How the MCS-150 schedule works
Every motor carrier with a USDOT number must update its registration, the MCS-150 form, every 24 months. The federal rule (49 CFR 390.19(b)) spreads the deadlines across the calendar using two digits of the number:
| Digit | What it decides | Rule |
|---|---|---|
| Last digit | Month | 1 = January, 2 = February ... 9 = September, 0 = October |
| Next-to-last digit | Year | Odd digit: odd-numbered years. Even digit (including 0): even-numbered years. |
The update is due by the last day of that month. If this year's deadline has already passed, the calculator moves to the next matching year.
Example: a number ending in 47 has a last digit of 7 (July) and a next-to-last digit of 4 (even), so it files by July 31 of every even-numbered year.
Why insurance agents use it
An MCS-150 deadline is a natural reason to call a carrier: it is a compliance task every carrier has, and the fleet size, driver count and mileage it reports shape the insurance conversation. Read more in MCS-150 biennial updates and why they matter to agents.
Questions
How is the MCS-150 due date worked out?
Under 49 CFR 390.19(b), the last digit of the USDOT number sets the month (1 is January through 9 is September, and 0 is October) and the next-to-last digit sets the year: odd digits file in odd-numbered years, even digits in even-numbered years. The update is due by the last day of that month, every 24 months.
Do I still have to file if nothing changed?
Yes. The biennial update is required even when every detail is the same. Filing confirms the record is current.
What happens if a carrier misses the MCS-150 update?
The regulation provides for civil penalties and deactivation of the USDOT number. A carrier with a deactivated number should not operate until the record is updated.
Can I file early?
A carrier can update its registration whenever its details change. This calculator shows only the scheduled biennial deadline; it does not know when a carrier last filed.
Is this an official FMCSA tool?
No. It applies the published schedule to the number you enter. Trucking Leads is not affiliated with FMCSA. Confirm a carrier's status on FMCSA's own systems.
