MC Number Search

An MC docket isn't one thing — it's a container for authority grants, and what each grant permits is the whole game in vetting. This guide covers the authority types, when to search an MC versus a DOT, how to verify a broker's bond, and where docket numbers are headed as FMCSA modernizes registration.

Authority types: what each grant actually permits

When FMCSA licenses an entity for interstate for-hire commerce, it opens a docket — the familiar MC-XXXXXX (or FF-XXXXXX / MX-XXXXXX) — and attaches one or more grants of authority to it. The docket number is just the filing cabinet. The grants inside determine what the business may lawfully do:

Motor carrier of property

Permits hauling regulated freight for compensation across state lines. This is the grant behind virtually every truckload and LTL carrier you'll tender to. Requires a BMC-91/BMC-91X public liability filing to activate and stay in force. Older dockets may still carry the historical "common" or "contract" carrier labels; MAP-21 collapsed that distinction into a single unified property authority, so the label itself no longer changes what the carrier may do.

Motor carrier of household goods

A distinct grant covering personal/household moving services, with its own consumer-protection obligations (written estimates, arbitration programs). A general freight carrier without the HHG grant cannot legally run interstate household moves — a detail that matters constantly in the moving-scam economy.

Motor passenger carrier

Covers for-hire interstate transport of people — charter buses, shuttle operators. Higher insurance minimums apply ($1.5M–$5M depending on seating capacity, versus $750K baseline for general freight).

Broker of property (and broker of HHG)

Permits arranging transportation performed by others — no trucks required or implied. Financial security is a $75,000 bond or trust, not liability insurance. If the entity in your email thread holds only broker authority, they will never touch your freight; someone else will, and you should know who.

Freight forwarder

The FF docket. Forwarders take responsibility for the shipment itself — consolidating, breaking bulk, issuing their own bill of lading — often moving goods on carriers they hire. Legally closer to a carrier than a broker, with both liability and financial-security obligations.

Mexico-domiciled carrier

The MX docket covers carriers domiciled in Mexico operating within the US under specific scope restrictions. You'll encounter these mostly in border-zone drayage.

Key vetting habit: one docket can hold several grants in different states of health. Always check the status of the specific grant that covers your transaction, not just whether "the MC is active."

MC or DOT: which number should you search?

Both identifiers resolve to the same company profile on MC Look Up, so you can't really search "wrong" here — but knowing which number answers which question makes you faster and sharper:

Situation Search this Because
Vetting a carrier's safety & inspections DOT number Inspection, crash, and safety-measurement data is keyed to the USDOT, not the docket
Confirming for-hire licensing & insurance filings MC docket Authority grants and BMC filings live in the licensing system under the docket
Vetting a freight broker MC docket Brokers have no trucks — the bond and broker grant are the entire record
Number painted on the truck door DOT number Vehicle marking regulations require the USDOT on equipment; the docket is optional
Old paperwork showing only MC-XXXXXX MC docket We resolve it to the current USDOT and full profile automatically
Private fleet (hauls its own goods) DOT number Private carriage needs no operating authority — there may be no docket at all

Rule of thumb: the DOT tells you how they run; the MC tells you what they're licensed to do. Full verification reads both, which is why our profiles merge them into one view. For the safety-side reading order, see the DOT number check workflow.

Vetting a broker's MC: the bond is the story

Carriers get vetted on safety; brokers get vetted on money. A broker holds your receivable, not your freight — so the questions shift from inspections to solvency and the instrument that backs payment:

1

Confirm the broker grant is currently authorized

Not the carrier grant, not "the MC" generically — the broker-of-property line specifically. Revoked broker authority with active carrier authority (or vice versa) is a configuration scammers exploit.

2

Verify the $75,000 financial security

Every broker and freight forwarder must keep a BMC-84 surety bond or BMC-85 trust fund on file. No active instrument, no authority — FMCSA revokes within 30 days of a lapse notice.

3

Note which instrument and who issued it

BMC-84: a surety underwrites the broker and adjudicates claims. BMC-85: assets parked with a trustee. Sureties add a layer of vetting discipline; loosely administered trusts have featured in some of the industry's messier broker collapses.

4

Read the filing history for churn

A bond replaced every few months, or gaps between cancellation and re-filing, signals a broker sureties keep dropping. Pair that with authority age — a weeks-old broker MC cold-calling carriers with above-market rates is the standard double-brokering setup.

Watch the dual-authority angle. Entities holding both carrier and broker grants can accept a load as a "carrier" and quietly re-broker it. Cross-checking who actually hauls is part of the verification checklist, and re-registration patterns get flagged by our chameleon screening.

MC number retirement and FMCSA's registration modernization

The docket-number system predates FMCSA itself — it's inherited from the Interstate Commerce Commission era. FMCSA has been working for years to consolidate registration into a single modern system in which the USDOT number serves as the sole identifier for every registered entity, with authority details recorded as attributes of that number rather than as separate MC/FF/MX dockets.

What this means in practice for anyone vetting carriers:

  • Nothing changes about existing dockets yet. MC numbers on file remain valid, searchable, and legally meaningful until the transition completes. The timeline has slipped repeatedly, so plan on a long coexistence period.
  • Key your internal records to the USDOT. It's permanent, universal (every entity has one; not every entity has a docket), and it's where safety data already lives. Store the MC as a secondary attribute.
  • Expect newer entities to lead with their DOT. As FMCSA's onboarding shifts, paperwork that shows only a USDOT number is increasingly normal and not by itself suspicious.
  • Fraud patterns will follow the transition. Any identifier migration creates confusion, and confusion is raw material for scams. Verifying against the live federal record — rather than numbers printed on documents — matters more, not less.

MC Look Up already treats the USDOT as the primary key and the docket as an attribute, so searches keep working regardless of which identifier you start from — today and after the changeover. You can also browse licensed carriers by geography in the carrier directory.

Frequently asked questions

Can one company hold carrier and broker authority at the same time?

Yes — a single docket can carry motor carrier, broker, and freight forwarder grants simultaneously, and plenty of legitimate businesses run that way. The vetting implication: confirm which grant covers your transaction. Capacity quoted under broker authority means someone else's truck moves the load, and your recourse runs through the bond rather than the carrier's insurance.

Is the MC number going away?

That's the plan of record. FMCSA's modernization program aims to make the USDOT number the single identifier, retiring separate dockets for new registrants once the replacement registration system is fully live. The schedule has slipped more than once, existing dockets stay valid throughout, and both identifiers work in our search — so record both and key your files to the DOT.

What bond does a freight broker need?

$75,000 in financial security, mandated by MAP-21 since October 2013 — up from the long-standing $10,000. It's satisfied by either a BMC-84 surety bond or a BMC-85 trust fund. Carriers stiffed by the broker file claims against that instrument, which is also why a $75K fund can evaporate fast in a large collapse: it's a ceiling, not a guarantee of full recovery.

BMC-84 versus BMC-85 — does it matter which one a broker has?

Functionally both satisfy the requirement. Practically, a BMC-84 means a surety company underwrote the broker's financials and will adjudicate claims; a BMC-85 means assets sit with a trustee, and the quality of administration varies. Neither is disqualifying, but a brand-new broker on a loosely administered trust warrants tighter credit terms.

What does "reinstated" mean on an authority record?

The grant was revoked — usually because an insurance or bond filing lapsed — then restored after the filing was cured and the reinstatement processed. A single old lapse is common and forgivable. A record that cycles revoke→reinstate every year or two describes a business that habitually runs at the edge of losing its coverage; our scoring counts that churn against the carrier.

A company has a DOT number but no MC docket — is that a problem?

Only if they're trying to haul your regulated freight for pay across state lines — that requires property authority, full stop. But registration without any docket is completely normal for private fleets and exempt-commodity haulers (certain unprocessed agricultural products, for example). Context decides; the DOT check workflow shows how to read the entity type field that settles it.
