Your biennial update isn’t about when you got your USDOT number; it’s needed every two years, depending on the last two digits of your number. This means you might have to file the update a few months after getting your USDOT number.
Every two years, a carrier must provide this update, even if the company’s information hasn’t changed, it has stopped Interstate operations, or is no longer in business, and you didn’t inform the FMCSA.
Changes or updates that happen outside your required biennial update month and year, like adding or removing drivers or vehicles, are categorized as an “Edit.” Ensure you file an edit within 30 days of the change.
If the next-to-last digit of your USDOT number is odd, you file in odd-numbered years. If it is even, you file in even-numbered years. The last digit tells you the month it is due.
