One Thing FMCSA Can't Tell You

FMCSA confirms this carrier's authority exists. It can't confirm the person dispatching is who records say — that's how double brokering and cargo theft happen.

  • The Supreme Court's vicarious liability ruling means one unvetted carrier can expose you to a nuclear verdict.
  • Double brokering is at record highs. Scammers clone legitimate authority and re-broker your load.
  • Purple Squirrel closes the gap: MVR pulls + selfie ID checks prove the driver is who records say.

Get Notified If Anything Changes — Free

We'll email you if this carrier changes status

We check FMCSA weekly and alert you if authority status or official safety rating changes — revocations, suspensions, or rating updates.

FMCSA only updates the official safety rating after a formal audit — most carriers never get one. New inspections and crashes won't trigger this alert. For real-time protection against scams and liability — proof that the driver picking up your freight is actually who the records say — that's what our paid MVR + selfie ID verification does.

Did this company contact you by email?

Enter the email address they used. We'll check if the domain is legitimate, how old it is, and whether it matches what FMCSA has on file.

Mainstream software is leaving you high and dry. We verify the identity of the person representing the carrier and the safety of the driver behind the wheel.See How →
