FMCSA cargo filing (BMC-34/83)

No active FMCSA cargo filing on file.

FMCSA L&I filing evidence — not a shipper certificate of insurance (COI). Cargo (BMC-34) is primarily an HHG / household-goods requirement; general freight carriers often have none.

Broker bond / trust (BMC-84/85)

No active broker surety bond or trust fund on file.

BMC-84 is a surety bond; BMC-85 is a trust-fund agreement. Required for property brokers / freight forwarders — not motor-carrier BIPD liability insurance.

Authority Records (above) are FMCSA docket status and lifecycle events. MC Certificate Documents here are the archived PDF letters for each action — grants, reinstatements, revocations, name changes, and transfers. They are related but not the same dataset: one row per PDF letter, not one file per docket.

Each row is a distinct FMCSA letter (grant, reinstatement, revocation, name change, transfer, etc.). When a PDF is archived, click the link to open that letter. Rows without a link still show the action type and date from our index. FMCSA stopped publishing new daily certificate PDFs after the May 2026 Motus cutover — rows below are historical archive only.
