Unified Carrier Registration (UCR)

Unified Carrier Registration is an annual federal program that requires interstate carriers, brokers, freight forwarders, and leasing companies to register and pay a fee to their base state. It is administered by a board of participating states, not directly by FMCSA, and it replaced the older single-state registration system. The fee funds state safety-enforcement programs; the registration itself is a compliance obligation, separate from a carrier's operating authority and its MCS-150 filing.

How the fee is set

The fee is bracketed by fleet size, measured in power units. It is a flat amount per bracket, the same for every carrier in that bracket nationwide. For the 2026 registration year (unchanged from 2025), the published brackets are:

• 0 to 2 power units: about $46
• 3 to 5 power units: about $138
• 6 to 20 power units: about $276
• 21 to 100 power units: about $963
• 101 to 1,000 power units: about $4,592
• 1,001 or more power units: about $44,836

Brokers, freight forwarders, and leasing companies that operate no power units of their own pay the lowest bracket. The amounts are set per registration year, so anchor any figure to a year; the board can adjust the schedule.

What it does and does not tell you

UCR compliance is a housekeeping signal, not a safety or authority signal. A current registration says a carrier met a routine annual obligation; it says nothing about insurance, safety history, or whether the authority is active. It is not a filing fleetfax surfaces as a vetting flag on its own. The datapoints that carry booking weight are authority status, insurance on file, and inspection history, which live in other parts of the federal record.
