FMCSA Carrier Check
Authority and insurance before you tender
Overview
Carrier vetting against FMCSA public data, built to say when it does not know
Before a load is tendered, somebody checks the carrier's authority and insurance. If that check quietly fails, a load has been dispatched to an operator who is not allowed to run.
Enter a USDOT or MC number and get operating authority, insurance filings, safety rating and twenty-four months of inspection and crash history from FMCSA's public data. Every check is shown against the named fields it reads, so the derivation is visible — there is no weighting and no proprietary score.
