Use this when you already have a carrier's USDOT number and need its current pro
Use this when you already have a carrier's USDOT number and need its current profile: safety rating, authority status, insurance flags, fleet size. Returns Active, Inactive, and Pending carriers alike. Billed only when the number resolves to a real carrier; an unknown number is free.
