}Use this when you need to know whether a US motor carrier's biennial MCS-150 update is due or overdue. For 1 to 10 USDOT numbers: next and last filing deadline (49 CFR 390.19T), days left in the carrier's state time zone, overdue flag, USDOT status, and deactivation enforcement: the FMCSA suspended it for updates due since 2026-06-01 and is unclear on earlier ones (notice, quote and read date returned). No personal data. Not a consumer report under the FCRA. Price: 0.005 USDC per call (x402).
