Quick answer
BOC-3 is a one-time federal filing under 49 CFR §366 that names process agents in every state to accept legal papers for you. UCR is an annual interstate registration fee under 49 CFR Part 367, due December 31 and tiered by fleet size ($55 to $54,165 for 2027). Every for-hire interstate carrier owes both.

BOC-3 is a one-time federal filing under 49 CFR §366 that designates process agents in every US state to accept legal service on your behalf. UCR is a separate annual fee under 49 CFR Part 367 that every for-hire interstate carrier, broker, and freight forwarder pays through their base state. BOC-3 is required before FMCSA grants your MC authority; UCR is a separate annual registration enforced by participating states and isn’t part of FMCSA’s operating-authority grant. Different purpose, different law, different cadence.
What does each filing actually do?
BOC-3 (Designation of Process Agents) satisfies 49 USC §13304 and its implementing regulation at 49 CFR §366.1T–§366.6T. Every interstate motor carrier, broker, and freight forwarder must have an agent authorized to accept court papers and regulatory notices in every state where the carrier operates. The BOC-3 form is the single filing that documents those agents with FMCSA. For volume trends, see the BOC-3 filing statistics from FMCSA’s Motus data.
UCR (Unified Carrier Registration) was created by the Unified Carrier Registration Act of 2005 (Pub. L. 109–59) and is codified at 49 USC §14504a with implementing regulations at 49 CFR Part 367. It funds federal and state motor-carrier safety enforcement by collecting an annual fee from every interstate entity, tiered by fleet size.
One-liner distinction
BOC-3 answers “where do we send legal papers?” UCR answers “have you paid this year’s enforcement fee?”
How much do BOC-3 and UCR cost?
BOC-3 is a flat one-time fee. We charge $75 at fastboc3filing.com and the designation stays valid for the life of your authority as long as your process-agent relationship continues - no annual renewal.
UCR is tiered by fleet size and renewed every year. The 2027 schedule under 49 CFR 367.50 - adopted by FMCSA’s final rule at 91 FR 56063 (published September 1, 2026; effective October 1, 2026), about 20% above 2026 - with the 2026 fee in parentheses, is:
- Bracket 1: 0–2 vehicles - $55 ($46 in 2026)
- Bracket 2: 3–5 vehicles - $167 ($138)
- Bracket 3: 6–20 vehicles - $333 ($276)
- Bracket 4: 21–100 vehicles - $1,163 ($963)
- Bracket 5: 101–1,000 vehicles - $5,548 ($4,592)
- Bracket 6: 1,001+ vehicles - $54,165 ($44,836)
| Bracket | Vehicles | 2027 fee | 2026 fee |
|---|---|---|---|
| Bracket 1 | 0–2 | $55 | $46 |
| Bracket 2 | 3–5 | $167 | $138 |
| Bracket 3 | 6–20 | $333 | $276 |
| Bracket 4 | 21–100 | $1,163 | $963 |
| Bracket 5 | 101–1,000 | $5,548 | $4,592 |
| Bracket 6 | 1,001+ | $54,165 | $44,836 |
2027 schedule per 49 CFR 367.50 (final rule 91 FR 56063; a single increase that holds until a future rulemaking). 2026 schedule per 49 CFR 367.40. 2027 registration opened October 1, 2026; a late 2026 registration still pays the 2026 fee. Fees are annual and renewed every year.
Our service fee for UCR at fastucrfiling.com is inclusive - no add-ons - and your UCR is filed the same business day.
When is each filing due?
BOC-3 is filed once. You only refile if you change legal business name, change process-agent service, or voluntarily revoke the prior designation. FMCSA holds the latest filing on record indefinitely.
UCR opens for registration every October 1 and is enforceable January 1 of the next registration year. UCR is a separate annual registration enforced by participating states; it isn’t part of FMCSA’s operating-authority grant.
Who needs each filing, and who doesn't?
BOC-3 is required for every entity that holds interstate operating authority from FMCSA: for-hire motor carriers, freight brokers, and freight forwarders. Private carriers (those hauling their own goods and not holding for-hire MC authority) generally do not file a BOC-3 because they don’t have an operating authority docket to activate.
UCR is required for every interstate for-hire carrier, private carrier, broker, leasing company, and freight forwarder operating a commercial motor vehicle in interstate commerce. The scope and definitions in 49 USC §14504a(a) are broad - UCR applies even to single-truck owner-operators and even to private fleets that wouldn’t touch a BOC-3.
The overlap trap
Many new carriers think paying one filing covers both. It doesn’t. BOC-3 is required before FMCSA grants your MC authority. UCR is a separate annual registration enforced by participating states; it isn’t part of FMCSA’s operating-authority grant.
What happens if you miss each filing?
Missing BOC-3: your MC authority never activates. FMCSA holds your application in the “BOC-3 required” status indefinitely, which means you can’t legally haul, can’t post on load boards, and brokers flagging you on Carrier411 won’t work with you. No fine - but no revenue either. If FMCSA already deactivated, see our authority reinstatement process.
Missing UCR: 49 U.S.C. §14504a lets participating states enforce UCR at weigh stations and roadside, and those states can assess civil penalties. UCR is a separate annual registration enforced by participating states; it isn’t part of FMCSA’s operating-authority grant. UCR sits alongside other recurring federal obligations like the MCS-150 biennial and Form 2290 HVUT.
