What Is the Unified Carrier Registration Plan? Who Runs UCR and Where the Money Goes

Most carriers meet the words “Unified Carrier Registration Plan” on a receipt, a state DOT page, or a suspicious-looking envelope, and never learn what the Plan is or who is behind it. It is worth ten minutes, because knowing who actually runs UCR tells you where to file, who can change the fee, why the money goes where it goes, and which senders have no business asking you for it. The Plan’s own one-line definition: “the organization of State, Federal and industry representatives responsible for developing, implementing and administering the UCR Agreement.” This guide unpacks that sentence. If you are after the basics of the filing itself, start with what is UCR registration.

The Act, the Agreement, and the Plan

Three things share the name, and people swap them freely.

• The UCR Act is the law. Congress created UCR in the 2005 highway bill, SAFETEA-LU (Public Law 109-59, enacted August 10, 2005), replacing the old Single State Registration System, and codified it at 49 USC §14504a. It was amended in 2008 by Public Law 110-244 and Public Law 110-432. The fee table itself is a regulation, 49 CFR 367.50.
• The UCR Agreementis the interstate agreement the statute authorizes: the rules that govern how registration information and fees are collected from carriers and distributed among the participating states. When you see “UCR Agreement registration year,” this is the document being quoted.
• The UCR Planis the organization — the board and its administrative apparatus — that develops and administers the Agreement, runs the National Registration System, and publishes the UCR Handbook that state administrators and auditors work from.

“UCR” on its own is the program: the annual registration and fee that interstate motor carriers, motor private carriers, freight forwarders, brokers, and leasing companies owe under all three.

Who sits on the UCR board

Section 14504a(d) fixes the board at 15 directors, all appointed by the Secretary of Transportation:

• Fourchief administrative officers of the state agencies that run UCR — one from each of FMCSA’s four service areas;
• Five from the professional staffs of those state agencies, nominated by their national professional association;
• Five from the motor carrier industry, of whom at least one must come from a national trade association representing general motor carriers of property and at least one must represent a carrier in the smallest fleet bracket;
• One federal seat: the Deputy Administrator of FMCSA or another presidential appointee from the Department of Transportation.

Directors serve three-year terms after the initial staggered appointments. The statute requires standing industry advisory, audit, and dispute resolution subcommittees; the Plan’s FAQ lists seven working subcommittees — industry advisory, audit, revenue and fees, procedures, UCR systems, best practices, and depository. Board and subcommittee meetings are open to the public and noticed in the Federal Register. That mix is the point: the states that collect the money and the carriers that pay it both have votes, and a decision to exclude a class of carriers from UCR needs three-quarters of the board rather than a simple majority.

What the Plan actually does

The statute hands the board the job of writing the rules of the Agreement: uniform forms and formats for what carriers submit and what states transmit, the procedure for changing base states, how excess fees are paid over and distributed, dispute resolution with due process, and the designation of a depository. In practice that shows up as five things a carrier can see.

1. The National Registration System at ucr.gov, launched September 10, 2021 to replace the Indiana-hosted system, where every registration is filed and looked up by USDOT number. Which door to use is covered in where to file UCR.
2. The base-state rules— which state gets your registration, and which participating state a carrier from Florida, New Jersey, Oregon, or the other seven non-participating jurisdictions must choose. The mechanics are in the base state guide.
3. The annual fee recommendation, sent to the Secretary of Transportation and published on plan.ucr.gov once final.
4. Audit standards that participating states must follow, including the bracket-retreat and anti-fragmentation checks that keep the fee schedule honest.
5. Rules for third-party filers. The Plan runs a service-provider module inside the registration system and binds filers who use it to disclose that they are private, that they charge an additional fee, and that carriers may register directly at ucr.gov. FastUCR is one of those private third-party services, not a government agency, and files under exactly that disclosure.

The Plan’s help desk is 1-833-UCR-PLAN (1-833-827-7526) and helpdesk@ucr.gov. Mailed payments — a voucher generated at ucr.gov plus a check — go to Unified Carrier Registration Plan, PO Box 2935, Idaho Falls, ID 83403-2935, per Texas DMV’s UCR page; confirm the address on your voucher.

How the fees are set

The board does not simply pick numbers. Section 14504a(f) requires between four and six brackets by fleet size with a progressive fee scale, and requires brokers and leasing companies to pay the smallest bracket regardless of equipment. Section 14504a(d)(7) requires the board to recommend fee levels sized to a target: the sum of every participating state’s revenue entitlement plus the Plan’s administrative costs, divided across the expected number of registrants by bracket. The Secretary of Transportation then sets the fees within 90 days of the recommendation, after notice and public comment, and FMCSA publishes them in 49 CFR 367.50. That is why a fee change is a rulemaking, and why you can read the Plan’s recommendation in the Federal Register months before it takes effect.

For 2026 the schedule the Plan publishes is:

These are unchanged from 2025. For 2027the board’s recommendation was a proposed increase, not yet final at this writing — the UCR 2027 guide tracks where that stands. Whatever the final numbers, they apply to the whole registration year no matter when you file.

Where the money goes

UCR is cost recovery for the states, and the statute is specific about the plumbing. Each participating state has a revenue entitlementunder §14504a(g): roughly what it collected under the old Single State Registration System (plus intrastate fees it used to charge interstate carriers), or, for states that never ran SSRS, an allotment capped at $500,000 a year. When you pay, your base state keeps revenue up to its entitlement and forwards the excess to the depositorythe board designates. Under §14504a(h) the depository first tops up, pro rata, states that collected less than their entitlement; then pays the administrative costs of the Plan and the Agreement; and holds any remainder, which reduces the fees set for the following year.

The states, in turn, made a promise to get in. Section 14504a(e) required each participating state’s plan to show that UCR revenue “shall be used for motor carrier safety programs, enforcement, or the administration of the UCR plan and UCR agreement.” That is the trade at the center of the program: the carriers accept one annual fee in place of a patchwork of state registrations and credentials, and the states get funded enforcement without being allowed to hang another cab card on the truck. Forty-one states take part today; Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, and the District of Columbia do not, though carriers based there still owe UCR through a participating base state.

What the Plan is not

It is not FMCSA. FMCSA holds one seat on the board and publishes the fee rule, but it does not collect UCR, and your UCR status does not appear in SAFER. It is not a state agency, though state officials make up most of the board and your base state enforces and audits. It is not a private company, and no private company — including this one — is affiliated with it; the Plan requires filers that use its system to say so in writing. And it does not mail invoices from .com domains or phone for card numbers. Its addresses are plan.ucr.gov and ucr.gov, its number is 1-833-UCR-PLAN, and anything else claiming to be it belongs in the UCR filing scams guide.

Bottom line: the Unified Carrier Registration Plan is the 15-member state-federal-industry board, created by 49 USC 14504a, that administers the UCR Agreement, recommends the fees the Secretary of Transportation sets, and runs ucr.gov. Your fee is credited to your base state and pooled through a depository, and every state that takes it has promised to spend it on motor carrier safety and enforcement.
