MC Certificate Documents (2 letters, 2 PDFs)
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.
