What is UCR (Unified Carrier Registration)?
UCR is a federally mandated annual registration for anyone operating commercial motor vehicles in interstate commerce — carriers, brokers, freight forwarders and leasing companies. You pay a fee based on your power-unit count (starting at $46), and participating states enforce it at roadside. For 2026, pay before January 1, 2026.
Who must register for UCR
Any motor carrier — private or for-hire — operating commercial vehicles across state lines (interstate or international commerce). That includes one-truck owner-operators, for-hire passenger carriers, leasing companies that supply vehicles to interstate carriers, freight forwarders, and brokers who arrange interstate shipments. Even a single interstate trip in the year creates the obligation.
Who is exempt
Carriers that operate exclusively within one state (intrastate-only) and never cross state lines. Businesses that move only their own property within a single state, not for hire. And federal, state, local and tribal government agencies. If you're unsure, run a free check — EasyUCR confirms whether you actually need to register before you pay anything.
How the fee works
Your fee is tiered by power units — self-propelled commercial vehicles (tractors, straight trucks, buses). Trailers don't count. The count comes from the most recent MCS-150 on file. Brokers and leasing companies without vehicles pay the lowest $46 bracket.
How EasyUCR makes it painless
Enter your USDOT and our AI Compliance Officer pulls your FMCSA record, computes your exact bracket, opens the official UCR.gov portal, and fills the entire form live while you watch. It stops before payment so you review and submit. You stay the filer — we never submit for you.
Frequently asked questions
Is UCR the same as a USDOT number or MC number?+
No. UCR is a separate annual fee program. Your USDOT and MC numbers identify your business; UCR is a yearly registration and payment tied to your fleet size that interstate carriers must keep current.
Do I need UCR if I only have one truck?+
Yes — if you operate that truck across state lines. Fleet size only determines your fee bracket (one truck falls in the $46 bracket). It does not exempt you.
What happens if I don't register?+
Participating states enforce UCR at roadside. Operating without active UCR can mean fines and citations ($300–$1,000+ per state) and your vehicle can be placed out of service until you register.
