DOT Number (USDOT)
A USDOT Number is a unique 7-8 digit identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to commercial motor vehicles operating in interstate commerce. The number identifies the carrier in federal compliance records, displays on the side of the truck, and is searchable in the public SAFER (Safety and Fitness Electronic Records) database. Carriers must register a DOT number before hauling regulated freight across state lines.
Why it matters
The DOT number is the carrier's compliance fingerprint. A single number unlocks the carrier's safety scores, crash history, inspection record, insurance status, and authority status — everything a shipper needs to verify before handing over freight. If the truck that shows up has no DOT number, an inactive number, or a number that does not match the booked carrier's rate confirmation, the shipment is at risk for cargo theft, insurance coverage gaps, or fraudulent re-brokering.
When to use it
Verify the DOT number at three points: (1) at booking — does the assigned carrier's DOT match the quoted carrier; (2) at pickup — does the truck's DOT match the rate confirmation; (3) on the BOL — is the carrying carrier's DOT the same as the booked carrier's. Mismatches signal double-brokering or carrier swap, both common cargo theft setups.
How Warp thinks about it
Every carrier on a Warp shipment has a verified DOT number, active insurance, current authority, and a clean safety score before they touch freight. The DOT shows on the Warp driver app at pickup. Carrier vetting is structural — re-brokering is impossible because the carrier-of-record cannot change once Warp dispatches the load.
