About fleetfax · Carrier Lookup & Vetting
Vet a carrier before you book the load, and catch the red flags.
Look up any carrier by USDOT, MC, company name, email or phone: authority, insurance, safety and plain-English cautions from public FMCSA records.
The fleetfax.com carrier report, free in a Chrome side panel beside your load board or email. No more pasting numbers into SAFER in another tab.
HOW IT WORKS
1. Open the panel: click the fleetfax icon, press Ctrl+Shift+F (Control+Shift+F on Mac), or highlight a USDOT, MC or name on any page, right-click it and choose Search with fleetfax. It stays open as you switch tabs.
2. Type or paste a number, name, email or phone. Suggestions appear as you type.
3. Cautions show at the top. Click one to see the record behind it.
