MCS-150 biennial update due date calculator

Every motor carrier must update its MCS-150 with the FMCSA every two years, even if nothing changed. Enter your USDOT number to see your due date.

How the schedule works

The FMCSA sets your filing month and year from the digits of your USDOT number (49 CFR 390.19T):

Last digitFiling month
1January
2February
3March
4April
5May
6June
7July
8August
9September
0October

The next-to-last digit sets the year. Odd digit, file in odd-numbered years. Even digit (including 0), file in even-numbered years. The update is due by the last day of your filing month.

What happens if you miss it

The FMCSA can deactivate your USDOT number, which stops you from operating until it is reinstated, and civil penalties can run up to $1,000 per day, capped at $10,000. Brokers and shippers also check your record, and an inactive number costs you loads.

How to file

File online through the FMCSA Registration portal at fmcsa.dot.gov/registration. You need your USDOT PIN. The update takes about ten minutes. Filing is free; you do not need to pay a third-party service to do it.

Got a letter or email demanding a fee? Companies send official-looking notices charging $95 to $300 to file this, often quoting fines of $1,000 a day. FMCSA does not send those. If you are unsure whether a notice is real, call FMCSA using the number on fmcsa.dot.gov, not the number in the letter.

Never miss the next one

We don't file it for you. We make sure you never miss it. The DOT Binder tracks your MCS-150, UCR, insurance, medical cards, annual inspections, and driver qualification files, and emails you before anything is due. 14-day free trial, no card.
