UCR

Definition

UCR - Unified Carrier Registration - is an annual registration program administered by the Unified Carrier Registration Plan under 49 USC §14504a and 49 CFR Part 367. Every for-hire and private interstate motor carrier, broker, and freight forwarder pays a fee scaled by fleet size to their base state. The 2027 fee tiers under 49 CFR 367.50 range from Bracket 1 ($55 for 0–2 vehicles) to Bracket 6 ($54,165 for 1,001+ vehicles), about 20% above the 2026 schedule ($46 to $44,836) per FMCSA's final rule at 91 FR 56063, effective October 1, 2026. The registration year matches the calendar year, with December 31 as the deadline. UCR is a separate annual registration enforced by participating states; it isn't part of FMCSA's operating-authority grant.
