Home / Safety history
Safety historyWhat happens to your safety history if you have two USDOT numbers?
This is the worry behind most duplicate-number questions. The honest answer: a second number can split your record, and it does not erase the first one.
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.
Rather not deal with this? Hand it to a compliance specialist.
Consult with a Compliance SpecialistWhy history matters
FMCSA's Do I Need a USDOT Number? page says the USDOT number "serves as a unique identifier when collecting and monitoring a company's safety information acquired during audits, compliance reviews, crash investigations, and inspections."
Two active numbers can split that record
If a company has two active numbers, inspections, crashes and filings can end up on different records. That is one reason SAFER's help page says each company should have only one active census number. For roadside and insurance examples, see risks.
A new number does not wipe the old record
FMCSA's guidance says a USDOT number stays assigned to the same person forever, and FMCSA's bulletin warns against handing a number to anyone else. The old record still exists and still belongs to that person.
FMCSA can act on reincarnated or affiliated carriers
Under 49 CFR 386.73, FMCSA may issue an out-of-service order, and may order records consolidated, when it determines a carrier operated or tried to operate under a new identity or as an affiliated entity to avoid things such as an FMCSA order, a civil penalty or a negative compliance history. Using a new number to get away from a record is the wrong goal.
The practical path
List every number tied to the company, keep the one that belongs to the legal entity, take the extra one out of use, and line up markings and filings with the number you keep. See how resolution generally works and how to deactivate a duplicate. No one can promise a combined score or a date when the public record will look the way you expect.
Why this takes time: each of those is a separate task, and the public record only changes after FMCSA processes each one.
That is a lot of forms and logins for one fix. Hand it to a compliance specialist.
Consult with a Compliance SpecialistCommon questions
If I start a new USDOT number, does my inspection history reset?
No. The old number and its record still exist. A second number can split the record rather than clear it.
Can FMCSA move inspections from the extra number to the one I keep?
We cannot promise that. FMCSA has rules allowing it to consolidate records in certain enforcement cases under 49 CFR 386.73, but that is an agency decision, not a routine request.
Which number will a roadside officer look up?
Whatever number is on the vehicle or comes up in the system. That is one reason your markings and the public record should match the number you keep.
Should I keep the newer number because it is clean?
No. That keeps the record split, and using a new identity to avoid a compliance history is exactly what 49 CFR 386.73 addresses.
Where do I start?
Look up every number tied to your company, then read the resolution page or request a record review.
