Does Arkansas require a USDOT number for intrastate trucking?

Not as a general rule for carriers that operate only inside Arkansas. Federal rules can still require a USDOT number for your operation, including interstate trips and some hazardous materials loads.

Is the Arkansas M-Number (ARK. M No.) the same as a USDOT number?

No. The Arkansas M-Number (ARK. M No.) is a separate state credential from the federal USDOT number. The table above names who issues it and whether you need the USDOT number first.

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?

Each row cites the agency page, statute or rule it was read from, with the date the record was last verified. A field this guide could not confirm is labeled Not confirmed rather than filled with a guess.

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

By Haul Handbook editorial team· Updated Sep 27, 2026

The Arkansas intrastate rule

Federal USDOT registration depends on the vehicle and operation. The rows below show what Arkansas requires for carriers operating inside the state. Our state DOT number requirements table holds the same answer for every state. A field reading "Not confirmed" means this guide has no verified figure for that field.

USDOT for intrastate carriers: No general requirement
Weight trigger: Arkansas sets no state weight trigger for a USDOT Number because it does not require the number for intrastate operation. The federal rule still reaches intrastate carriers hauling hazardous materials in the types and quantities that need an FMCSA safety permit (49 CFR 385.403).
On FMCSA's intrastate list: No
Statute: No Arkansas statute requiring a USDOT Number for intrastate operation was found in the Motor Carrier Act sections read for this site (Ark. Code Ann. §§ 23-13-206, 23-13-207, 23-13-265), so none is cited.

Arkansas is not on FMCSA's list of states that require their intrastate commercial motor vehicle registrants to obtain a USDOT Number. ARDOT's intrastate permit application (Form AR RS 1) lists the U.S. DOT No. only among identification numbers marked if applicable, and asks for a DOT safety rating or, without one, a notarized statement of intent to comply with DOT safety regulations.

The Arkansas M-Number (ARK. M No.)

Arkansas issues its own carrier credential alongside the federal number. Who needs it, and how it relates to federal registration, is covered on the Arkansas intrastate authority page.

State carrier number: Arkansas M-Number (ARK. M No.)
Issued by: Arkansas Department of Transportation (ARDOT), Legal Division
USDOT number required first: Not confirmed

ARDOT's registration form AR RS 1 and renewal form AR RS 2 each carry an ARK. M No. field, and the order form labels it Arkansas M-Number. ARDOT's pages do not describe how the number is assigned or state that a USDOT Number must come first, so the USDOT prerequisite stays blank.

No Arkansas-specific USDOT marking rule appears on the ARDOT and DFA pages read for this file, so none is asserted.

Where an Arkansas carrier enrolls

Registration goes to the agency that issues each credential; the federal process 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.

Create a user profile, complete identity verification, and create a company account in Motus to apply for a USDOT number and the registrations your operation needs. Claim your existing USDOT record in Motus using the company official’s Login.gov email, then manage registrations or apply for additional authority. See the Motus account guide before opening or claiming your record.

USDOT number: Directly with FMCSA; no Arkansas agency issues the USDOT Number (registration site)
USDOT application fee: Free
State agency: Arkansas Department of Transportation (ARDOT), Legal Division
State portal: ARDOT Arkansas Intrastate Authority applications page (paper forms)

ARDOT publishes downloadable application packets rather than an online filing portal. General freight carriers mail Form AR RS 1 with Form AR-RS2 and the fees by cashier's check or money order to ARDOT Legal Division, P.O. Box 2261, Little Rock, AR 72203.

Two Arkansas credentials ask for the number on the application: the DFA IRP Unit requires the FEIN and USDOT number of the carrier responsible for safety for apportioned registration, and the Arkansas IFTA application (Form AMFT-71) asks for a USDOT number, or Leased when the vehicle runs under another carrier's authority.

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, and the MC number lookup reads the live record back for a number you type in.

The same number carries your safety history. Every roadside inspection written against it feeds the CSA percentiles a broker's vetting platform reads after it checks your authority and insurance, and a violation recorded in error is corrected through DataQs, not by the state agency that issued the credential above.

The state registration triggers behind it

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

Weight trigger: over 26,000 lb
For-hire only: Yes
Hazmat: Carriers declaring hazardous materials on Form AR RS 1 carry liability of $1 million or $5 million by commodity and vehicle class under 27 CAR § 110-1301(b)(6) (Rule 13.1), and a vehicle placarded for hazardous materials is not covered by the 26,000 pound exemption.

Where the number fits in the Arkansas 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 Arkansas, and keep the Arkansas trucking hub handy for the rest of the state's credentials.
