What Is UCR Registration? Who Needs It, What It Costs, and How to Renew
Reviewed by the ICR Filings compliance team · Updated October 16, 2026
UCR stands for Unified Carrier Registration. It is a yearly registration, and a yearly fee, for companies that operate commercial vehicles in interstate commerce. The money goes to the participating states to fund motor carrier safety programs. It is run by the UCR Plan, a board of state, federal, and industry representatives, and it is separate from your USDOT number and your MC number.
Who has to register
- For-hire carriers that haul freight or passengers across state lines
- Private carriers that haul their own goods across state lines
- Brokers, freight forwarders, and leasing companies
For UCR, a commercial vehicle is a truck or bus with a weight rating of 10,001 lbs or more (counting the trailer it pulls), any vehicle hauling placarded hazmat, or a vehicle designed to carry more than 10 passengers, including the driver. Trailers are not counted on their own.
Interstate means the freight, not just the truck. A load that started in another state or country, or is headed to one, counts even if your truck never leaves your state. If every load starts and ends in your state, UCR generally does not apply.
How much it costs
The fee depends only on how many commercial vehicles you operate, not on how many states you run in. The 2027 fees range from $55 for 0 to 2 vehicles to $54,165 for more than 1,000. Brokers, freight forwarders, and leasing companies that do not operate trucks pay the lowest bracket. See the full 2027 UCR fee table, or look up your USDOT number to see your bracket.
UCR renewal: every year, before January 1
UCR does not renew itself. Each registration year runs January 1 to December 31, and registration for the next year opens on October 1. You register again every year, and the deadline is before January 1. The 2027 year is open now.
If your fleet grows or shrinks during the year, you do not file anything extra. The change shows up the next time you register.
How to register
- Have your USDOT number and an accurate count of the commercial vehicles you run interstate.
- Register and pay at ucr.gov, the UCR Plan's official site, or have a registration service do it for you.
- Keep the receipt. You do not have to carry proof in the truck, but you can.
While FMCSA's MCS-150 updates are paused during the Motus transition, the UCR Plan asks carriers to declare every commercial vehicle they run in interstate commerce when they register, even if the MCS-150 on file shows a different number.
Your base state
You register through one base state, usually the state of your principal place of business, and that covers you in every participating state. 41 states take part. Florida, Arizona, New Jersey, and six other states, plus Washington, DC, do not, but carriers based there still register if they run interstate. See UCR for Florida carriers. Georgia, Texas, and Pennsylvania all participate, so carriers there register the same way as everyone else.
What happens if you skip it
Participating states check UCR at roadside inspections and weigh stations starting January 1. Fines vary by state, and some states will not issue or renew IRP plates or IFTA credentials without a current UCR.
UCR, USDOT, and MC: how they differ
| Filing | What it is | How often |
|---|---|---|
| USDOT number | Your company's ID with FMCSA | Once, then an MCS-150 update every two years |
| MC number | Permission to haul regulated freight for hire, or broker it | Once |
| UCR | A yearly registration and fee paid to the participating states | Every year |
