MC number lookup.
Where the Federal Motor Carrier Safety Administration publishes a carrier’s record, how to open it from an MC number, and how to read the snapshot you get back. This page builds the official link and sends nothing anywhere.
Short answer: An MC number is looked up on the FMCSA SAFER system’s Company Snapshot, which the agency describes as a concise electronic record of a company covering identification, size and commodity information, and safety data including the safety rating (if any), a roadside out-of-service inspection summary, and crash information. The page says users can search by DOT Number, MC/MX Number or Company Name and that the snapshot is available via an ad-hoc query (one carrier at a time) free of charge. Enter the number above and the tool opens the snapshot for that MC/MX number in a new tab. For the authority itself, its status and the insurance on file, the separate Licensing & Insurance system is the record.

What the Company Snapshot shows
SAFER is the FMCSA’s public query system. Its Company Snapshot page calls the record a concise electronic record of a company and lists what it covers: identification, size and commodity information, plus safety data. The safety data is the part most people are after, and the page names three pieces: the safety rating, if any, a roadside out-of-service inspection summary, and crash information. The agency says the snapshot is available via an ad-hoc query, one carrier at a time, free of charge, which is why this page builds one link per search and never runs a bulk or automated call. The GET address the tool opens was checked on November 11, 2026; SAFER accepts the query parameter for MC/MX numbers, USDOT numbers and names.

MC number, MX number, USDOT number
The three numbers answer different questions. A USDOT number identifies the company in FMCSA’s safety systems; an MC number is the docket number of an operating authority for interstate for-hire transport; an MX docket is the Mexican-carrier equivalent. SAFER lets you reach the same snapshot from any of them, which is convenient but also why people confuse them: the snapshot you reach by MC number is indexed by the company’s USDOT number, and the MC number appears on it as one of the identifiers. The page on this site comparing MC numbers and USDOT numbers goes through the difference; the short version is that a company can have a USDOT number without any MC authority, but not an active MC authority without a USDOT number.
How to use the lookup
Pick MC or MX number, type the digits (the tool strips an MC-, MX- or USDOT prefix and checks that only digits remain, because no official page publishes a digit-count rule), and press Build link. Open the link; SAFER returns the snapshot for that carrier, or a message that no record matches. For a name, SAFER returns a keyword list of matching companies; open the one you mean. Read the identification block first and make sure the legal name and any DBA match what you were given, then the safety rating line (many carriers have none), then the out-of-service summary and crash block. If the number you were given reaches a different company, or no record, stop and ask the carrier for its USDOT number.
Worked example
A shipper is quoted by a carrier whose email signature shows an MC number. You choose MC or MX number, type the digits and open the snapshot. The identification block shows a legal name that matches the quote and an entity type of carrier. There is no safety rating line, the out-of-service summary shows a handful of inspections, and the crash block is empty. That tells you the company exists in FMCSA’s records under that number; it does not tell you whether the authority is active today or whether insurance is on file. For that you open the Licensing & Insurance carrier search, covered on the operating authority page linked above, and check the authority status and the insurance filings.
Method
The description of the snapshot, the three search options and the one-carrier-at-a-time wording were read from the SAFER Company Snapshot page on November 11, 2026. The tool checks the shape of what you type in your browser, builds the SAFER address with the number or name encoded into it, and shows it as a link; no request is made from this page and nothing is stored. The record belongs to the FMCSA and is only current on SAFER.
What this does not cover
- Whether the operating authority is active, pending or revoked, and the insurance on file: those are on the Licensing & Insurance system.
- The Safety Measurement System scores behind the snapshot, which have their own site and disclaimer.
- Brokers and freight forwarders, which have docket numbers but no vehicles; see the broker page linked above.
- Intrastate-only carriers, which may have no MC number at all.
