U.S. · FMCSA · Licensing & Insurance
Check a trucking company’s operating authority.
Where the FMCSA records who has been granted interstate for-hire authority, what the Licensing & Insurance Carrier Search asks for, and how to read what comes back. The tool tells you which field to use; the search itself runs on the FMCSA site.
Short answer: Operating authority is checked on the FMCSA Licensing & Insurance (L&I) public website, whose Carrier Search provides access to information about interstate for hire carriers who have been granted authority or who have applications pending. The search takes a USDOT Number or a Docket Number with an MC, FF or MX prefix; if you know either one, the page says that is all that needs to be entered. Otherwise you can combine a legal name, a DBA name and a state. The system is also where insurance companies and BOC-3 blanket agents file financial responsibility and process-agent documents, which is why L&I, not SAFER, is the place to confirm that a carrier’s authority and filings are in order. New applications do not appear in search results for 24 hours after filing.

What the Licensing & Insurance system is
The FMCSA keeps two public systems that get confused with each other. SAFER holds the safety record, the Company Snapshot covered on the MC number page. The Licensing & Insurance website holds the registration record: the L&I home page describes its Carrier Search as the option that provides access to information about interstate for hire carriers who have been granted authority or who have applications pending. The same site is where, since December 2024, insurance companies, financial institutions and BOC-3 blanket agents log in through Login.gov to make financial responsibility filings and Form BOC-3 submissions. So the authority, the insurance filed against it and the process-agent designation all sit in one place, and that place is L&I.

How to search
The Carrier Search page offers a USDOT Number box, a Docket Number box with a prefix list of MC, FF and MX, Legal Name and DBA Name boxes and a State list that covers U.S. states and territories, Mexican states and Canadian provinces. Its instructions are short: if you know the USDOT or docket number, that is all that needs to be entered. Name searches match names that begin with the text entered; putting the wildcard in the first position searches for names that contain the text, which the page warns will take longer, and it advises adding a state to narrow a name search. The form is a POST, so no link can prefill it; the tool above reads what you have, tells you which box it belongs in, and opens the empty form.
Reading the result
The result list names the carrier with its USDOT and docket numbers; from it you open the carrier’s detail pages, which cover the authority held and its status, the insurance filings on record and the BOC-3 designation. Three things decide whether a carrier is cleared to haul for hire across state lines: an authority that has been granted rather than pending or revoked, financial responsibility filed at the required level, and a BOC-3 on file. Read each rather than stopping at the first. A company that appears in SAFER with a USDOT number but has no docket in L&I may be a private or intrastate carrier, not a for-hire interstate one. If the detail pages show a pending application, remember the 24-hour note: a filing made yesterday may not be visible yet.
Worked example
A freight broker is about to tender a load to a carrier it has not used before. The carrier’s paperwork shows an MC docket. The broker opens the Carrier Search, picks MC in the docket prefix list, types the digits and submits. The result list shows one company whose legal name matches; the detail pages show the authority as granted, an insurance filing on record and a BOC-3 designation. The broker also opens the SAFER snapshot for the same number to see the out-of-service summary. Had L&I shown the application as pending or the insurance as absent, the load would wait.
Method
The description of the Carrier Search, its fields, the name-matching rules, the 24-hour note and the filing functions were read from the L&I home page and Carrier Search page on November 11, 2026. The tool classifies what you type (a docket prefix with digits, bare digits, or anything else) in your browser and names the field to use; it cannot submit the FMCSA form for you and does not try. The L&I home page carried a notice about the retirement of its registration functions in favour of a new system; the public Carrier Search was live on the day read.
What this does not cover
- The safety record, inspections and crashes, which are on the SAFER snapshot.
- The dollar level of insurance a given carrier must file, which depends on what it hauls.
- Intrastate authority, which is a state matter outside L&I.
- Whether a carrier is a good choice for your freight.

Often assumedA SAFER snapshot is proof that a carrier’s interstate authority is in force.
What the source saysL&I’s Carrier Search is the system the FMCSA describes as covering carriers granted authority or with applications pending; SAFER covers the safety record. [2]
-
Often assumedA carrier that filed its application this morning will show in L&I this afternoon.
What the source saysThe Carrier Search page says new applications will not appear in search results for 24 hours after filing. [1]
-
Often assumedTyping part of a name finds every carrier containing it.
What the source saysL&I matches names that begin with the text; only a leading wildcard searches for names that contain it, and the page says that search takes longer. [1]
-
Often assumedA link can open the L&I search with the number already filled in.
What the source saysThe Carrier Search is a form the FMCSA site submits itself; the page on this site can only tell you which field to type into. [1]

Frequently asked questions
How do I check a trucking company’s operating authority?
Use the FMCSA Licensing & Insurance Carrier Search. Enter the USDOT number or the docket number (MC, FF or MX); the page says either one is all that needs to be entered.
What is the difference between SAFER and L&I?
SAFER’s Company Snapshot is the safety record. L&I is the registration record: authority granted or pending, insurance filings and BOC-3 designations.
Can I search L&I by company name?
Yes, by legal name or DBA name, optionally with a state. Names match from the beginning unless you lead with a wildcard, which the page says is slower.
Why does a new carrier not appear?
The Carrier Search page says new applications do not appear in results for 24 hours after filing.
What are FF and MX docket prefixes?
FF is the docket prefix for freight forwarders and MX for Mexico-domiciled carriers, alongside MC for motor carriers, per the prefix list on the search form.
Who files insurance and BOC-3 documents on L&I?
The home page says insurance companies, financial institutions and BOC-3 blanket agents make financial responsibility filings and Form BOC-3 submissions there through Login.gov.
Does this page search the FMCSA for me?
No. It tells you which L&I field to use and opens the official form; nothing is sent from this page.
Is this site the FMCSA?
