Sample record for illustration. Names, identifiers, values and dates are illustrative; this is not a live lookup.
Sources publish with a delay. Review the linked records and their dates when making a decision.
How it works
From a number to the records.
Built first for freight brokers.
Source dates and coverage limits apply.
Review the evidence
Open the source links and check publication dates. Missing fields stay unknown.
Follow the connections
Review companies sharing public-record identifiers. Shared details are leads to review, not proof of ownership or wrongdoing.
The evidence comes with it
Read the record.
Know its limits.
Sources can lag or fail, and a blank result does not establish a clean record.
Insurance filings are not a coverage determination, and historical authority actions are not current status.
How we check carrier records ↗What a fact includes
More than a value
- Published value
- The field returned by the source
- Source record
- A link to the public evidence
- Publication date
- When the dataset was updated
- Record date
- Shown when available
Watchlist
Watch the carriers you already use
- Checked nightly against the latest federal records. Publication delays and gaps may exist.
- A “what changed” view per carrier — new value next to old, with the source. Retained raw rows need review; blanks do not establish removals.
- Quiet by default — no alert noise. Review published records in your account.

Developers
API-first, MCP included
REST API + webhooks
Look up by USDOT through the REST API. Outbound watchlist webhooks are not available; review changes through the API or account.
MCP server
Use the vet_carrier tool for the core profile and evidence. History and relationships load through separate calls.
Sandbox with sample carriers
Try the synthetic sandbox without a test key. Live evaluation uses your account API key and monthly allowance.

Before you book
A few useful answers.
Why might a carrier or relationship be missing?
A USDOT number may be absent from the published census data, or a source may be delayed or unavailable. Missing data is not a verdict about the carrier.
Does a shared identifier prove a relationship?
Phones can be reassigned, addresses can be shared offices or homes, and officers can share names. A match does not prove that two carriers operated together or that their connection is current.
How do I dispute a fact?
Use the correction form. Reports await human review and never automatically change source facts.
Who uses it
Built first for freight brokers.
The same evidence record can help factoring companies check a carrier before buying its invoices, shippers vet carriers they hire directly, and insurance agents verify a carrier’s filings. Source dates and coverage limits apply.
