Quick answer

If your USDOT number ends in 0, your biennial update is due in October. Which October depends on the digit before the last one. Odd means odd-numbered years. Even means even-numbered years. You get the whole month, and FMCSA will take it up to 90 days early.

Odd (1,3,5,7,9)October 2027 October 2029October 2031
Even (0,2,4,6,8)October 2026 October 2028October 2030

USDOT 123430 ends 3 then 0. The 0 means October. The 3 is odd, so odd years. Due October 2027.

USDOT 123460 ends 6 then 0. The 0 means October. The 6 is even, so even years. Due October 2026.

Why October

FMCSA spreads the work across the year so every carrier is not filing at once. The rule is in 49 CFR 390.19: the last digit of your USDOT number sets the month, and the digit before it sets whether you file in odd or even years.

Source: the biennial update requirement and schedule sit in 49 CFR 390.19. FMCSA states the update is required every 24 months whether or not your details have changed.

This is why asking another driver when his is due tells you nothing. His number ends in a different digit.

If you miss October

The penalty is up to $1,000 for every day it is late, to a maximum of $10,000. Then FMCSA can switch your USDOT number off.

A switched-off number is not a fine you settle later. The officer stops the truck at the next inspection, with your load on it, and you cannot legally run interstate until the record is put right.

We will tell you your exact date.

Put in your USDOT number. We read your official FMCSA record and show you the date, plus everything else you owe. Free, and you do not need an account.

$109 and we file it. Money back if it is rejected.
