What an MC Number and DOT Number Actually Are
A DOT number identifies a company registered with the U.S. Department of Transportation for safety oversight. An MC number (Motor Carrier number) identifies its specific operating authority—whether it’s licensed to broker freight, physically carry freight, or both. A company can hold a DOT number without active MC authority, which matters, because DOT registration alone doesn’t confirm the company is legally allowed to move a customer’s vehicle right now.
Where to Look: FMCSA's SAFER System
The FMCSA maintains a free public lookup tool called SAFER (Safety and Fitness Electronic Records), accessible at safer.fmcsa.dot.gov. Searching a company’s name, DOT number, or MC number returns a “Company Snapshot” showing operating status, authority type, insurance filings, and safety history. No account or payment is required, and any company that discourages a customer from checking this record on their own is worth reconsidering.
Step 1: Get the Company's DOT or MC Number
A legitimate company will provide its DOT and MC numbers on request, and reputable ones list them directly on their website or in a quote email. If a company hesitates, deflects, or claims the numbers aren’t necessary, that response alone is a signal to look elsewhere before sharing any personal or vehicle information.
Step 2: Run the Company Snapshot Search
On SAFER, select the Company Snapshot search, enter the DOT or MC number, and pull up the record. The snapshot header shows the legal business name, entity type, and whether the company is authorized as a broker, a carrier, or both—confirming or contradicting what the company told the customer directly.
Step 3: Check Operating Status
The record will show operating status as “Active,” “Not Authorized,” “Revoked,” or similar. Only “Active” status means the company is currently permitted to operate under that authority. A company operating with revoked or inactive authority may still take bookings and deposits—the record is the only way to know it shouldn’t.
Step 4: Confirm Insurance Is On File
The snapshot lists whether liability and cargo insurance are on file and current. For a carrier, cargo insurance on file is what would actually cover a vehicle in the event of damage during transport. If insurance shows as expired, missing, or “None,” that carrier has no verified coverage backing the shipment regardless of what a salesperson claims over the phone.
Step 5: Review Safety and Inspection History
Further down the snapshot, SAFER shows crash history, inspection counts, and out-of-service rates compared to national averages. A single flag isn’t automatically disqualifying—every carrier accumulates some inspection history—but an out-of-service rate significantly above the national average across multiple categories is worth treating as a pattern, not an outlier.
Matching the Business Name to the Company Someone Is Actually Talking To
Some operators quote under one name and dispatch or invoice under another. If the legal name on the SAFER record doesn’t reasonably match the company name, website, or the name on a quote, ask directly why. Reused authority under a different public-facing brand is a known tactic among companies that have had authority issues under a previous name.
What a Broker's Record Should Show Versus a Carrier's
A broker’s SAFER record will typically show broker authority and a broker’s own liability insurance—not cargo insurance, since a broker doesn’t physically transport the vehicle. That’s expected and normal. What matters is that once a carrier is assigned, that carrier’s own DOT and MC numbers can also be checked, with its own active status and cargo insurance confirmed separately from the broker’s.
Red Flags Worth Stopping On
No DOT or MC number provided on request. A snapshot showing “Not Authorized” or “Revoked” status. No insurance on file. A legal business name that doesn’t match the company’s public identity. Pressure to book or pay a deposit before these checks are completed. Any one of these is reason enough to keep comparing options rather than proceed.
Why This Two-Minute Check Matters More Than Reviews
Online reviews can be manufactured or removed selectively. FMCSA operating status and insurance data cannot be edited by the company itself—it’s federal record, updated through the same regulatory process every licensed operator goes through. Treating the SAFER lookup as the first check, before reviews or price, filters out the companies that shouldn’t be in consideration at all.
