USDOT number check: four free tools compared

A USDOT number check takes under a minute, and the tool you use decides what you learn. Some show the company's status. Some show insurance. One shows a safety record. None shows everything. This review compares four free ways to check a number: two long-standing FMCSA tools, the raw open data, and ours. Haul10 built one of them, so we have tried to say plainly where it falls short. Pick by what question you need answered.

What are you trying to find out?

It helps to split the job in three, because each tool is strongest at a different one.

• Is this number active? A basic yes or no on status.
• Does the carrier have authority and insurance? The question brokers care about most.
• What is its record? Inspections and crashes.

The data under all four comes from FMCSA. Its own description of the census file is plain enough:

The Company Census File contains records for active, inactive, and pending entities registered with FMCSA.

The four tools at a glance

1. The SAFER company snapshot

This is the old workhorse. Type a USDOT or MC number and you get a one-page profile: legal name, status, operating authority, power units, drivers, mileage and a summary of inspections and crashes.

Good for: a quick view of who a carrier is, and its safety numbers. Falls short: it does not show insurance details, and it is a page you read, not data you can drop into a spreadsheet. Check FMCSA's site for how it is changing now that registration has moved to Motus.

2. Licensing and Insurance

This is the tool for the motor carrier insurance check. It lists operating authority, the insurance filed against it, the insurer, the effective dates and any cancellation. Brokers use it daily.

Good for: confirming that liability insurance is on file and when it started. Falls short: it does not give a fleet size or a safety record, and its search forms are fiddly on a phone.

3. The raw open data

FMCSA publishes two datasets on data.transportation.gov that anyone can query without a key. The Company Census File holds name, status, power units and the date of the last MCS-150. The Motus Carrier dataset holds the status of operating authority and the liability insurance on file.

Good for: developers, brokers with a system, and anyone checking many numbers at once. Falls short: it is raw. You need to know the field names, and a number with no match tells you little.

4. Haul10's check

We built the check on those two datasets. You type a USDOT number and see the carrier name, active or inactive status, whether operating authority and liability insurance are active, the MCS-150 due date and last update, and the UCR bracket and fee for the year. It shows the date of the data it read. If FMCSA's service does not answer, it says so, and may serve the last good answer, dated.

Good for: owners who want status and due dates in one view. Falls short: no safety record, no insurer name, and nothing on BOC-3, IRP or Form 2290, because open data does not hold them. It is a summary, not a vetting report.

How do I check if a USDOT number is active?

The fastest route is the status line in any of the four tools. If the number is inactive, the common cause is a missed biennial update. Our guide to a deactivated USDOT number explains the way back. And note that FMCSA has paused deactivation for updates due from 1 June 2026, so a number that is active today may be overdue anyway; see our news post on the pause.

How do I check a carrier's insurance?

For a proper motor carrier insurance check, use Licensing and Insurance. It shows the filing, the insurer and the dates. For a first-pass yes or no, the Haul10 check and the open data both show whether liability insurance is on file. Neither replaces asking for a certificate before you book a load.

A broker's afternoon

Picture a small broker, Whitlow Freight, vetting a new carrier for a Friday load. The dispatcher has 20 minutes. She starts with the open-data view of the number: active, authority active, insurance on file. Good. Then she opens Licensing and Insurance to read the insurer and the start date, because the load is high value. Last, she opens the SAFER snapshot for inspections. Three tools, ten minutes, and each answered a different question.

That is the realistic pattern. The tools are not rivals. They stack.

Which one should you pick?

If you are an owner checking your own number, start with the first row. Then read the MCS-150 biennial update deep dive if the last-update date looks old. For the biggest stakes, use all three.

Common mistakes in a USDOT number check

A USDOT number check is only as good as the question you ask. These are the slips we see.

• Mixing up numbers. A USDOT number and an MC number are not the same thing. Make sure the tool you use is looking up the one you typed.
• Trusting "active" too far. Active means the number is live. It does not prove insurance is current or that the carrier is the one you think.
• Ignoring the date. Every USDOT number check shows data as of some date. If you cannot see it, ask.
• Stopping at one tool. For a load of any value, use two.

Using a USDOT number check in carrier onboarding

If you run a brokerage or a dispatch desk, a repeatable routine saves arguments. A simple three-step version:

1. Run the USDOT number check for status and authority.
2. Open Licensing and Insurance for the insurer and dates.
3. Ask the carrier for a certificate of insurance and compare.

Write down the date and the result each time. A note that says "checked 4 November, active, insured" is worth more than a vague memory.
