How to Get a DOT Number

A USDOT number is how the federal government identifies and tracks your trucking operation. If you run a commercial vehicle over a certain weight, carry enough passengers, or haul interstate, you need one before you operate. Figuring out how to get a DOT number on your own means navigating the MOTUS Portal, the right operation classifications, and the MOTUS system. Tech Rig does it for you and gets it right the first time.

What a USDOT number is and who needs one

A USDOT number is your unique federal ID as a motor carrier. FMCSA uses it for safety records, inspections, audits, and crash data. You generally need one if you operate a vehicle that meets the federal weight, passenger, or hazardous-materials thresholds in interstate commerce, and many states require it for intrastate operation too. A USDOT number is not the same as operating authority (your MC number). Some carriers need only a USDOT number; others need both. We tell you which applies to your operation.

USDOT number
Identification and safety. Your federal ID for records, inspections, and audits.
MC number
Authority to haul for hire. The operating authority that lets you run loads for pay.

How to get a DOT number, step by step

  1. Decide your operation type and classification (carrier, interstate or intrastate, cargo type). Getting this wrong causes problems later.
  2. Set up your MOTUS Portal account.
  3. Complete the MCS-150 application, which creates your USDOT record.
  4. Submit and receive your USDOT number.
  5. If you also need operating authority, file your MC application and BOC-3 next.

This is doable yourself. It is also where new carriers most often stall, because of classification mistakes and MOTUS account issues.

What a USDOT number costs

$300USDOT registration, one time

Tech Rig service fee: $300, one-time, to register your USDOT number and set up your MOTUS Portal correctly. That $300 is the total for a standalone USDOT registration: there is no separate federal USDOT application fee. This price is for carriers who need a USDOT number only. If you also need operating authority, your MC filing includes the USDOT, so you would not pay this separately.

Need authority too? See the MC authority page, or get the full setup as one package.

Let us handle how to get a DOT number for you

A Texas owner-operator starting a single-truck dry van company came to us before he had any federal record. We opened his MOTUS Portal account, classified him as an interstate for-hire carrier with one power unit and one driver, and filed the MCS-150 with his cargo and operation details. His USDOT number issued on that registration. The piece new carriers most often get wrong is the operation classification, and a wrong answer there follows you into every later filing, so we set it correctly the first time.

What you get with us:

  • Correct operation classification from the start.
  • Your MOTUS Portal account set up properly.
  • Your USDOT number registered and confirmed.
  • A clean handoff into MC authority, BOC-3, and the rest if you need them.

USDOT number FAQ

Do I need a USDOT number, an MC number, or both?

It depends on your operation. Interstate for-hire carriers usually need both. Some carriers need only a USDOT number. We confirm which applies to you.

How long does it take to get a USDOT number?

The registration itself is quick once the application is correct. Government processing and MOTUS issues can add time, so we do not promise a date, but we keep your side moving.

What is MOTUS and why does it matter?

MOTUS is FMCSA's newer system. Existing records sometimes have to be claimed or linked before you can register or update, and that is where carriers get stuck. We handle it.

Can you reactivate an old USDOT number?

Yes. Reactivation often starts with an MCS-150 and may involve a MOTUS linkage. We do this regularly.

Is the USDOT number a one-time thing?

The number is yours, but you must keep it current with MCS-150 updates, including the biennial update.
