How the Unified Carrier Registration program works
Most carriers know UCR as a yearly bill. Knowing who sets it, where the money goes, and which websites are official makes the fee easier to plan for and harder to overpay.
The UCR program in numbers
The Unified Carrier Registration program is a federal law under which interstate motor carriers, brokers, freight forwarders, and leasing companies pay one yearly fee through ucr.gov. A 15-member board recommends the fees, FMCSA sets them by rule, and the money funds motor carrier safety work in the 41 participating states.
UCR usually reaches a carrier as a bill or a phone call: pay this before January 1. Fewer people know why the fee exists, why it fell for a few years and is rising again, or who ends up with the money.
This guide explains the program behind the fee: the law, the board, how the fee is set and spent, and how to tell the official UCR websites from look-alikes. For the deadline and filing steps, see our UCR renewal guide.

Key takeaways
Federal law, state money
Congress created UCR in 2005. You pay through a base state, and 41 participating states share the revenue.
A board recommends, FMCSA decides
The 15-member UCR Board recommends the fees, and FMCSA sets them by rule after public comment.
The revenue target is fixed
Fees rise when collections fall short of what the states are owed, and must fall when there is a surplus.
The money must fund safety
Each participating state must spend at least its UCR revenue on motor carrier safety, enforcement, or running UCR.
Only ucr.gov takes registrations
Services may file for you, but the UCR Plan doesn't regulate their fees, and impostors have posed as the program.

What is the Unified Carrier Registration program?
It is a state revenue program created by federal law. The UCR Act of 2005, part of the SAFETEA-LU highway bill, added 49 U.S.C. 14504a, which replaced the old Single State Registration System with one yearly registration and fee.
In return, states gave up separate charges. A state may not make an interstate carrier register its interstate operations with it, file its federal insurance or process agent with it, or pay a fee that intrastate-only carriers don't pay.
Two names describe the program. The UCR Plan is the organization of state, federal, and industry representatives that runs it. The UCR Agreement is the interstate agreement that governs how fees and registration information are collected and shared. UCR is also separate from your USDOT registration; our guide to UCR vs USDOT, MC, IRP and IFTA shows where the two connect.
Who is outside the program
Interstate motor carriers of property (for-hire, private, and exempt), for-hire passenger carriers, brokers, freight forwarders, and leasing companies are subject, wherever they are based. Our renewal guide covers that list and what to do if your state doesn't participate. The program's edges come from the Act and the UCR Handbook:
- Outside UCR: carriers that operate only intrastate, private carriers of passengers, carriers operating solely within Hawaii (except household goods movers for individual shippers), and governments, from towns and counties to tribes and federal agencies, running their own vehicles.
- Still subject: businesses hauling under a government contract, such as U.S. Postal Service mail carriers; truck-driving schools that aren't government-run; and private carriers hauling their own property across state lines.
- Light vehicles only: a business with an MC number but no commercial motor vehicles still registers, normally in the lowest bracket. Once a pickup and trailer reach 10,001 pounds combined in interstate use, that unit counts.
The UCR Plan's Do I Need to Register? questionnaire walks through each case.
Who runs the UCR program?
A 15-member board of directors runs UCR, not FMCSA and not the states. The Secretary of Transportation appoints the directors, and the law fixes the mix:
- Four chief administrative officers of state UCR agencies, one from each of FMCSA's four service areas
- Five professional staff members of state UCR agencies, nominated through their national association
- Five motor carrier industry representatives, including at least one from a national trade association of property carriers and one carrier from the smallest fee bracket
- FMCSA's Deputy Administrator, or another presidential appointee from the Department of Transportation
Directors serve three-year terms. The board writes the rules of the UCR Agreement, designates the depository that holds the money, and recommends the fees. It may hire contractors for administrative work, but it can't hand off decisions or policy.
Participating states collect and enforce the fee, but as participants they have no role in governing UCR; that authority sits with the board. FMCSA sets the fees by rule and holds one board seat. It doesn't collect UCR fees, and the money doesn't go into its budget.
The board meets in public
Board and subcommittee meetings are open to the public, announced in the Federal Register, and usually held by conference call and Zoom. The UCR Plan posts agendas, minutes, and board decisions on plan.ucr.gov, along with requests for nominations when an industry seat opens.
How are UCR fees set?
The UCR Board recommends a fee schedule, and FMCSA adopts it by rule within 90 days, after notice and public comment. The law requires four to six brackets based on fleet size, fees that rise with each bracket, and the smallest fee for every broker and leasing company.
The fees aim at a fixed revenue target, not a budget that grows. Each participating state is entitled to a set amount a year, based mainly on what it collected under the old system, and those entitlements total somewhat more than $107 million. With the program's administrative costs added, FMCSA put the total the 2027 fees must raise at $118 million.
When collections fall short of the target, fees go up. When they exceed it, the surplus stays in the depository and FMCSA must cut the next fees. That is why the fee has moved in both directions:
| Registration year | 0–2 vehicles, brokers, leasing | 6–20 vehicles |
|---|---|---|
| 2019 | $62 | $368 |
| 2020–2022 | $59 | $351 |
| 2023 | $41 | $242 |
| 2024 | $37 | $221 |
| 2025–2026 | $46 | $276 |
| 2027 onward | $55 | $333 |
The 2023 and 2024 cuts, which averaged 37.3 percent over the two years, returned earlier over-collections and left a gap. FMCSA raised 2025 fees about 25 percent to cover a $13 million shortfall, then 2027 fees an average of 20 percent to cover a projected $21.79 million shortfall, noting that past excess collections are now used up.
The 2027 schedule stays in place until a future rule changes it. Collections for a fee year run from October 1 before the year to December 31 after it, so the board always recommends fees before the last year's money is fully counted. To place your own fleet in a bracket, see our guide to calculating your UCR fleet size.
Where does your UCR fee go?
Your fee goes to the participating states and to the cost of running the program. You pay through your base state, and the money moves in this order:
- Your base state keeps its share first. It retains what it collects up to its yearly entitlement and sends the rest to the UCR depository, which the board holds at the Bank of North Dakota.
- The depository tops up the other states. Generally each month, it pays states that haven't reached their entitlement, pro rata.
- Then it pays the program's costs. Congress has never authorized appropriations for UCR, so fees cover the registration platform and other expenses, including a $250,000 allocation for legal defense in the 2027 fee calculation.
- Anything left lowers future fees. The law requires FMCSA to reduce the next fees by the surplus.
Where you're based doesn't change what you pay. The fee depends only on your fleet size, so a carrier that runs only in nonparticipating states pays the same as one with the same fleet running in all 41 participating states. Nonparticipating states receive nothing.
To join, each participating state had to file a plan showing it will spend at least as much as its UCR revenue on motor carrier safety programs, enforcement, or administering UCR. In March 2026 the board voted to ask every participating state to document that spending.
Which UCR websites are official?
Two websites belong to the program. ucr.gov is the National Registration System, where you register, pay, enroll in auto-renew, and check any company's status. plan.ucr.gov is the UCR Plan's site, with the fee brackets, handbook, FAQs, participating states, and board documents.
With 2027 registration open, ucr.gov asks carriers to declare every commercial motor vehicle they operate in interstate commerce when they register, because FMCSA has suspended required biennial MCS-150 updates. Our MCS-150 biennial update guide covers that pause.
Filing services and impostors
You may pay a third party to register for you. The UCR Plan doesn't regulate what such services charge, though some states have their own rules. That applies to us too: whoever files for you, ask for the National Registration System receipt so you can compare the UCR fee with the official bracket.
Impostors are a different problem. In 2016 the FTC charged the operators of a scheme that used official-sounding names, warnings of $1,000 fines, and threats of law enforcement to sell UCR and other registrations. The FTC alleged they took more than $19 million from small trucking businesses, with service fees of $25 to $550 or more folded into the total.
In January 2026, FMCSA warned of phishing emails posing as USDOT and FMCSA, and said it will never request payment or sensitive information, such as UCR details, through unsolicited messages. Before you pay anyone:
- Type ucr.gov into your browser instead of following a link in an email, text, or ad.
- Check the free UCR registration lookup to see whether the year is already paid.
- Compare the amount with the official fee for your bracket. Anything above it is a service fee.
- Ignore demands to buy a UCR decal or card. There is no UCR credential, and no state may require one in the truck.
How Simplex helps with UCR
We file UCR each year and keep the USDOT record behind your bracket current, so the fee you pay is the one you owe.
UCR filed every year
Our UCR registration and renewal service files or renews your UCR so the fee for your bracket is paid in full and on time.
A USDOT record that matches
With MCS-150 updates paused, the count UCR reads can be stale. Our trucking authority packages cover USDOT and MC applications, BOC-3, and MCS-150 setup and updates.
The rest of your permits
Our permits team handles IRP trip permits, temporary fuel permits, and oversize and overweight permits alongside UCR.

Pay UCR once, at the right fee, in the right place
UCR is a fixed-target fee: it rises when collections fall short and falls when there is a surplus. Knowing that, and knowing that only ucr.gov takes registrations, makes the yearly bill easier to budget for and harder to overpay.
