Unified Carrier Registration(UCR): Complete Guide
for Trucking Businesses
The Unified Carrier Registration (UCR) program is a federally mandated registration system for individuals and companies involved in interstate transportation. Under the UCR program, motor carriers, freight brokers, freight forwarders, and leasing companies must register annually and pay a fee based on the size of their fleet.
The UCR program helps fund state enforcement of motor carrier safety regulations and ensures that interstate carriers remain compliant with federal transportation requirements.
