How to spot a hijacked MC number before you book a load

Updated 2026-10-10. Every outside fact links its source.

A hijacked MC is a real carrier's authority being used by someone who isn't that carrier. On paper it looks clean: active authority, insurance on file, years of history. FMCSA describes this as fraud and identity theft: an entity using another motor carrier's USDOT number without authorization. In FMCSA's words, "Fraud and identity theft are criminal acts" (FMCSA: Broker and Carrier Fraud and Identity Theft).

Because the authority itself is genuine, a one-time lookup often passes. The checks below are about the gap between who the record says the carrier is and who is actually on the phone with you.

1. Call the number on the FMCSA record, not the number you were given

FMCSA's advice is to confirm phone numbers using SAFER, and if the number you were given does not match the posted one, to call the number posted in SAFER (FMCSA).

Call rather than email: if the carrier's real email account has been taken over, a "confirmation" by email proves nothing. If SAFER shows no phone number at all, FMCSA suggests you "consider not contracting for the work until you can confirm it is a valid transaction" (FMCSA).

2. Notice when the record itself changed recently

A hijack doesn't always leave the record alone. Sometimes the phone or email on the FMCSA record is changed so that verification calls reach the thief. A record that matches the person you're talking to isn't enough if it was changed last week.

Two practical habits:

• Save the SAFER phone and email when you first onboard a carrier, and compare them each time you book.
• Treat a recent contact change on an established carrier as a reason to verify through a second channel, such as a number from an older paperwork packet or the carrier's insurance agent.

3. Check "Active" for what's about to change

SAFER shows today's status. It doesn't warn you that a status is about to flip. FMCSA serves involuntary suspension notices with a future effective date, so a carrier can show "Active" while a suspension is already scheduled.

These notices are common: FMCSA's public file (dataset wb4f-neki) lists thousands of them a month. Our notices page shows every one served in the last 14 days, copied from that file, and the free list check shows whether any of your carriers has one.

4. Don't rely on a single source, or on a stale one

FMCSA advises: "Do not trust the information unless you can confirm it on multiple sites." It also warns that "even insurance certificates can be fraudulent", so get the certificate of insurance from the insurer, not from the caller (FMCSA).

One more thing to know in 2026: FMCSA is moving licensing data to its new Motus system, and its older licensing files have stopped updating. The description of FMCSA's "Carrier - All With History" file says it "was last refreshed on 05/14/2026 and will no longer be updated" (dataset 6eyk-hxee). If a tool you use reads only those older files, its authority and insurance data may be months old.

5. Check the truck, not just the paperwork

FMCSA says having your customer record the tractor and trailer plate information helps identify the actual carrier, and suggests requesting pictures of the truck and trailer to compare against the carrier packet (FMCSA). A clean authority attached to equipment nobody can show you is a warning sign.

If it happens to you

FMCSA lists these places to report fraud and identity theft (FMCSA):

• FMCSA Contact Center or 1-800-832-5660
• FMCSA National Consumer Complaint Database
• USDOT Office of Inspector General hotline, (800) 424-9071
• Federal Trade Commission
• FBI Internet Crime Complaint Center
• Your local police and state attorney general

FMCSA also notes that the carrier whose identity was used may itself be a victim, not knowingly involved (FMCSA).

Where Carrier Ledger fits, and where it doesn't

Carrier Ledger re-reads FMCSA's records for the carriers you watch every day, after FMCSA publishes. The first check records how each record looks today; after that it alerts you when the phone or email changes, when an insurance cancellation is filed or the insurance on file changes, when authority status changes, or when a suspension notice is served. Each alert links to the carrier's page, where every fact names the FMCSA dataset and field it came from, and the change history stays there, so "the phone changed three days ago" is visible. That covers checks 2 and 3 above.

What it does not catch:

• A thief who uses a real MC without changing the FMCSA record, for example by spoofing an email address or using a look-alike domain. Check 1, calling the posted number, is your defense there.
• Who is actually driving or what equipment shows up (check 5).
• Anything outside US FMCSA records.

It is a monitoring aid, not a vetting decision.
