How to look up a USDOT number

Choose the identifier you actually have

Enter a USDOT number in lookup. If your paperwork gives an MC, FF or MX docket, preserve its prefix and use docket lookup. Do not relabel an MC number as USDOT because both contain digits.

With only a name, search the legal name or DBA and narrow by state if you know it. More than one business can have a similar name.

Reconcile the result

Compare the returned USDOT, legal name and location with your paperwork. A DBA may explain a trading name, but it does not by itself resolve a mismatch. Open the official source when the identifiers disagree.

• Keep the identifier in your notes so a later name change does not break the reference.
• Read registration and operating authority separately.
• Record the retrieval time alongside the fields you use.

Handle a missing result without inventing a conclusion

Check the identifier type and spelling first. Baseline’s directory is a limited snapshot, while source requests may be unavailable. A missing result is not proof that the entity is unregistered or fraudulent. Use the official Company Snapshot to continue the search.

Make the next check specific

A matching record answers “which entity is this?” It does not establish that the person offering a load represents that entity. For that question, use an independently established contact route and document the response.
