Does Indiana require a USDOT number for intrastate trucking?

Yes for many operations. Indiana sets its own intrastate rule on top of the federal interstate one, and the sourced fact rows on this page show the exact trigger and the exemptions the state publishes. Interstate work triggers the federal requirement regardless of the state rule.

Is the Indiana ID Number the same as a USDOT number?

No. The USDOT number is the federal safety identifier issued by FMCSA; the state number is a separate state credential issued by the state agency named on this page, and the two are linked during the state application. A carrier subject to both rules holds both.

Do I have to pay a filing service to get a USDOT number?

No. You can register directly with FMCSA yourself, and the state credential applications on this page go straight to the state agency through the portal it names. Third-party filing services resell those same applications; nothing on this page requires one.

Where do these facts come from?

Every requirement, threshold, and portal on this page renders from a state agency page, a statute, or an FMCSA publication cited beside the fact. When an agency publishes no figure, the field says so instead of guessing.

Indiana DOT Number: Who Needs One and How to Get It

By Evan Reid, Founder of Haul Handbook · Updated Aug 9, 2026

The Indiana intrastate rule

FMCSA requires a USDOT number for interstate operations everywhere; the rows below show what Indiana adds for carriers that never leave the state. Our state DOT number requirements table holds the same answer for every state. A field reading "Not confirmed" means the agency publishes no figure.

USDOT for intrastate carriers: Yes
Weight trigger: Indiana sets no weight floor. The Department of Revenue's own checklist routes an intrastate for-hire carrier whose vehicles rate under 10,000 pounds to the same Form IOA-1 for an Indiana ID Number rather than a USDOT number, so the smallest intrastate operator still files. Form IOA-1 asks the applicant to check every gross vehicle weight rating band from under 10,000 pounds up through 26,001 pounds and over.
Statute: IC 8-2.1-24-15; IC 8-2.1-24-21

Indiana does not treat the USDOT number as a federal-only credential. State Form IOA-1, Intrastate Operating Authority, is the route by which an Indiana intrastate carrier obtains or renews a USDOT number, and IC 8-2.1-24-21 requires a motor carrier to display a United States Department of Transportation number, or any other identification the department requires, on or in each motor vehicle it operates. Only the smallest intrastate for-hire property carriers, whose vehicles rate under 10,000 pounds, take an Indiana ID Number in its place.

The Indiana ID Number

The federal number is not the whole story in Indiana: the state issues its own carrier credential, and the two are tied together during the state application covered on the Indiana intrastate authority page.

State carrier number: Indiana ID Number
Issued by: Indiana Department of Revenue, Motor Carrier Services
USDOT number required first: No
Display rule: IC 8-2.1-24-21 requires a motor carrier to display a United States Department of Transportation number, or any other identification the department requires, on or in each motor vehicle it operates. IC 8-2.1-22-42 adds a parallel duty for an intrastate carrier regulated under the passenger and household goods chapter, requiring identification displayed in the method prescribed by the department's rules on each motor vehicle it operates, and makes a violation a Class C misdemeanor.

The Indiana ID Number is the alternative to a USDOT number, not a credential layered on top of one. It goes to an intrastate for-hire carrier hauling someone else's property whose vehicles have a gross vehicle weight rating or combined gross vehicle weight rating of less than 10,000 pounds, on the same Form IOA-1 every other intrastate carrier uses. Because Form IOA-1 is itself how an Indiana intrastate carrier gets a USDOT number, no existing federal number is a precondition of the filing.

Where an Indiana carrier enrolls

Both filings go directly to the issuing agency; how the federal one works is covered step by step in our guide to getting a USDOT number. Filing services resell these same applications, so the rows below name the direct channel first.

USDOT number: Intrastate carriers obtain and renew the number on State Form IOA-1 with the Indiana Department of Revenue, Motor Carrier Services. A new interstate carrier, broker, leasing company or freight forwarder instead files federal Form MCS-150 and registers through the Unified Carrier Registration system. (registration site)
USDOT application fee: No fee is stated for the Form IOA-1 filing on the Department of Revenue checklist, on the form itself, or in IC 8-2.1-24, so none is recorded. The charge in Indiana's intrastate system sits on the passenger and household goods certificate instead.
State agency: Indiana Department of Revenue, Motor Carrier Services
State portal: Motor Carrier Services (Form IOA-1 filed online or by mail; renewals accepted online)

Everything sits with one agency. Motor Carrier Services runs intrastate registration and authority alongside oversize and overweight permitting, IFTA, the intrastate Motor Carrier Fuel Tax, the International Registration Plan and base plate registration. Questions on USDOT numbers and UCR go to the same office on 317-615-7200 or [email protected].

Nobody has to pay a filing service. The checklist links straight to the form and to the UCR registration portal, and Motor Carrier Services now takes intrastate operating authority renewals online.

Once a number is active, anyone can pull the public record behind it; our DOT number lookup guide shows how to read that snapshot the way brokers and enforcement do.

The state registration triggers behind it

These are the operations that pull a carrier into Indiana's own motor carrier registration, where the DOT number rules above attach. The full credential, fees, and insurance filings live on the Indiana intrastate authority page.

Weight trigger: Indiana sets no weight floor on the intrastate registration. The Department of Revenue's own checklist routes intrastate for-hire carriers whose vehicles rate under 10,000 pounds to the same Form IOA-1, for an Indiana ID Number rather than a USDOT number, so the smallest intrastate operator still files. Form IOA-1 asks the applicant to check every gross vehicle weight rating band from under 10,000 pounds up through 26,001 pounds and over.
For-hire only: No
Hazmat: A private carrier of hazardous materials operating only in Indiana files Form IOA-1 and an insurance Form E, the same route as an intrastate for-hire carrier. A private carrier of nonhazardous materials files Form IOA-1 alone and has no renewal obligation.

Where the number fits in the Indiana launch

Registration numbers come early: they exist before insurance binds and before the first load. For the full order of operations, from entity to authority to plates, work through start a trucking company in Indiana, and keep the Indiana trucking hub handy for the rest of the state's credentials.
