The short answer
The federal government charges exactly one fee for interstate operating authority: $300 per authority type, paid to FMCSA when you apply (FMCSA fee FAQ). Everything else people lump into “the cost of an MC number” is either a different filing (BOC-3, UCR, IRP), a state item, insurance, or a service company’s markup.
Here’s the whole stack at a glance for a one-truck interstate carrier. Each line is unpacked below.
| Item | Who you pay | Typical 2026 cost | When |
|---|---|---|---|
| Operating authority application | FMCSA | $300 per authority type | At filing |
| USDOT number | FMCSA | $0 | At filing (same application) |
| BOC-3 process agent | A process-agent company | ~$50–$100 one-time | Within 20 days of register publication |
| Liability insurance filing | Your insurer (files BMC-91/91X for you) | First-year premium is the big cost — see below | Within 20 days of register publication |
| UCR registration | Your base state (via plan.ucr.gov) | $46 for 0–2 trucks | Annually, due Dec 31 |
| IRP apportioned plates | Your base state | Commonly ~$1,500–$2,000/yr at 80,000 lbs | Before running interstate |
| IFTA license + decals | Your base state | Free to nominal, varies by state | Before running interstate |
| Heavy Vehicle Use Tax (Form 2290) | IRS | Up to $550/yr | After first use of the truck |
| Drug & alcohol consortium | A C/TPA | ~$85–$300/yr advertised | Before driving |
| Clearinghouse queries | FMCSA Clearinghouse | $1.25 per query | At hiring (incl. yourself) |
| ELD | An ELD vendor | $0–$50/mo depending on model | Within 8 days of running on hours |
Total it up honestly: the non-insurance startup stack runs roughly $2,500–$3,200, with IRP as the swing item — and then the first-year insurance premium dwarfs all of it combined.
The $300 federal filing fee — the only fee FMCSA charges
FMCSA charges $300 for each operating authority you request, and the fee is non-refundable even if your application is dismissed or rejected (FMCSA). Most new carriers need exactly one (motor carrier of property). If you also want broker authority or household-goods authority, each one is its own $300.
Since the May 2026 cutover, applications go through FMCSA’s new registration system at motus.dot.gov. Two things worth knowing about that system:
- The USDOT number itself is free. Anyone charging you to “get your DOT number” is charging for paperwork you can do yourself in the same application where you request authority.
- MC numbers haven’t been eliminated. You may have read that docket numbers are gone. Per FMCSA’s own registration modernization FAQs, docket numbers were not eliminated at the new system’s launch — phasing them out in favor of USDOT-only identification is a proposal for a future rulemaking. Today you still apply, pay $300 per authority, and your application is published on FMCSA’s daily register as a preliminary grant under 49 CFR Part 365.
One timing fact that matters for your budget: publication on the register is not active authority. There’s a 10-day protest window after your application publishes, and the grant becomes effective by issuance of your certificate only if it’s unopposed and your insurance and BOC-3 are on file (49 CFR 365.115). Plan on roughly 4–6 weeks from submission to active authority (Small Fleet HQ’s post-cutover guide, May 2026) — and you’ll pay several of the fees below during that window, before you can legally haul a load.
BOC-3 process agent: ~$50–$100, one-time
The BOC-3 designates a process agent — someone who can accept legal papers for you — in every state. FMCSA charges nothing for the filing itself, but for carriers it must be e-filed by a process-agent company, so in practice you pay one of them. Current market pricing for a one-time blanket (all-states) filing clusters between about $50 and $100: for example, BOC-3 Process Agents advertises a $50 flat rate and other established filers list $68–$75 one-time (commercial vendors — shop around, the service is a commodity). A few firms instead charge a small annual fee; read which model you’re buying.
Deadline: under 49 CFR 365.109T your process-agent designation and insurance evidence are due within 20 days of your application publishing on the register. Miss it and your application stalls.
Insurance: the fee that decides whether you launch
This is the real cost of authority, and it’s the one nobody can quote you from a table.
What’s federally required for a general-freight property carrier is public liability coverage of at least $750,000, filed electronically by your insurer as a BMC-91 or BMC-91X (49 CFR 387.9). Certain hazmat loads require $5,000,000. Cargo insurance is not federally required for general freight — but in practice brokers won’t load you without it, and $100,000 cargo is the standard ask in 2026 broker packets.
What you’ll actually pay as a brand-new authority: insurance-agency guides published for 2026 put first-year, single-truck new-authority packages (liability + cargo + physical damage) broadly in the $8,000–$20,000 per year range, with new authorities paying substantially more than carriers with 2–3 years of history (American Truckers LLC, FleetGuard USA — both are commercial agencies, so treat the ranges as marketing-adjacent and get your own quotes). Where you land in that range turns on your state, driving record, truck age, radius, and commodity. Get at least three quotes, and make sure each one includes the federal filing — the insurer files the BMC-91/91X directly with FMCSA; you never file it yourself.
Budget note: insurers typically want a down payment before binding, and your authority cannot go active until the insurance filing and BOC-3 are both on record — so this money is due during the application window, not after you start earning.
UCR: $46 for most new authorities
Unified Carrier Registration is an annual fee collected through your base state at plan.ucr.gov. The 2026 fees were held unchanged from 2025 by final rule (Federal Register, April 7, 2026):
| Fleet size (power units) | 2026 UCR fee |
|---|---|
| 0–2 | $46 |
| 3–5 | $138 |
| 6–20 | $276 |
| 21–100 | $963 |
| 101–1,000 | $4,592 |
| 1,001+ | $44,836 |
Registration for each year opens October 1 and fees are due by December 31. Brokers and freight forwarders without trucks pay the lowest bracket. Pay it on the official site — UCR is a favorite hook for lookalike sites that charge a “processing fee” on top.
Truck registrations: IRP, IFTA, and the 2290
These apply only if you’re running your own power unit interstate (a broker-only authority skips this whole section).
IRP (apportioned plates). Your interstate truck registration, split across the states you run. The cost is a formula — each state’s full registration rate weighted by your declared mileage — so there’s no single national price, but industry guides consistently put an 80,000-lb tractor running the lower 48 at roughly $1,500–$2,000 per year (Motor Carrier HQ, IRP Registration Services — secondary sources; your base state’s IRP office will compute the real number). First year uses estimated mileage. This is usually the second-largest check you write after insurance.
IFTA. The fuel-tax license and decals from your base state. The license is free or nominal in most states; the real money is the quarterly fuel-tax true-up afterward, which nets against tax already paid at the pump. Budget the paperwork, not a big fee. Four states (Kentucky, New York, New Mexico, Oregon) layer their own weight-distance taxes on top — registering is free or cheap, but they’re a per-mile operating cost to know before pricing freight in those lanes.
Heavy Vehicle Use Tax (IRS Form 2290). Federal tax on trucks with a taxable gross weight of 55,000 lbs or more: $100 plus $22 per 1,000 lbs over 55,000, capped at $550/year at 75,000 lbs and up (IRS Form 2290 instructions). Due by the last day of the month after the month you first put the truck on the road, prorated for partial years. You’ll need the stamped Schedule 1 to complete your IRP registration in most states, so don’t leave this for later.
Driver and compliance items
Small line items, but they’re mandatory and they’re due before you drive:
- Drug & alcohol testing program. As an owner-operator you must be enrolled in a random-testing consortium — you can’t administer your own program. Advertised 2026 consortium pricing for a single driver runs from about $85 to $300 per year depending on what’s bundled (Vertical Identity’s published breakdown is one example; all such pricing is vendor-advertised). A pre-employment drug test — required even when the employee is you — typically adds $30–$85 at local collection sites.
- Clearinghouse queries. Registration is free; queries cost a flat $1.25 each (FMCSA Clearinghouse query plan). You need a pre-employment full query for every driver you put in a truck, including yourself.
- DOT physical. If your medical certificate is current, $0. If you need a new one, clinics commonly charge $50–$150 (2026 cost surveys — call your local occupational-health clinic for the real price).
- ELD. Required once you’re running on hours of service. 2026 pricing spans $0/month devices (one-time hardware purchases like the Garmin eLog) up to $20–$50/month subscriptions for mainstream platforms (GPS Insight’s 2026 cost breakdown — vendor source). Check any device against FMCSA’s registered-ELD list before buying; revocations happen. Compare ELD options.
Fees you can skip
- “DOT number registration” services. The number is free. The unified application at motus.dot.gov covers it.
- Authority filing services charging $300–$900 on top of the federal fee. The application is a form. If your operation is plain-vanilla — one authority type, no prior FMCSA history — filing yourself costs an evening, not $900.
- Anything sold by cold call the week you file. Your application is public the day it hits the register — that’s how compliance telemarketers and fraudsters both find brand-new authorities. Before paying anyone who called you, check their claims against the actual register with our free verify tool.
- Broker authority “packages,” if you’re a carrier. That’s a separate $300 authority plus a $75,000 surety bond or trust (49 CFR 387.307). Add it when you have brokerage business, not speculatively.
What it adds up to: a one-truck sample budget
Mid-range figures from the sections above, for a single tractor at 80,000 lbs running the lower 48:
| Line | Mid-range figure |
|---|---|
| FMCSA authority application | $300 |
| BOC-3 blanket filing | $75 |
| UCR (0–2 trucks) | $46 |
| IRP apportioned plate (estimated) | $1,750 |
| Form 2290 HVUT | $550 |
| Drug & alcohol consortium + pre-employment test | $150 |
| Clearinghouse query | $1.25 |
| DOT physical (if needed) | $100 |
| Subtotal before insurance | ~$2,970 |
| First-year insurance premium | $8,000–$20,000 (quote-dependent) |
State business formation (LLC or corporation) is on top of this and varies by state — check your Secretary of State’s actual fee schedule rather than a filing service’s bundle price. And once you’re active, the next costs are operational: load board access (DAT is the default for most new authorities), fuel, and factoring if you use it.
When each payment is actually due
The sequence matters more than the total, because several payments land before you can earn:
- Day 0 — application. $300 to FMCSA at filing.
- Register publication. Your application publishes on FMCSA’s daily register as a preliminary grant. A 10-day protest window opens (49 CFR Part 365); for new carriers it’s almost always quiet.
- Within 20 days of publication. Insurance filing (BMC-91/91X, made by your insurer — premium down payment due now) and BOC-3 must be on record (49 CFR 365.109T).
- Issuance. Unopposed application + filings on record = authority becomes effective when your certificate issues (49 CFR 365.115). Roughly 4–6 weeks end to end in current practice.
- Before the first dispatch. IRP, IFTA, 2290, consortium enrollment, Clearinghouse query, ELD.
- By December 31. UCR for the coming year.
The honest number: $300 to the government for the authority itself, roughly $3,000 in surrounding mandatory filings for a one-truck operation, and an insurance bill that depends on your record and your state. Get the insurance quote first — it decides whether the rest of the list is worth paying.
