How to Get a USDOT Number (2026 Step-by-Step)
How do I get a USDOT number?
Apply on the FMCSA Unified Registration System using form MCSA-1. There is no filing fee, and the number is usually issued the same session. You need your legal business name, EIN, business address, vehicle count, cargo classification and a Login.gov account. Interstate for-hire carriers then apply for MC operating authority separately.

Who has to file this
- Any carrier operating a vehicle over 10,001 lbs GVWR in interstate commerce
- Carriers hauling hazardous materials in quantities requiring placards
- Carriers transporting 9 or more passengers for compensation
- Many intrastate carriers — over 30 states require a USDOT number for intrastate operation
How to file it, in order
- 1
Create a Login.gov account
FMCSA registration runs through Login.gov. Use a business email you will keep — every future filing and biennial update goes through this account.
- 2
Get your EIN from the IRS
Free, online, issued instantly. FMCSA will not accept a Social Security number for a company registration.
- 3
Complete form MCSA-1
Legal name, DBA, physical address (no PO box), company officials, vehicle count, driver count, cargo classification and operation type.
- 4
Pick your operation classification carefully
Interstate vs intrastate, for-hire vs private. This drives which further filings apply to you and is a pain to correct later.
- 5
Record the number and file your biennial update
A USDOT number must be updated every two years even if nothing changed, or FMCSA deactivates it.
What trips new carriers up
- Using a residential PO box as the principal place of business — FMCSA requires a physical street address.
- Registering as intrastate to save a step, then crossing a state line under the wrong authority.
- Skipping the biennial update, which deactivates the number and can shut down the operation.
Questions new carriers ask
How much does a USDOT number cost?
Nothing. FMCSA charges no fee for a USDOT number. Any service charging you hundreds of dollars for one is charging for form-filling, not for the number itself.
How long does a USDOT number take?
Most applications are issued in the same session once the MCSA-1 is submitted. Applications flagged for review can take a few business days.
Do I need a USDOT number and an MC number?
If you haul regulated commodities for hire across state lines, you need both. The USDOT number identifies the carrier; the MC number is the operating authority that lets you haul for compensation.
Do I need an ELD as soon as my USDOT number is issued?
You need an FMCSA-registered ELD from the first mile you operate a covered vehicle, not from the date the number issues. Most new carriers register their ELD while the authority is still pending so nothing blocks the first load.
