MCS-150 Biennial Update Checker

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

FMCSA filing schedule

Enter a USDOT number to calculate its scheduled MCS-150 update month and odd/even filing year. Add the last MCS-150 date from Company Snapshot for a more useful timing check.

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.
