How to look up an MC number and read the FMCSA record

A carrier has emailed you about your load. The signature says "MC 1234567". Before you send a rate confirmation you want to know three things: does that MC number exist, does it belong to the company in the signature, and is that company allowed to haul your freight today. All three answers are in FMCSA's public record, and looking them up costs nothing. This guide shows where to look and what each line of the record means.

Where to look up an MC number for free

FMCSA, the Federal Motor Carrier Safety Administration, keeps two public systems that matter here. They hold different parts of the record, which is why a careful check uses both.

1. SAFER Company Snapshot (safer.fmcsa.dot.gov). Search by USDOT number, by MC or MX number, or by name. It shows the legal name and DBA, the physical address, the operating status, the size of the fleet from the carrier's last MCS-150 filing, inspections and crashes over the last 24 months, and the safety rating if one was ever assigned. The snapshot is refreshed on FMCSA's schedule, so a change made yesterday may not be in it yet.
2. Licensing and Insurance, usually called L&I (li-public.fmcsa.dot.gov). This is where operating authority lives: the status of each authority the carrier holds, the history of grants and revocations, the insurance filings on record with the insurer's name and amount, any pending cancellation, and the BOC-3 process agent. If your question is "can they legally haul this and are they insured", the answer is here, not in SAFER.
3. The HauLens carrier lookup (haulens.ai/carrier-lookup). One page that pulls the same FMCSA open data into the order a broker reads it, with the national averages next to the carrier's numbers and a plain reading of anything unusual. Free, no account. The record for Landstar Ranger is a good example of what a complete one looks like.

Paid vetting services such as Highway, Carrier Assure and MyCarrierPortal add identity checks, onboarding paperwork and monitoring on top of the FMCSA record. They are worth having when you onboard a carrier. They are not needed to answer the first question, which is whether the record supports what the email claims.

What to type

An MC number is the digits after "MC", "MC-" or "MC#". Six or seven digits is normal today; older carriers have fewer. Leading zeros do not matter: MC 0123456 and MC 123456 are the same docket. If the signature only gives a USDOT number, search by that instead; it is the primary key of the whole record, and every carrier with an MC number also has a USDOT number. The two are explained in MC number vs USDOT number.

If a search by MC number returns nothing, do not assume a typo and move on. Search the company name. A carrier that gives you an MC number FMCSA does not know, or one that resolves to a different company, has already answered your question.

Reading the record, in the order that matters

1. The name

The legal name and the DBA in the record must match the company in the email, the rate confirmation and the insurance certificate. "Pine Hollow Haulers LLC" and "Pine Hollow Logistics" are two different companies until proven otherwise. Then look at the physical address and ask whether it fits the story: a carrier that says it is based in Chicago with a record showing a residential address in another state deserves a phone call.

2. Operating authority

Authority is the federal permission to haul for hire across state lines. The record shows one line per authority type. For a truckload carrier you want Motor Carrier of Property reading Active. The other statuses:

• Pending: applied for, not granted. The carrier cannot haul for hire yet.
• Inactive or Revoked: the authority was taken away or given up, usually because insurance lapsed. No hauling.
• Broker authority is not carrier authority. A company with only broker authority that offers to haul your load will be handing it to someone else.

Then read the date. "Authority on record since" tells you how long the company has held it. New authority is not a crime, and every good carrier was new once. But authority under a year old is the profile fraud rings prefer, because the record is thin and nobody has history with the company. Treat it as a reason to call the number FMCSA has on file, not the number in the email.

3. Insurance filings

Federal law requires a for-hire carrier to keep proof of liability insurance on file with FMCSA before authority is granted and for as long as it is held. On the record this appears as a filing with a form code, an insurer, an amount and an effective date.

• BMC-91 or BMC-91X is liability, called BIPD (bodily injury and property damage). General freight in vehicles over 10,001 pounds needs at least $750,000. Oil and certain hazardous materials need $1,000,000; the most dangerous hazmat classes need $5,000,000.
• BMC-34 is cargo insurance. FMCSA requires it only from household goods carriers and freight forwarders. For general freight it is optional, so a carrier with no cargo filing is not doing anything wrong, and a carrier with one is not necessarily covering your load. Ask the carrier's insurance agent for the certificate.
• BMC-84 and BMC-85 are the $75,000 broker bond or trust fund. On a carrier's record they mean the company also brokers.

Check the insurer's name against the certificate you are sent. A certificate naming an insurer that is not the one on file with FMCSA is the oldest trick in the book. And look for a pending cancellation: the insurer has told FMCSA the policy ends on a stated date. The full checklist is in how to check a carrier's authority and insurance.

4. Safety

Most carriers have no safety rating, because FMCSA only assigns one after a compliance review and most carriers never get one. "Not rated" is normal. Conditional means a review found problems; Unsatisfactory means the carrier is not allowed to operate.

The numbers that are always there are the roadside inspection results over the last 24 months. Two rates matter: the share of vehicle inspections that put the truck out of service, and the share of driver inspections that put the driver out of service. Compare them with the national averages, which sit around 22 percent for vehicles and 7 percent for drivers in FMCSA's data. A carrier well above both, on a meaningful number of inspections, is telling you something about how it maintains trucks and manages hours. A carrier with two inspections in two years is telling you it is small, not that it is safe.

5. Fleet size

Power units and drivers come from the carrier's own MCS-150 filing, which it must update every two years. Read them against the email. A two-truck carrier offering to cover ten loads a day, or a carrier whose "dispatch" covers lanes on both coasts with three trucks, is either double brokering or overpromising. Neither is your carrier.

6. Out of service orders

An out of service order in effect means the carrier may not operate at all. It is rare on a carrier that is still emailing brokers, which is exactly why it is worth the two seconds to check.

What the record cannot tell you

The record describes a company. It says nothing about whether the person emailing you works for that company. Most double brokering and carrier identity theft starts exactly there: a real MC number with a clean record, used by someone who has no connection to the carrier. The record checks out because it is somebody else's record.

Three checks close that gap, and none of them is in FMCSA's systems:

• The email domain. Does it match the company, and how old is it? A domain registered last month for a carrier with fifteen years of authority is the tell.
• The phone number. Call the number FMCSA has on file for the carrier, not the one in the email signature, and ask whether they sent the quote.
• The rate. A carrier offering to run your lane well under market is often not planning to run it at all.

Doing this for every carrier email by hand takes a few minutes each. HauLens does the record and the sender check inside Gmail, beside the email, for every carrier that writes to you.

Mistakes that cost loads

• Mixing up MC and USDOT numbers. Searching an MC number in the USDOT field, or the other way round, returns nothing or the wrong carrier. Use the right field, and confirm both numbers resolve to the same legal name.
• Trusting the carrier packet. The packet comes from the sender. The record comes from FMCSA. Only one of them is evidence.
• Checking once. Insurance cancels, authority lapses, and a carrier that was fine in March may not be in July. Re-check before each load, or use something that watches for you.
• Reading a clean record as a safe booking. Clean record plus wrong sender is the standard fraud. The record is half the check.

Every figure in this guide is a federal minimum or an FMCSA field, checked against the public record when it was last updated. It is practical guidance for brokers, not legal advice.
