceded by the letters "USDOT", on both sides of the truck. The letters must contrast sharply with the background and be readable from 50 feet in daylight while the vehicle is stopped.

Nobody pre-approves a decal. It carries whatever you type, so you are responsible for the name and number. Rules change. Our plain-English display rules cover the rest, and FMCSA's Do I need a USDOT number? page says whether your truck needs one.

Which USDOT decal should you pick?

Prices are per decal.

USDOT Decal Sticker, $12.99

Your USDOT number and nothing else. It suits a truck that already shows the company name, and it is our lowest-priced USDOT decal. See the USDOT Decal Sticker.

USDOT + MC two-line, $16.99

USDOT on the first line, MC on the second. FMCSA says no federal marking requirement exists for an MC number on a truck, but many carriers add it anyway. Unsure what MC covers? Read MC number vs USDOT number, then see the two-line decal.

Company Name + USDOT, $21.99

Your name above your number: the two items the rule names, on one sticker. See Company Name + USDOT.

USDOT / MC / CA / GVW four-line, $22.99

A tall stack for carriers whose state asks for more than the federal rule. Swap any line for KYU, TXDOT or a VIN. Check requirements by state first, then see the four-line decal.

Custom USDOT Logo, $26

Name, city, USDOT and MC together. FMCSA says the rule neither requires nor prohibits the city. Despite the name, this is lettering, not a drawn logo. See the Custom USDOT Logo.

What to type on the decal

• The number: write "USDOT 1234567", letters first, because the rule asks for the number preceded by "USDOT".
• The name: use the legal name or single trade name as listed on your FMCSA registration (Form MCS-150).
• A check: compare the digits with the free SAFER Company Snapshot (how to look it up).
• A second look: we print exactly what you enter, so read the preview before you pay.

Colors and widths

Choose a sticker background from White, Black, Yellow, Silver, Red or Blue, and lettering in Black, White, Red or Blue. The lettering sits on the sticker's own background, so that pair is the one to get right. Black on white or yellow, or white on black, are plain high-contrast choices; the door builder warns when a pair is hard to read.

The 12, 18 and 24 inch options are decal widths, not letter heights. The federal rule sets no height, only the 50-foot test. Compare widths in the door decal size guide and how big USDOT numbers need to be.

How many to order

Both sides means one decal per door, so order 2 per truck; the product pages start at quantity 2. The rule covers the self-propelled vehicle, not a towed trailer, per FMCSA's 2000 final rule, so a fleet needs a pair per truck. The rule does not set a spot on the door: see where to put the USDOT number.

Shipping, installing and the guarantee

Shipping is $5.99 flat per order, or free at $99 and over, counted before any discount. A pair of Custom USDOT Logo decals is $52 and pays shipping; four for two trucks come to $104 and ship free. Tracking is emailed one to two days after you order.

Installing is DIY: a printed instruction sheet and a video link come in the package, and the video is on our install page. A 3-year guarantee covers a free replacement if a decal peels or comes off (refunds and returns).
