DOT — U.S. Department of Transportation
Parent: Cabinet department. Domains in this note: dot.gov, transportation.gov.
What they regulate
Cabinet-level transportation policy and oversight of operating administrations (including FAA, FMCSA, NHTSA, and others). Broker/authority checks usually land on the specific mode regulator: FMCSA for many motor property brokers, FAA for aviation certificates, FMC (independent) for ocean OTIs, STB for certain rail economic matters. A DOT.gov page is not itself an MC number or OTI license.
Always prefer the live .gov site over a third-party mirror. Index ≠ endorsement.
How to verify
- DOT home — Cabinet department for U.S. transportation policy and operating administrations.

Questions this page answers
Where do I verify a trucking property broker?
Start with FMCSA paths (and SAFER/company snapshot tools as applicable), not a generic DOT homepage alone.
Does DOT license ocean NVOCCs?
Ocean OTI/NVOCC licensing is primarily an FMC path. DOT is the cabinet department for transportation; FMC is a separate commission.
Is a BrokerMafia agency page an endorsement?
No. Index ≠ endorsement. BrokerMafia is not a government agency and does not issue licenses.
