How to File Your UCR Registration

Filing UCR is simpler than most FMCSA paperwork. There are three questions to answer — what is my base state, how many vehicles did I operate in interstate commerce last year, and which portal am I filing through — and after that it's a short online form and a credit card charge. For the foundational regulatory context, see the what is UCR registration guide.

Step 1: Determine Your Base State

Your base state is where your UCR fees are paid and remitted to the participating states' treasury pool. If your principal place of business is in one of the 41 participating states, that is your base state automatically. If you are in a non-participating state — Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, or the District of Columbia — you select a neighboring participating state during filing. A Florida carrier commonly picks Georgia; an Oregon carrier picks Washington or California.

Step 2: Count Your Fleet

UCR fees are tiered by the number of self-propelled commercial motor vehicles you owned or operated in interstate commerce. Count power units honestly: owned and long-term-leased trucks and tractors count; trailers do not, because the UCR statute defines a CMV as a self-propelled vehicle (49 USC §14504a(a)(1)). You may base the count on your most recent MCS-150 or on the 12-month period ending June 30 of the year before the registration year. If you are a broker or forwarder with no trucks, your count is zero and you file at Tier 1 (0–2 vehicles). The full counting rules — leased units, the 10,001-pound line, the intrastate exclusion — are in the how to count your UCR fleet guide.

Step 3: Choose Your Filing Path

There are two ways to file:

1. Direct at ucr.gov. The National UCR Registration System accepts filings from carriers, brokers, and forwarders at no service-fee markup. You pay only the federal UCR fee. The portal requires you to identify your entity, select a base state, declare your fleet count, and pay by card or ACH.
2. Through a third-party filer. A service like FastUCR submits the filing, handles base-state routing for non-participating carriers, and gives you a single dashboard to track renewals. The trade-off is a flat professional service fee on top of the federal portion.

After You File

Electronic filings post to the National UCR Registration System once payment is confirmed. Once the record is active, roadside enforcement can verify it nationwide. Keep your payment receipt and a copy of the registration confirmation; many carriers keep a PDF in the cab so a driver can show it if a scale house screen has stale data.

For a detailed look at the fee tiers themselves, see the UCR tiers and fees guide. If you are filing from a non-participating state, the UCR base state rules guide walks through the selection logic.
