The UCR program started after the UCR Act of 2005. It replaced the old system called SSRS to make things easier. Instead of registering in each state, carriers now register once and follow the same rules across all participating states. This helps cut down on paperwork and makes enforcement more consistent.
It’s not just some optional form, it's the law. And this law is mandatory for any motor carrier, broker, or freight forwarder who operates across state lines. In simple terms, if your truck crosses into another state,even just once for business, you’re engaged in interstate commerce and must have a valid UCR registration.
What Is a UCR Registration?
UCR stands for Unified Carrier Registration, and no, it’s not a license plate, and you won’t get any stickers in the mail. It’s a fee-based federal system that applies to anyone involved in interstate commerce, including carriers, brokers, freight forwarders, and leasing companies.
UCR is based on fleet size, which means the more commercial vehicles you operate across state lines, the higher your annual fee. For example, in Ohio, a single-truck operation may pay around $41, while a carrier with over 1,000 vehicles could pay over $39,000. UCR must be renewed annually, with registration for the upcoming year typically opening each October and due by December 31 to avoid penalties.
Is UCR the Same as an Apportioned Plate?
Absolutely not! But this confusion is common among truckers. Here is how to differ them:
- UCR registration does not come with a physical license plate or sticker. It’s a flat annual fee based on the number of commercial vehicles in your fleet and is required for interstate carriers, brokers, and leasing companies, even if they don’t operate trucks themselves.
- On the other hand, an IRP apportioned plate is an actual license plate issued for vehicles that travel in two or more states or jurisdictions. The fees are based on how many miles your vehicle travels in each state, and it's required for most commercial vehicles with a gross weight of 26,000 pounds or more.
So in short: UCR = compliance fee, IRP = plated authorization.
Is UCR and IRP the Same Thing?
| Aspect | UCR (Unified Carrier Registration) | IRP (International Registration Plan) |
| Purpose | Registration for interstate travel | Compliance verification |
| Managed by | FBI (Federal Bureau of Investigation) | Typically managed by local or state law enforcement agencies |
| Fee Bases | Mileage + states traveled | Number of vehicles in fleet |
| Physical Evidence | License plate issued | None |
| Who Must Register | Vehicle owners | Carriers, brokers, leasing companies |
| Example System | Legacy UCR Summary Reporting System | NIBRS (National Incident-Based Reporting System), an evolution of IRP |
| Offense Categories | Limited categories (Part I and II crimes) | More comprehensive offense categories |
I Have to Renew My UCR Every Year?
Yes - you absolutely do!
The UCR registration must be renewed annually. The registration period typically opens on or around October 1st for the upcoming calendar year. For example, UCR for 2026 would open in October 2025.
Who Needs to Register?
You must register if your company operates commercial motor vehicles in interstate or international commerce, including:
- Motor carriers
- Freight forwarders
- Leasing companies
- Brokers (brokers pay the lowest fee tier)
What’s Required to Register?
To complete or renew your UCR, you'll need:
- DOT Number (USDOT Number)
- Legal Company Name
- Number of Commercial Motor Vehicles operated in interstate commerce (used to determine your fee bracket)
If you are a broker or leasing company that does not operate commercial vehicles, you still need to register but only pay the minimum fee.
How Are UCR Fees Calculated?
UCR fees are calculated based on the number of commercial motor vehicles (CMVs) you operate in interstate or international commerce, not by the state you're based in.
Key Factors That Affect UCR Fees
- Fleet Size - The main factor. UCR fees are based on how many qualifying CMVs you operate across state lines.
- Interstate Commerce Only - Only vehicles involved in interstate (or international) transport count toward your UCR fee bracket. Intrastate-only vehicles are excluded.
- Fee Brackets - There are six fee brackets, and the cost increases as your fleet size grows.
Brokers, freight forwarders, and leasing companies that don’t operate CMVs pay the lowest bracket fee.
Do States Set Their Own Fees?
No. While the United Carrier Registration Agreement is administered at the state level, the fees are standardized nationwide and set by the UCR Board, not by individual states. However, not all states participate in UCR enforcement, but if your business operates in any participating state, you're still required to register.
What Vehicles Fall Under UCR?
- Power units (not trailers)
- CMVs over 10,001 lbs. GVWR
- Vehicles carrying hazardous materials
- Passenger vehicles with more than 8 passengers (for hire) or more than 15 passengers (not for hire)
How to File for UCR Registration
Before starting the process, collect USDOT number, the company legal name and DBA, employer ID or SSN, number of commercial motor vehicles used in interstate commerce:
- Includes power units only (not trailers)
- Must be over 10,001 lbs. GVWR or meet passenger/HazMat criteria
After gathering the necessary documents, visit the Official UCR Website. Select ‘’register’’(if it’s a new business) or ‘’renew’’ (if you’ve registered before). Report the number of qualifying interstate commercial motor vehicles in your fleet (as of June 30 of the previous year). This determines your fee bracket. After it you choose the payment method and then print and save the confirmation and receipt. Some states may require UCR proof during roadside inspections.
Not filing your UCR can lead to serious consequences, including fines of up to $5,000 per vehicle, possible vehicle impoundment, delays during roadside inspections, suspension of authority, and even out-of-state orders issued during inspections.
