UCR
Unified Carrier Registration
An annual federal registration and fee system required for motor carriers, brokers, freight forwarders, and leasing companies operating in interstate or international commerce.
UCR (Unified Carrier Registration) is a federally mandated annual registration program that requires motor carriers, motor private carriers, freight forwarders, brokers, and leasing companies to register and pay fees based on fleet size. The UCR program replaced the former Single State Registration System (SSRS) in 2007.
All entities operating in interstate or international commerce must register under the UCR program each year. The fees collected through UCR are used to fund state motor carrier safety programs and enforcement. Fee amounts are determined by a tiered bracket system based on the number of commercial motor vehicles a carrier operates, ranging from the smallest bracket (0-2 vehicles) to the largest (101+ vehicles).
Registration must be renewed annually, and the registration period typically opens in the fall for the following calendar year. Failure to register can result in fines during roadside inspections or compliance reviews. Some states actively enforce UCR compliance and can issue citations to carriers that are not properly registered.
