Updating Your USDOT Number

USDOT numbers must be updated at minimum every two years to meet the Biennial update requirement, regardless of whether you conduct interstate or intrastate travel, even if you have not had changes to your operations.

If the second to last digit in your USDOT number is even your USDOT number needs to be updated in even numbered years. If the second to last digit in your USDOT number is an odd number your USDOT number needs to updated on odd numbered years.

The last number in your USDOT number calls out the month in which your USDOT number should be updated.

• 1= Update due in January

• 2= Update due in February

• 3= Update due in March

• 4= Update due in April

• 5= Update due in May

• 6= Update due in June

• 7= Update due in July

• 8= Update due in August

• 9= Update due in September

• 0= Update due in October

In addition to the Biennial Update requirement your USDOT number should be updated any time the following occur;

• Change in the number of CDL drivers in your fleet

• Change in the number of NON CDL drivers in your fleet

• You begin interstate operations and were previously an intrastate carrier
