Sell My TruckOverview
The Unified Carrier Registration (UCR) program is the annual registration and fee system for motor carriers, motor private carriers, brokers, freight forwarders, and leasing companies engaged in interstate commerce. It replaced the Single State Registration System (SSRS) and is governed by 49 CFR Part 367, with the UCR Plan providing detailed operational guidance.
UCR registration runs on a calendar year basis, and the fee scale is based on the number of commercial motor vehicles a carrier operates. There are nine fee tiers ranging from carriers with 0-2 vehicles at the lowest rate to carriers with 1,000 or more vehicles at the highest. Brokers and freight forwarders who do not operate CMVs pay a flat fee. All fees are collected by the carrier’s base state and distributed among participating states.
Registration for the upcoming year typically opens in October. Operating in interstate commerce without a current UCR registration is a violation enforceable at roadside and at ports of entry. Officers can check UCR status during inspections, and FMCSA can use non-compliance as part of safety fitness determinations. The UCR is one of several annual compliance obligations — alongside IFTA quarterly filings and IRP registration — that interstate carriers must calendar and track.
Key Provisions
- Annual registration required for all interstate carriers, brokers, and freight forwarders.
- 9 fee tiers based on fleet size — from 0-2 vehicles (lowest) to 1,000 or more vehicles (highest).
- Registration period opens each October for the following calendar year.
- Non-compliance is enforceable at roadside — officers can check UCR status during inspections.
- Fees distributed among participating states based on allocation formula.
Why It Matters to Truck Owners
UCR is an unavoidable annual compliance cost for every interstate carrier. The fees are relatively modest compared to other operating costs, but the consequences of non-compliance — roadside violations and potential operating privilege issues — are disproportionate to the oversight involved. Set a calendar reminder each October to register for the upcoming year before operating into January.
Frequently Asked Questions
Who must register under the UCR program?
Motor carriers, motor private carriers of property or passengers, brokers, freight forwarders, and leasing companies engaged in interstate commerce must register annually under UCR. This includes owner-operators who are their own authority — if you have a USDOT number and operate across state lines, you need UCR registration.
How much does UCR registration cost?
UCR fees vary by fleet size. For the lowest tier (0-2 vehicles), fees are typically under $100. Larger operations pay proportionally more. Exact fee amounts for the current registration year are published by the UCR Plan at ucr.gov and are updated annually — check the current schedule before registering.
Where do I register for UCR?
You register with the UCR program through your base state’s participating agency. Most states allow online registration. The UCR Plan at ucr.gov maintains a directory of state contacts and a registration portal. Owner-operators can also register through their base state’s motor carrier office.
