UCR Registration 2026: Fee Tiers, Deadlines, and the 48-State Enforcement Grid
The Unified Carrier Registration fee is due every calendar year. Miss the December 31 deadline and roadside inspectors in participating states will write a violation that posts to your CSA record. Here is the 2026 fee schedule and the exact renewal process.
UCR is a tiny filing by dollar value — most owner-operators pay under $100 — but a skipped year shows up at the weigh station faster than any other deadline. Forty-one states check UCR at roadside. Inspectors have a live database. A missing registration is a fast write-up and, if the driver also has any HOS imperfection, a potential out-of-service order.
How UCR replaced the old Single State system
Before 2007, carriers registered fees individually with every state they operated in. Congress replaced this patchwork with the Unified Carrier Registration Agreement — one payment to the base state, revenue shared among participating states. The program funds MCSAP grants and state enforcement budgets.
2026 fee tiers
Fees are based on the number of power units in the fleet as reported on the most recent MCS-150. Leased operators (Authorized Hauler, Exempt for Hire, Private) use the same table.
| Power units | 2026 fee |
|---|---|
| 0 – 2 (and broker-only) | $46 |
| 3 – 5 | $138 |
| 6 – 20 | $276 |
| 21 – 100 | $963 |
| 101 – 1,000 | $4,592 |
| 1,001 or more | $44,836 |
The registration window and deadline
- October 1. Registration opens for the following calendar year at ucr.gov.
- October – December. Early payment is penalty-free. No discount for paying early, but also no downside.
- December 31. Deadline for the upcoming year. Payment after this date is still accepted but the carrier is technically unregistered on January 1.
- January 1. Enforcement begins. A carrier caught operating without a current UCR in a participating state gets a citation — usually a civil penalty ranging from $100 to $5,000 depending on state and repeat-offender status.
Participating and non-participating states
The 41 participating states share UCR revenue and enforce the requirement. The 11 non-participating states do not enforce UCR at roadside, but carriers still must pay if they operate interstate commerce touching any participating state.
Registering for the first time
- Go to
ucr.gov. Click "Register" on the dashboard. - Enter the USDOT number and MC number. The system pulls company details from MCMIS.
- Confirm the power-unit count. Adjust if the MCS-150 is stale.
- Select the base state. This is where the fee revenue accrues; it should match the carrier's principal place of business.
- Pay by credit card or ACH. Confirmation emails arrive within minutes.
Renewals — 10-minute version
- Log into ucr.gov using the carrier's USDOT and the password set at initial registration.
- Verify the current power-unit count.
- Click "Renew for 2026."
- Pay. Confirmation number is the only proof of compliance that matters at roadside.
What happens if you get cited
A UCR violation at roadside lands on the driver's inspection report with citation 392.2 UCR (state code varies). The violation itself carries no CSA weight in the FMCSA Safety Measurement System, but the inspection itself counts toward the inspection denominator for other BASICs, and the state civil penalty is separate from any federal consequence. Most states allow you to clear the citation by paying UCR within 10 days of the inspection.
Where Deadline Safe fits
Deadline Safe tracks UCR as a recurring annual deadline for every monitored USDOT. The first reminder fires on October 1 (the day registration opens), the second on November 15, and the third on December 20, with a final email on the morning of December 31. Pay it in 10 minutes at ucr.gov and move on.
Start a 30-day free trial so the October UCR reminder is already set for you.
Put this on autopilot
Deadline Safe watches FMCSA every 15 minutes and texts you the second anything changes. 30 days free, no credit card, no FMCSA login.
