Home › Guides › New Carrier Setup: What You Must File to Get Started
Starting an interstate trucking operation means a handful of separate federal filings, each with its own agency and its own portal. Here they are in the order they actually happen, so nothing quietly falls through the cracks in your first year.
Almost everything downstream hangs off one thing: your USDOT number. It is the identifier the Federal Motor Carrier Safety Administration (FMCSA) uses to track your safety record, inspections, and audits. If you operate commercial vehicles in interstate commerce over the applicable weight or passenger thresholds, you generally need one before you run a mile.
You apply through the FMCSA registration system at fmcsa.dot.gov. Take your time on the application — you will describe your operation type, your cargo, and how many vehicles and drivers you have. Those answers set your biennial update schedule later, so accuracy matters more than speed. The USDOT number itself is issued at no cost; be wary of third-party sites that charge to "get" one for you.
A USDOT number tells FMCSA who you are. Operating authority — the "MC number" — tells them what you are allowed to do. If you are a for-hire carrier transporting regulated goods or passengers across state lines, you need it. Private carriers hauling their own product, and some exempt commodity haulers, may not — this is a good place to confirm your situation directly with FMCSA rather than assume.
You apply for authority through the same FMCSA registration portal, and there is an application fee per authority type. Because that fee can change, check the current amount on the official site rather than trusting a number you read secondhand. Once you file, there is a mandatory waiting period before authority becomes active, which is why the next two steps need to happen right away.
Two filings actually switch your authority on, and both come from someone other than you. The first is the BOC-3, a designation of process agents — people authorized to receive legal documents on your behalf in each state. In practice a blanket process-agent company files this electronically for you for a small one-time fee. You cannot activate authority without it.
The second is proof of insurance. Your insurance provider files the required forms (liability, and cargo or a bond depending on your operation) directly with FMCSA on your behalf. Line up your insurer early and tell them you need federal filings, not just a policy — the coverage and the filing are two different things. When your BOC-3, your insurance, and the waiting period are all satisfied, your authority goes active.
The Unified Carrier Registration (UCR) is an annual program covering carriers, brokers, and freight forwarders operating interstate. You register and pay at the official ucr.gov. The fee is tiered by the number of vehicles in your fleet, and the fee schedule is set each year — so treat the exact amount as a look-it-up item, not a memorized one.
UCR opens for the coming year in the fall and is due before you operate in that year. Missing it can mean fines or being placed out of service in enforcement states, and it is easy to forget precisely because it is once a year. This is the kind of recurring, date-driven filing worth putting on a reminder the day you register.
Two more pieces sit outside FMCSA. If you operate a vehicle with a taxable gross weight of 55,000 pounds or more, you owe the federal Heavy Highway Vehicle Use Tax, reported on IRS Form 2290. The tax year runs July 1 through June 30, and for a vehicle you first use in July, the return is generally due by August 31; for a vehicle first put into service later, it is due by the last day of the following month. File at irs.gov and keep the stamped Schedule 1 — you will need it to register plates.
Speaking of plates: interstate operation across multiple states usually means the International Registration Plan (IRP) for apportioned plates and the International Fuel Tax Agreement (IFTA) for fuel-tax reporting. Both are administered through your base state, not FMCSA, so start with your state's department of motor vehicles or motor carrier division.
Your registration is not "set and forget." Under 49 CFR 390.19T, every carrier must update its MCS-150 at least every 24 months, even when nothing has changed, and also whenever key details change. Your specific month comes from your USDOT number: the last digit sets the month (1 = January through 9 = September, and 0 = October), and the second-to-last digit sets the year — odd means odd-numbered years, even means even-numbered years.
Letting this lapse can lead to deactivation of your USDOT number, which puts your operation on hold. If you would rather not do that arithmetic under pressure, the free MCS-150 due-date calculator on this site works it out from your number in a few seconds. DOTDeadline can also remind you before this filing and the other recurring ones above, so a missed date never becomes a shutdown.
New-carrier setup is a sequence, not a single form: USDOT number first, then MC authority if you haul for hire, then the BOC-3 and insurance filings that activate it, plus UCR, IRS Form 2290, and IRP/IFTA through your base state — and finally the MCS-150, which you must update at least every 24 months on a schedule set by your USDOT number's digits. This is general information, not legal or tax advice; DOTDeadline is not affiliated with or endorsed by FMCSA or the IRS, so confirm the current fees, forms, and dates with the official agency before you file.
