Interstate can describe the full shipment
A vehicle does not always need to cross a state line itself. Property or passengers may be part of a movement that crossed—or will cross—a state or national border before or after one in-state segment.

UCR Registration: Requirements, Fees, and the Official Portal
Understand who is generally subject to Unified Carrier Registration, estimate the published 2026 fee, and continue to the official government-supported filing system.
USDOTData does not collect UCR fees or submit registrations.
Use the official UCR Plan for eligibility and UCR.gov for registration. This page is informational, not legal advice.
What UCR registration covers
UCR is an annual base-state registration and fee program for many businesses involved in interstate or international transportation. Covered entities register once for the year and pay through one base state on behalf of participating states.
It is separate from obtaining a USDOT number, applying for operating authority, filing insurance or BOC-3 records, updating an MCS-150, registering vehicles, or meeting IRP, IFTA, cargo, route, and state-permit rules.
Who is generally subject to UCR?
The UCR Plan generally identifies these interstate or international entities: for-hire, private, and exempt motor carriers; freight forwarders; brokers; and leasing companies. Canadian and Mexican carriers operating in the United States can also be subject.
Intrastate-only operations need a separate check
A purely intrastate entity may not be subject to UCR, but state motor-carrier rules can still apply. Use the official questionnaire and state agency when the facts are uncertain.
Count vehicles with the UCR definition
For the UCR fee bracket, current official guidance describes a commercial motor vehicle as a self-propelled highway vehicle used in commerce that meets at least one condition:
- Gross vehicle weight rating or gross vehicle weight of at least 10,001 pounds.
- Gross combination weight rating or gross combination weight of at least 10,001 pounds with trailing equipment.
- Carries placarded quantities of hazardous materials, regardless of weight.
- Designed to carry more than 10 passengers, including the driver.
A business can still have a UCR obligation with zero vehicles in this definition. Certain entities with federal operating authority use the lowest fee bracket. Use the official instructions instead of treating zero qualifying vehicles as an automatic exemption.
Published 2026 UCR fee brackets
Fees change by registration year. These amounts reproduce the current 2026 UCR Plan schedule and should be rechecked immediately before payment.
| Vehicles | Carrier or vehicle-operating forwarder |
|---|---|
| 0–2 | $46 |
| 3–5 | $138 |
| 6–20 | $276 |
| 21–100 | $963 |
| 101–1,000 | $4,592 |
| 1,001 or more | $44,836 |
Brokers and leasing companies use the approved 2026 base fee of $46. Confirm freight-forwarder treatment and any service fee in the official system.
A safer UCR registration workflow
1. Confirm the exact entity
Match the legal name, USDOT number, principal place of business, entity type, and current fleet. Similar names can point to different records.
2. Check whether UCR applies
Use the official eligibility questionnaire. Answer for the full interstate or international movement, not one isolated trip.
3. Use the official portal
Start at UCR.gov and check the domain before entering business or payment information. Distinguish the official fee from optional service charges.
4. Select year and base state
UCR is annual. Choose 2026 for an unresolved 2026 obligation and follow the base-state hierarchy, including when the home state does not participate.
5. Verify the fee bracket
Review the commercial-motor-vehicle count and entity type. A stale MCS-150 power-unit count can lead to the wrong bracket.
6. Save and recheck
Keep the official confirmation and receipt, then verify that the correct entity and registration year appear in the official system.
Separate each carrier check
UCR registration is one record. Identity, USDOT status, authority, insurance, process-agent filings, MCS-150 timing, and safety information each answer a different question.
UCR registration questions
Who generally has to register for UCR?
The UCR Plan generally covers for-hire, private, and exempt motor carriers, freight forwarders, brokers, and leasing companies involved in interstate or international commerce. Official exceptions and fact-specific rules apply.
Is UCR registration the same as a USDOT number?
No. A USDOT number identifies a carrier in federal registration and safety data. UCR is a separate annual registration and fee obligation for covered entities.
How much is UCR registration for 2026?
Published 2026 fees range from $46 for the 0–2 vehicle bracket to $44,836 for 1,001 or more vehicles. Brokers and leasing companies use the $46 base bracket. Always verify the live official schedule before paying.
Where is the official UCR registration website?
The official National Registration System is at UCR.gov. The UCR Plan website at plan.ucr.gov provides the current eligibility questionnaire, fee schedule, participating-state contacts, and governing materials.
