The Tennessee intrastate rule
FMCSA requires a USDOT number for interstate operations everywhere; the rows below show what Tennessee 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.
- Weight trigger
- No weight trigger is recorded because Tennessee sets no intrastate USDOT number requirement for one to attach to. The weight line that does matter to a Tennessee intrastate carrier is the 10,001 pound split in the intrastate authority insurance schedule, which sits on the intrastate authority page.
- Statute
- No Tennessee statute is cited here, because Tennessee imposes no USDOT number requirement on intrastate carriers and issues no state carrier number for a statute to create. The statute behind the state permit an intrastate for-hire carrier does need is recorded on the Tennessee intrastate authority page with its own source.
Tennessee does not appear on FMCSA's published list of states that require their intrastate commercial motor vehicle registrants to obtain a USDOT number. The Application for Intrastate Authority (Form RV-F1315501) does print a USDOT field in Section B, but neither the form, the Department of Revenue intrastate authority page, nor the March 2026 Motor Carrier Education Guide states that an intrastate-only carrier must hold a number. Interstate operation is a separate matter: a carrier crossing a state line is covered by the federal rule, not by anything Tennessee publishes.
No separate Tennessee carrier number
Tennessee markets no state carrier number of the CA number or TxDMV number kind. What the state issues after an intrastate authority application is approved is an Intrastate Permit Card, one for each vehicle registered on the account. left blank plus this note rather than left blank, because the absence is the answer a carrier is looking for.
Where a Tennessee 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
- Directly with FMCSA at fmcsa.dot.gov/registration (registration site)
- USDOT application fee
- No Tennessee agency page states a USDOT application fee, and no Tennessee agency issues the number, so no amount is recorded here.
- State portal
- Tennessee Taxpayer Access Point (TNTAP)
Intrastate authority, IFTA, and IRP accounts are all opened, renewed, and managed in TNTAP, and supporting documents upload to the same account. Motor carrier questions go to [email protected] or (615) 399-4265.
The Motor Carrier Education Guide defines the USDOT number as a carrier-specific number issued by the Federal Motor Carrier Safety Administration and used as a census number for tracking motor safety compliance. Tennessee collects the number on its IRP and IFTA applications and on the intrastate authority form; it never issues one.
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 Tennessee's own motor carrier registration, where the DOT number rules above attach. The full credential, fees, and insurance filings live on the Tennessee intrastate authority page.
- Weight trigger
- Tennessee publishes no gross weight threshold for intrastate authority itself. The Department of Revenue page and the Motor Carrier Education Guide define the requirement by the kind of operation, not by vehicle weight. Weight only enters through the insurance schedule, which splits at 10,001 pounds. Left blank rather than inventing a weight trigger.
Where the number fits in the Tennessee 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 Tennessee, and keep the Tennessee trucking hub handy for the rest of the state's credentials.
Frequently asked questions
Does Tennessee require a USDOT number for intrastate trucking?
- The state's published guidance lists a USDOT number only for interstate carriers, so an intrastate-only Tennessee carrier is not under a blanket state USDOT mandate. Crossing a state line for commerce triggers the federal requirement on its own, and the state's own credentials still apply in-state.
Does Tennessee issue its own carrier number?
- No. Tennessee issues no separate state carrier number. The fact rows on this page show which credential the state uses instead and which agency administers it, with the official source beside each fact.
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.
