Question 1

How do I run a free MC number lookup?

Accepted Answer

Enter MC followed by the docket number, such as MC-133655, in the search above. Keep the MC prefix: a number entered on its own is searched as a USDOT number. Review the returned legal name and USDOT, then follow the official SAFER link to verify the record. No account is required.

Question 2

Does a missing result mean the carrier has no authority?

Accepted Answer

No. Check the identifier and try the carrier's USDOT number or company name. A missing result or an unavailable public source does not establish the carrier's operating status. Verify the record directly with FMCSA/SAFER before booking.

Question 3

How do I look up a carrier's USDOT or MC number?

Accepted Answer

Enter the USDOT number, MC/docket number, or company name. CarrierSentry queries public FMCSA records and shows carrier identity, operating status, safety rating, out-of-service data and available insurance-filing fields.

Question 4

Is the carrier lookup free?

Accepted Answer

Yes. The carrier lookup is free and does not require an account. Public records can be delayed, so verify the result with FMCSA/SAFER before tendering a load.

Question 5

Is there an affordable carrier monitoring option for a small broker?

Accepted Answer

Yes. Starter is $19 per month for up to 25 selected carriers, and Pro is $49 per month for up to 100. Both add a daily FMCSA re-check and email when a monitored field change is detected.

Question 6

What should I check before booking a carrier?

Accepted Answer

Confirm the legal name, DBA, USDOT and docket number; review operating status, available insurance-filing fields, safety rating and out-of-service data; then complete your existing identity, contact, banking and onboarding checks.

Question 7

What does monitoring alert me to?

Accepted Answer

CarrierSentry re-checks selected FMCSA fields daily and emails you when it detects a change in a monitored authority, reported insurance-filing status or safety-rating field. It is not a real-time alert service.

Question 8

Does CarrierSentry replace Carrier411, Highway or my TMS?

Accepted Answer

No. CarrierSentry complements FMCSA/SAFER, commercial vetting tools and your TMS. It does not replace carrier onboarding, identity verification, insurance confirmation or dispatch controls.

Question 9

Where does the data come from?

Accepted Answer

Data comes from public FMCSA records. CarrierSentry is an independent service and is not affiliated with the U.S. DOT or FMCSA. Each real carrier result links to the official SAFER snapshot.
