How this service works
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.
Output
Returns the carrier's current FMCSA profile including operating status (Active, Inactive, or Pending), safety rating tier, operating authority status, insurance flags, fleet size, and registered legal name and DBA name. If the USDOT number does not resolve to any known carrier, the call is free and an error or empty result is returned.
Example use cases
Pre-load carrier vetting
“Before we tender this load to Swift Freight LLC, can you look up USDOT number 1234567 and confirm they have active authority, no insurance issues, and a satisfactory safety rating?”
Carrier identity theft detection
“A carrier claiming to be 'Blue Ridge Hauling' gave us USDOT number 9876543 — can you check their FMCSA profile and verify the name on file actually matches 'Blue Ridge Hauling' and that their address is 482 Industrial Pkwy, Atlanta, GA 30301?”
Inactive carrier status check
“We have an old preferred carrier with USDOT 4567890 that we haven't used in a year — can you check if they're still active and see if anything has changed with their safety rating or insurance?”
Technical details
Endpoint
POSThttps://fmcsa-mcp-843680657471.us-central1.run.app/x402/lookup_carrier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already have a carrier's USDOT number and need their current regulatory profile. Prefer it over search_carriers when you have a specific USDOT to resolve, and over check_carrier_identity when you need the full profile rather than a targeted identity-verification check. Ideal for pre-load vetting, onboarding due diligence, and periodic compliance monitoring of known carriers.
Side effects
- Unknown USDOT number returns no carrier record (no charge applies)
- Network or service timeout if FMCSA upstream is slow
- Stale data if FMCSA records have not been recently refreshed
- Payment failure if USDC balance is insufficient for the $0.01 charge
- Invalid input type if usdot_number is not provided as an integer
