The short answer for Missouri
Missouri centralizes many carrier credentials through MoDOT Motor Carrier Services after entity formation.
If you haul federally regulated property for compensation in interstate commerce, the federal registration stack generally includes a USDOT number, operating authority, BOC-3 process-agent designation, accepted insurance filing, and UCR. State accounts are separate.
Interstate or intrastate?
Missouri may impose intrastate registration, permit, tax, or insurance rules in addition to federal requirements. Confirm the exact rule with Missouri Department of Transportation Motor Carrier Services before hauling only within Missouri.
Interstate commerce
A shipment can remain interstate commerce even when your truck stays inside Missouri. Look at the cargo's fixed and persistent intent, origin, and destination.
Pure intrastate commerce
State-only work can avoid federal MC authority while still requiring a state number, permit, insurance filing, tax account, or safety registration.
Missouri authority launch sequence
- Register the business with Secretary of State Business Services
- Obtain EIN and open a business bank account
- Price commercial insurance before submitting authority
- Complete USDOT and MC filings with matching entity data
- Personally complete Motus identity verification
- Arrange BOC-3 and accepted insurance filings
- Register UCR for the current year
- Apply through Missouri MoDOT IRP/IFTA when IRP or IFTA thresholds apply
- Confirm intrastate rules with Missouri Department of Transportation Motor Carrier Services
- Build driver, vehicle, maintenance, and safety files before the first load
Costs to budget
Federal authority
$300
Per authority type; USDOT registration itself is free.
Insurance
Quoted
Driver, vehicle, cargo, radius, and location control the price.
State credentials
Variable
Missouri registration, plates, permits, and taxes are separate.
Never treat an undated “all-in” number as a quote. Insurance and vehicle credentials usually create more variance than the federal filing fee.
