What is a USDOT number?
Researched and written by Daniel Novak · Reviewed by Brittany Evans · Last reviewed August 2026
A USDOT number is the identifier the Federal Motor Carrier Safety Administration assigns to a company when it registers with the federal government. It is a file number, not a licence to move your furniture. The number is how the agency attaches inspections, crash reports, audits and filings to one legal entity, and how anyone can pull that entity's public record without asking the company for permission.
The useful part of this page is the fourth section. An active USDOT registration is easy to display and easy to misread, and the gap between what it proves and what a sales call implies it proves is where most of the trouble on an interstate move begins.
Who is required to have a USDOT number?
Registration is tied to what a company does, not to how large it is. A company that transports property for compensation across a state line is operating in interstate commerce and must be registered federally before it does so. That covers a two-truck local mover who takes one job across the state line as squarely as it covers a van line. Companies operating only inside one state may still need a USDOT number, because a number of states require federal registration for intrastate carriers as well, and those state rules differ from each other.
Brokers register too. A company that sells you a move and then hands the job to somebody else is registered as a broker, holds its own number, and is not the party that carries your goods.
What does an active registration actually prove?
Four things, and they are worth having:
- A specific legal entity exists in the federal record, with a legal name and a physical address on file.
- That entity has an open federal file and has kept up the filing duties attached to it, including the biennial update of its registration form.
- The public record for that entity is available: fleet size, driver count, cargo classes, inspection and crash history.
- The company can be found again later. A number does not change when a trading name does.
What does an active USDOT registration not prove?
This is the part worth quoting. An active USDOT number is not authority to move household goods. Registration and operating authority are two separate records, and a company can hold an active registration while its household goods authority is pending, revoked or never granted at all. The cargo classes shown on the registration are the registrant's own tick boxes, filed by the company. Household goods appearing there means the company said it carries household goods. It does not mean the agency granted it the authority to.
An active number also does not prove any of the following:
- That the company has a satisfactory safety rating. Most registrants have never been rated at all, and an unrated carrier is not a failed one.
- That insurance is currently on file at the level your move needs. Insurance filings sit in a separate public record from the registration.
- That the company owns trucks. A registrant may file zero power units, and a broker files none by nature.
- That the crew arriving is employed by the company you booked.
- That the company has no complaint history. Complaints live in a separate federal database.
How the number appears in the paperwork
The number should be the same one in three places: the estimate, the bill of lading and the public record. If a company gives you a number that resolves to a different legal name, that is not a clerical detail. Confirm the number resolves to the entity whose name is on the document you are being asked to sign, and confirm the household goods authority separately from the registration.
