Nevada DOT Number Requirements: CPCN and MV Numbers on the Door

Nevada DOT number requirements have two layers. The marking rule in NAC 706.170 puts the carrier's name on the side of the power unit and, for carriers under the Nevada Transportation Authority, adds the letters CPCN with a certificate number, or MV with a permit number. Separately, the Nevada DMV says a USDOT number is needed even for Nevada-only trucks that weigh 26,001 pounds or more. This page takes the two layers one at a time.

Layer one: the state marking in NAC 706.170

The rule is short, and its pieces apply to different carriers. Here is how we read it.

• Common and contract carriers in intrastate commerce: the name of the carrier goes firmly on each side of the unit that has the engine, in letters "not less than 2 inches high" in "sharply contrasting colors which are legible from a distance of at least 50 feet."
• Private carriers in intrastate commerce: the same name rule, except for single-unit vehicles with an unladen weight of 10,000 pounds or less.
• Carriers under the Authority's jurisdiction: the symbols CPCN and the certificate number, or MV and the permit number for a contract carrier operating under a permit, painted or affixed on each side of the power unit, in the same manner, size and style as the name.

The 2 inch figure is Nevada's, and the rule gives it for the name. It is not a federal number, and our decal widths of 12, 18 and 24 inches are not letter heights. Read the current text at NAC 706.170 before you size anything.

What CPCN and MV stand for in practice

The rule uses the letters as symbols and does not spell them out. For-hire hauling in Nevada is licensed by the Nevada Transportation Authority, which is where a certificate or permit number comes from. If you are not sure whether your hauling is under the Authority, ask it. Nothing in the rule text says that an ordinary work truck carrying its owner's own tools needs a CPCN or MV number, so private carriers should read the second bullet above and ask.

Layer two: the USDOT number

NAC 706.170 does not mention a USDOT number. That comes from the federal side, where the marking rule asks for the carrier name and USDOT number on both sides of the power unit, in colors that contrast sharply with the background, readable from 50 feet in daylight while the vehicle is stopped (49 CFR 390.21T).

For trucks that stay in Nevada, the DMV motor carrier page says: "You must have a USDOT number even if you only stay in Nevada, provided your vehicle weighs 26,001 lbs or more" (Nevada DMV). We did not read a lower threshold, so for a lighter truck ask the DMV. Our USDOT number checker walks through the usual questions.

A sample door

Take a made-up carrier, Silver Mesa Hauling, which holds a made-up certificate numbered 4567 and drives a single power unit around Clark County. A door built from the rule would read:

• SILVER MESA HAULING
• CPCN 4567
• USDOT 1234567

A contract carrier working under a permit would swap the second line for MV and its permit number. All numbers here are invented. Slips to check for:

• CPCN or MV left off the door of a carrier that is under the Authority.
• The number copied from the wrong paper. The certificate or permit number is not the USDOT number.
• A name that does not match your Authority records or your federal registration.
• Letters too small. Stand 50 feet away, in daylight, and read every line.
• Only one side done. The rule says each side.

Our examples and mistakes guide covers more of these, and company name on truck requirements explains where the federal name rule comes from.

Lessees and removable signs

Two details in the rule are easy to miss. A lessee running a power unit under a short-term or long-term lease must paint or affix its own name and number on the vehicle. And any removable sign or placard must be made of a durable material such as wood, plastic or metal, must carry a serial number from the carrier's own series, and the carrier must keep a record of each number. If you plan to use removable signs, ask the Authority how it wants that record kept. Our leased-to and operated-by guide covers the federal side of leased trucks.

Where the numbers come from

• USDOT number: applied for with FMCSA in its Motus system at motus.dot.gov. Our guide to getting a USDOT number covers the steps.
• CPCN or MV number: issued through the Nevada Transportation Authority. We did not read its application steps, so ask the Authority.
• Nevada-only registration and the intrastate application: the DMV describes its own process on the motor carrier page linked above.

Questions to ask Nevada before you print

1. Is my hauling under the Transportation Authority, and if so, is my number a CPCN or an MV?
2. Does my private truck fall under the unladen weight exception?
3. Does my truck need a USDOT number at its weight?
4. Does anything else belong on the door for my kind of work?

Write down the date and the name of whoever answers.

Ordering a Nevada decal

The Nevada CPCN / MV Number Decal with Carrier Name prints the carrier name and the CPCN or MV line you type. It starts at $22.99 per decal at 12 inches. For the USDOT line on its own, the USDOT Decal Sticker is $18.99 at 12 inches, and the Company Name + USDOT Decal is $27.99. Preview the lines in the door builder. We print the words and numbers you type, and you answer for the content, so confirm everything with the state first. For how other states differ, see USDOT number requirements by state.
