How to look up a DOT number
- Find the number. It is painted on the cab door, or printed on your MCS-150 and any rate confirmation. It is a USDOT number, sometimes paired with an MC (operating authority) number.
- Enter it in the tool above and run the lookup. Numbers only, four to eight digits.
- Read the snapshot: whether the authority is active, the FMCSA safety rating, fleet size, insurance on file, and operating radius.

What your DOT lookup shows
- Operating authority – active, inactive, or none. Authority that flickers between active and revoked is almost always an insurance-payment problem.
- Safety rating – Satisfactory, Conditional, Unsatisfactory, or, for most small carriers, not rated (which is normal).
- Fleet size – power units and drivers, straight from the carrier's MCS-150 filing.
- Insurance on file – whether the federal liability filing (BMC-91X) is active, and any pending cancellation. Here is what those filings actually are.
- Operating radius – local, regional, or long-haul, one of the biggest factors in an insurance quote.
Why run a DOT number lookup?
Everyone in the chain uses it. Carriers should check their own number monthly, because it is exactly what brokers and insurance underwriters see. Brokers and shippers vet carriers before tendering freight. Owner-operators buying a truck can check how hard the seller ran the operation. It is free, public, and takes about thirty seconds.
And because your safety data is what underwriters price from, your DOT snapshot is the first thing we pull before we quote. Run yours, then start a quote and it pre-fills the application.
DOT lookup FAQ
Is the DOT lookup free?
Yes. It pulls public FMCSA records in real time, with no account or sign-up required.
What is a USDOT number?
It is the federal ID for a motor carrier, the number FMCSA uses to track a company's safety record, inspections, and filings. It is painted on every commercial truck's door. An MC number is different: that is the operating authority to haul for-hire freight.
How do I find my DOT number?
Check the driver-side cab door, your MCS-150 registration, or any rate confirmation. If you still cannot find it, search by company name in FMCSA's system, or start a quote and we will pull your file for you.
What is the difference between a DOT number and an MC number?
The USDOT number identifies and tracks the carrier. The MC number is the operating authority, the legal permission to haul regulated for-hire freight across state lines. A carrier can hold a DOT number before it is ever granted authority.
Can I look up any carrier's DOT number?
Yes. FMCSA records are public, so you can run any carrier you are vetting, whether you are a broker checking a carrier or a driver checking a company before leasing on.
