Every interstate trucking company has a USDOT number, and its record is public. A USDOT number lookup lets you check any carrier, including your own, in under a minute. Brokers do it before every load, and insurers do it before every quote.
🔎 How to Look Up a USDOT Number
- Go to safersys.org (FMCSA SAFER) and choose Company Snapshot.
- Search by USDOT number, MC number or company name.
- Open the snapshot to see the record.
Faster option: our free FMCSA check shows the operating status, MCS-150 date and the insurance on file in one place. For a full walkthrough of the snapshot, see our FMCSA SAFER guide.
📋 What Each Status Means
- Active: the USDOT number is current.
- Inactive: usually the MCS-150 update was missed. File it to reactivate.
- Authorized for Property: the company has active MC authority to haul for hire across state lines.
- Not Authorized: no active authority, often because the insurance filing or BOC-3 is missing or was cancelled.
- Out of Service: FMCSA has ordered the company off the road. It cannot legally operate until the order is lifted.
The snapshot also shows the safety rating and inspection and crash counts for the last 24 months.
🔧 If Your Own Status Is Wrong
- Inactive: file your MCS-150.
- Not Authorized: make sure your insurer filed the BMC-91 and your BOC-3 is on file.
- Insurance missing: call your agent; a cancelled filing makes authority go inactive in about 30 days.

Frequently asked questions
Is a USDOT number lookup free?
Yes. SAFER at safersys.org and our FMCSA check tool are both free and need no login.
Why does my USDOT show Inactive?
Usually because the MCS-150 biennial update was not filed on time, or the company asked to deactivate. File the MCS-150 to bring it back.
Why does it say Not Authorized when I have a USDOT number?
The USDOT number and operating authority are different. Not Authorized means there is no active MC authority, often because the insurance filing (BMC-91) or BOC-3 is missing or was cancelled.
