Unified Carrier Registration (UCR) Fees in California

Who Must File in California

Any California business that moves vehicles across state lines or international borders needs to file. The requirement covers:

• For-hire and private property carriers operating vehicles with a Gross Vehicle Weight Rating (GVWR) above 10,000 pounds
• Passenger carriers that transport more than 10 people, counting the driver
• Haulers of hazardous materials that require placards
• Freight forwarders, brokers, and leasing companies that arrange interstate transportation, even when they own no power units

Carriers that operate only within California are not required to register for UCR.

How California Carriers File

Since California does not collect UCR fees itself, fleet operators register through a participating base state, such as Arizona, or through the national UCR portal. The process has five steps:

• Confirm USDOT status: The active USDOT number should match the carrier’s current classification.
• Count the fleet: The carrier totals the qualifying commercial motor vehicles (power units) it operated during the designated 12-month period.
• Submit the registration: Business details are entered into the national UCR system.
• Pay the fee: Payment can be made online by credit card or Electronic Funds Transfer (EFT).
• Keep proof of filing: Official receipts should be stored so they can be shown during roadside inspections or federal audits.

UCR Fee Schedule

The Federal Motor Carrier Safety Administration (FMCSA) sets UCR fees according to fleet size.

Deadlines and Penalties

Registration for the coming calendar year opens on October 1, and payment is due by December 31. A carrier that runs an interstate fleet without an active UCR filing may face heavy fines, vehicle detention, and out-of-service orders issued by enforcement officers in any state.
