Steps

  1. Get a FMCSA Developer WebKey through Login.gov as described in the QCMobile Quick Start Guide.
  2. Strip any 'MC-' prefix from the mover's motor carrier number, leaving only the numeric docket number.
  3. Call GET https://mobile.fmcsa.dot.gov/qc/services/carriers/docket-number/{docketNumber}?webKey=YOUR_WEB_KEY.
  4. Read the returned carrier record's USDOT number and legal name to confirm they match what the mover advertises.
  5. If no record is returned, verify the docket number format (numeric only, no letters) before concluding the authority doesn't exist.
