What a USDOT number is

The U.S. DOT number is the key to a company’s federal record. It is not a grade, not a license to carry your goods, and not proof of anything beyond registration.

What the number identifies

FMCSA requires companies that operate commercial vehicles transporting passengers or hauling cargo in interstate commerce to register and hold a USDOT number. The agency describes the number as the unique identifier under which a company’s safety information is collected: audits, compliance reviews, crash investigations and roadside inspections are all filed against it.

The registration thresholds are about vehicles and geography, not about moving in particular: a vehicle rated at 10,001 pounds or more, or one built or used to carry more than eight passengers for pay, used in trade or transportation that crosses a state line or passes through another state. Some states also require the number for carriers that never leave the state, so a USDOT number on its own does not tell you a company hauls interstate.

Where it must appear

Every advertisement for interstate household-goods services must carry the mover’s name or trade name exactly as it appears on FMCSA’s document assigning the number, and the number itself in the form “U.S. DOT No.” followed by the digits (49 CFR 375.207). A broker’s advertisements and website must show its USDOT and MC numbers as well (49 CFR 371.107).

The bill of lading issued before the mover takes your goods must show the mover’s registered legal or trade name with its physical address and, when known, the names and USDOT numbers of every motor carrier that will take part in the move (49 CFR 375.505). If a different number appears there than on the estimate, another company is doing the hauling.

What it is not

It is not operating authority. A company that carries other people’s goods for pay across state lines, or arranges that transport, also needs operating authority from FMCSA, identified by an MC, FF or MX docket number; a company may hold several authorities, and the type decides what it may carry (FMCSA, Get Operating Authority). A USDOT number with no household-goods authority is a registered company, not an authorized mover.

It is not a safety rating, an insurance certificate or a review score. Several unrelated companies can share a trade name, but only one holds a given USDOT number, which is why the number, not the name, is what you match.

How to use it

Take the number from the written estimate rather than from an advertisement or a website, enter it in Mover Check, and confirm that the legal name, the city and the household-goods authority on the record match the company you are dealing with. If the estimate has no number, ask for it in writing before anything else; a mover that advertises interstate service is required to publish one.
