MCS-150 Biennial Update Checker

Calculate the FMCSA biennial update schedule associated with your USDOT number.

FMCSA filing schedule

Type your company name or USDOT number. We read the last MCS-150 filing on record in the FMCSA motor carrier census and show your scheduled deadline, the filing window and any overdue risk.

How the MCS-150 schedule is set

Last USDOT digit

Sets the filing month: 1 is January through 9 is September, and 0 is October.

Next-to-last digit

Sets the filing year: an odd digit means odd-numbered years; an even digit means even-numbered years.

Update window

FMCSA says an update completed during the 12 months immediately before the due date satisfies that biennial update.

Official sources

Rules and agency systems can change. Check the linked source before making a filing or compliance decision.
