Concierge Compliance CareHow to Get a DOT Number in Illinois
People search for a "Illinois DOT number", but the number itself is a federal USDOT number. Here is how Illinois carriers get one, and where Illinois's own rules come in.
Not a government site. This site is not affiliated with FMCSA, the U.S. Department of Transportation, Login.gov, or any government agency. You can register with FMCSA yourself at motus.dot.gov, and there is no FMCSA charge for a USDOT number. Paid filing help from us is optional.

USDOT numbers are issued by FMCSA through Motus at motus.dot.gov. That is true in Illinois and every other state. FMCSA does not charge for the USDOT number. This site is an independent guide and is not affiliated with FMCSA or any Illinois agency.
When a Illinois carrier needs a USDOT number under federal rules
If you operate commercial vehicles in interstate commerce and meet FMCSA's vehicle tests, such as a gross vehicle weight rating, gross combination weight rating, gross vehicle weight or gross combination weight of 10,001 pounds or more, whichever is greater, you need a USDOT number. Hauling into or out of Illinois, or moving freight inside Illinois as part of a shipment from or to another state, counts. See Do you need a DOT number? for the full tests.
Illinois is not on FMCSA's list for in-state carriers
FMCSA keeps a list of states that require their intrastate commercial vehicle registrants to get a USDOT number. Illinois was not on that list when we checked on November 15, 2026 (Do I Need a USDOT Number?, last updated September 3, 2025).
That does not mean Illinois has no rules for in-state carriers. Illinois sets its own registration, permit and safety requirements, separate from FMCSA's list. We do not summarize them here. Confirm with the responsible Illinois state agency before you operate. Our intrastate guide explains how federal and state rules fit together.
Federal rules still apply on their own terms: interstate operations that meet FMCSA's tests need a USDOT number, and so do intrastate hazardous materials carriers whose loads require a federal safety permit.
The federal steps, in short
- Create a free Login.gov account. Why it takes time: A separate sign-in with multi-factor authentication.
- Complete identity verification with a government-issued ID and a photo of yourself. Why it takes time: Photo ID plus a photo of yourself; problems here stop the application.
- Create your Motus company account. Why it takes time: Company details that must match your state and IRS records.
- Apply for the USDOT number, and for operating authority if your operation needs it. Why it takes time: A multi-part application; authority adds a fee, a BOC-3 and insurance filings.
Four steps, two sign-ins and an ID check before you even reach the application. Want help?

USDOT number vs operating authority
If you haul regulated freight for others across state lines for pay, you generally need federal operating authority as well. Read USDOT number vs MC number. In-state-only for-hire questions belong with Illinois's agency.
After you have the number
Keep your record current. Interstate carriers must file a biennial update with FMCSA, and changes to your name, address or operation should be updated promptly. Our sister site dotnumberhelp.com covers keeping a number active.

Frequently asked questions
Do I get a Illinois DOT number or a USDOT number?
The identifier is a USDOT number issued by FMCSA. Illinois may also have its own state credentials; confirm with the state agency.
Is Illinois on the list of states that require a USDOT number for in-state carriers?
Not as of our November 15, 2026 check (page last updated September 3, 2025). Illinois may still have its own rules for in-state carriers, so confirm with the state agency, and check Do I Need a USDOT Number? for the current list.
Is it free in Illinois?
FMCSA does not charge for a USDOT number, in Illinois or anywhere else. Any state fees are separate; confirm them with Illinois.
Where do I apply?
In Motus at motus.dot.gov.
Do I need an MC number to haul inside Illinois only?
Federal operating authority is about for-hire interstate work. In-state-only for-hire rules are set by Illinois. The USDOT Wizard can help sort out the federal side.
