Free MC number lookup — paste an MC, MX, or FF docket

Last updated: 2026-10-07

An MC number lookup returns the motor-carrier docket on one page: legal name, linked USDOT, census telephone, flags, and fleet. Paste the MC, MX, or FF from the rate con; this is the free first look before you finish authority and insurance on Licensing & Insurance.

An MC is not a USDOT number. If the thread says DOT, use DOT lookup — the same digits can be a valid USDOT for one company and an MC for another.

MC is not a USDOT number — search MC numbers accurately

A rate confirmation that says “MC 1515” is a docket. A confirmation that says “DOT 44110” is a census identity. When you need to search MC numbers or run a motor carrier number lookup, use this tool for dockets. Use DOT lookup for USDOT numbers and safety inspection data.

Need to compare how both numbers work together? Read our broker guide to MC number vs DOT number.

Bare digits in an email are ambiguous. Prefix MC when it is a docket. If you guess wrong, you will pull a different company’s record. Do not book from a guess.

When the thread only gives a company name, use carrier name search to identify candidate USDOT and MC numbers, then verify the exact record on DOT lookup and this tool.

what this report shows

Legal name and DBA (if listed) tied to the docket you entered
USDOT linked to that authority record when FMCSA lists one
Census telephone and physical address on the linked USDOT when available
Flags and fleet counts from the census snapshot on that company

Resolving a docket to a name is the first look: legal name, USDOT, phone, flags, and fleet on one page.

what a docket grant is

For-hire interstate transportation of property usually needs an MC docket with Active common or contract authority. MX is a Mexico-domiciled docket. FF is freight forwarder. Neither is a substitute for U.S. motor-carrier property authority on an ordinary interstate van load unless that is actually the operation you are booking.

Broker of property is a different grant. A company can hold both. If the only Active line is Broker, they are not the hauler on your rate con.

one company, both numbers

The MC on the rate confirmation and the USDOT in the email must belong to the same legal name. If they do not, you are looking at two entities. Do not stitch them. Cover only after one legal name owns both identifiers.

desk sequence (docket on the rate con)

Run the MC, MX, or FF docket here. Copy legal name, USDOT, and census phone.
Match legal name (or listed DBA), DOT, and MC on the rate confirmation — including Inc vs LLC.
Call the census telephone, not the cell in the email signature.
Save dated screens with the load file.

Stop when a step fails. An Active BMC-91 does not repair a broker-only docket.

common mix-ups

Pasting MC digits into DOT lookup — Use this page for dockets; use DOT lookup for USDOT.
Treating “found” as Active authority — A resolved docket still needs an Active property line for your lane.
Booking because the MC matches but the legal name does not — Entity type and punctuation matter. Inc and LLC are different persons.
Using MX or FF when you booked a U.S. van linehaul — Read the grant type; do not assume every docket is motor-carrier property authority.

worked desk: MC resolves, broker-only authority

Thread: “MC 987654, pick up Dallas 08:00.” Lookup shows North Star Freight LLC, USDOT on the record, landline in Texas.

The authority line is Active Broker of Property — no Active common or contract motor-carrier line for property.

They may arrange transportation. They are not the motor carrier on your rate confirmation unless your contract says otherwise. Do not send a rate con naming them as the hauler. Get the actual carrier’s DOT and MC or stop.

fail closed

Do not cover when:

Docket not found after you verified prefix and digits — do not guess.
Legal name or entity type does not match the rate confirmation or W-9.
Property motor-carrier authority is not Active on this lane.
Only broker or freight-forwarder authority is Active for the role you are booking.
BOC-3 missing or rejected.
Required BI&PD filing missing, or cancellation effective before pickup.
Census phone reaches a different company or nobody who will state the DOT and MC.

what this tool is not

Not proof of cargo insurance. Not a safety rating. Not SMS percentiles. Not confirmation the email sender works for that legal entity.

common questions

How do I search MC numbers to verify a motor carrier?

Enter the 6-to-8 digit MC docket number from your rate confirmation into the search box. MC number lookup resolves the operating authority docket directly to the motor carrier’s registered legal name, DBA, USDOT number, physical terminal address, and contact information.

What is an MC number lookup versus a USDOT number lookup?

An MC number lookup resolves a for-hire operating-authority docket to the company that holds it. A USDOT lookup is the census identity. When you search MC numbers, you are checking who owns the grant; use DOT lookup when you have the USDOT.

What is a motor carrier number lookup used for on a broker desk?

Brokers run a motor carrier number lookup to confirm that the MC docket on a rate confirmation links to the exact legal name, USDOT, and phone number on the carrier’s W-9 before they send a rate con.

Can a motor carrier number lookup confirm active insurance?

A lookup shows whether an MC docket resolves and gives census context: legal name, USDOT, phone, flags, and fleet. Sign in to monitor that carrier after you approve.

Can a company have Active broker authority but not motor-carrier authority?

Yes. Broker of property is a distinct grant. If the only Active line is broker (or freight forwarder), they are not authorized to operate as the motor carrier hauling your freight.

MC not found when I search MC numbers — what should a broker do?

Verify the prefix (MC, MX, or FF) and check for typographical errors. If the docket was granted very recently, records may lag. Never book a carrier from a load-board badge alone when their docket cannot be resolved.
