Look up a numberHow to look up whether you already have a USDOT number
The easiest duplicate to fix is the one you never create. A few minutes of searching before you apply can save weeks of untangling later.
This site is not affiliated with FMCSA, the U.S. Department of Transportation, Login.gov, or any government agency. You can contact FMCSA directly and file yourself. Help from this site is optional and paid.

Consult with a Compliance SpecialistUse the free public snapshot
The SAFER Company Snapshot is FMCSA's public lookup. Search by USDOT number if you have one, and also by legal name and by DBA name. Name searches can miss a record if the name was entered differently, so try a few spellings and the owner's name if the business ever ran as a sole proprietorship.
Why this takes time: it takes several searches by number, legal name, DBA and owner name, because records can be entered under different spellings.
What the status on SAFER is telling you
SAFER's help page defines its operating status labels. In its words:
- ACTIVE: "The entity's US DOT number is active."
- NOT AUTHORIZED: the USDOT number is active, but the carrier does not have operating authority to operate as an interstate, for-hire carrier. SAFER notes this does not apply to private or intrastate operations.
- Inactive USDOT Number: SAFER describes this as a biennial update of MCS-150 data not completed.
- OUT-OF-SERVICE: the carrier is under an out-of-service order and is not authorized to operate.
An inactive number is still your company's number. FMCSA's reactivation FAQ describes reactivating it with the MCS-150 series form, and FMCSA's Motus page lists reactivation as a Motus action. Applying for a new number instead is how many duplicates start.
Why this takes time: each status label points to a different next step, such as reactivating, updating or adding authority.

Consult with a Compliance SpecialistAlso check Motus if you can sign in
FMCSA's Move into Motus page lists a public search of registration records in Motus. If your company already has a number, FMCSA's claim job aid explains that the company's authorized person can claim that existing record in Motus instead of registering again.
Why this takes time: signing in to Motus requires Login.gov and identity verification first.
If you find one number, do not apply for another
Claim, update or reactivate the number you found. See can you have two DOT numbers. If you find two, see what to do if you applied twice.
Why this takes time: claiming, updating and reactivating each have their own steps and forms.
That is a lot of forms and logins for one fix. Hand it to a compliance specialist.
Consult with a Compliance SpecialistIf you find nothing
Only then is a new application the right step, and even then a similar name or an old sole-proprietor record may be hiding. If you do need a first number, howtogetadotnumber.com covers the application, and dotnumberapplication.com lists common USDOT application mistakes to avoid.
Recurring deadline: FMCSA requires an MCS-150 update every 24 months, on a schedule set by the last two digits of the USDOT number, even if nothing changed. Each active number has its own schedule. FMCSA says a missed update will result in deactivation of the USDOT number and may result in civil penalties of up to $1,000 per day, not to exceed $10,000 (source). FMCSA's Resources Hub has noted a temporary pause on inactivations for missed biennial updates, so check it for the current status.
Common questions
Where can I look up a USDOT number for free?
FMCSA's SAFER Company Snapshot is the public lookup, at safer.fmcsa.dot.gov.
SAFER shows my old number as inactive. Can I get a new one?
Do not apply for a new one just because the old one is inactive. FMCSA's form instructions say a company that has or has had a number should not apply again, and FMCSA describes reactivation as the path.
Why don't I see my company under the name I use now?
The public record may still list the legal name or an older DBA. Search variations, and remember a number may exist under a sole proprietor's own name.
Is Motus search the same as SAFER?
FMCSA lists a public search of registration records in Motus as well as SAFER. Use both if you are unsure.
Can someone else look up my number?
Yes. SAFER is public.
