DOTWhat it is
The USDOT number is the identifier the U.S. Department of Transportation assigns to every company that operates commercial vehicles. It serves as your company’s registration number: it is displayed on the truck door and it is what a roadside inspector looks up.
It is issued by FMCSA and linked to your safety record, inspections and audits. It is therefore not a one-time formality: it must be kept current whenever your company information, fleet or operation changes.
What our service includes
- Review of your operation: interstate or intrastate, property or passengers
- USDOT number application with FMCSA
- Mandatory biennial update (Form MCS-150)
- Updates when your company, fleet or operation changes
- Reactivation of deactivated USDOT numbers
- Correction of errors in your registration
- Confirmation of your active number for vehicle marking
You need it if
- You operate a vehicle of 10,001 lbs or more gross weight
- You haul freight across state lines
- You transport hazardous materials in quantities that require placards

Frequently asked questions
Does the DOT number expire?
It does not expire, but it must be updated every two years with Form MCS-150 and whenever your company information changes. If it is not updated, the number is deactivated.
Is a DOT number the same as MC authority?
No. The DOT number identifies your company; MC authority permits it to haul third-party freight across state lines. Many carriers need both.
Do I need a DOT number if I only operate within Florida?
Florida requires a DOT number for commercial vehicles above a certain weight, even if they never cross state lines. We review the requirement against your equipment.
Can I file it myself?
Yes. Many clients entrust the filing to us because a single incorrect entry can block activation, and correcting it later takes longer than filing it correctly the first time.
