UCR Registration Explained: The Unified Carrier Registration Fee for Interstate and Cross-Border Carriers

UCR registration, short for Unified Carrier Registration, is an annual fee that motor carriers, brokers, freight forwarders and leasing companies pay to operate in interstate or international commerce in the United States. Under this federal-state program, participating states share the money to fund motor carrier safety enforcement. UCR replaced the old Single State Registration System. You get no plate, card or decal: the registration sits against your USDOT number in a national database, and roadside officers check that database.

Any carrier with a USDOT number that runs a commercial motor vehicle across a state line or the US border must register, for-hire or private, as must any broker, freight forwarder or leasing company in interstate commerce. Canadian and Mexican carriers operating in the US are included and register through a base state, and the program treats them like a US carrier. Purely intrastate carriers are exempt. A handful of states do not participate in UCR, but a carrier based in one still registers if it operates interstate. Its base state is a participating state where it has an office or operating facility, or else one near its principal place of business chosen from the UCR Plan's list.

Your fee depends on how many commercial motor vehicles you ran interstate, counted, at your choice, from your most recently filed MCS-150 form or as the total you owned or operated in the 12 months ending June 30 of the previous year. The brackets are zero to two vehicles, three to five, six to twenty, twenty-one to one hundred, one hundred one to one thousand, and over a thousand. Brokers and forwarders without vehicles pay the lowest bracket. The UCR board sets the amounts each year. For the 2027 registration year, effective October 1, 2026, the fees in US dollars are $55 for zero to two vehicles, $167 for three to five, $333 for six to twenty, $1,163 for twenty-one to one hundred, $5,548 for one hundred one to one thousand, and $54,165 for over a thousand. Registration for the coming year opens in the autumn, and the fee must be paid before January 1 of the registration year, the enforcement date the UCR Board has recommended in recent years.

Carriers most often forget the annual renewal, since nothing visibly expires, or count the fleet wrong, since the count must come from the latest MCS-150 or the 12 months ending June 30. A telematics vehicle group of the units that cross state lines gives you an accurate count, and it is the same group that carries IRP plates and files IFTA.

The essentials in one place. The UCR board sets fee amounts each year, so confirm them when you register.
