# CarrierScrub

> CarrierScrub gives freight brokers a dated GO / CAUTION / STOP verdict on a motor carrier from its USDOT or MC number, built by fixed, published rules from FMCSA's own operating-authority, insurance, revocation and out-of-service records. Three carriers a day are free with no account. Pay-as-you-go is $0 a month with 25 lookups, then $1 each; Small Brokerage is $79/mo with no monthly lookup cap; Agency is $249/mo.

**What it does**

- **One carrier, go or no-go.** Enter a USDOT or MC number, or find it by company name, and get GO, CAUTION or STOP with plain-language reason codes, each stating the FMCSA fact behind it and the date FMCSA published it. Free for 3 distinct carriers a day, with no account and no card: https://carrierscrub.com/dot-number-lookup
- **A whole carrier list.** Upload a CSV, Excel or PDF of up to 1,000 USDOT or MC numbers and get a verdict for each. Without an account you see the list's price and its first 3 verdicts; on Pay-as-you-go it uses the 25 free monthly lookups, then $1.00 each; Small Brokerage and Agency run it with no monthly lookup cap: https://carrierscrub.com/upload
- **Monitoring.** A watchlist emails the brokerage when a watched carrier's verdict or its contact details on FMCSA's record change. Included at $0 on Pay-as-you-go.
- **A record for the load file.** Numbered print packets carry a public verification link, and the whole brokerage shares one lookup history, so a broker can show what was checked and when. Small Brokerage and Agency add a vetting file: the brokerage's written carrier-selection policy and every check by carrier or by load, with load numbers, printable and as a CSV.
- **Dispatcher check (Shield).** Compares the phone number, and optionally the email, that a dispatcher contacts the broker from with the carrier's FMCSA registration (the check FMCSA recommends doing in SAFER), and adds an independent verification service's report on whether the line and email are valid and associated with the carrier. $0.50 a check; Small Brokerage includes 100 a month and Agency 500. It states facts about a phone number and an email; it does not identify the caller and cannot rule out caller-ID spoofing.
- **Deep check.** Looks past FMCSA's record for one carrier: USPS data on its registered address, its Google listing, its website and domain age, and whom business phone records register its FMCSA phone number to. $5 (5 credits), 3 free once per brokerage. Shown beside the verdict; it never changes it.
- **API and MCP server, on every plan.** REST API keys (OpenAPI description at https://carrierscrub.com/openapi.json) and an MCP server at https://carrierscrub.com/mcp let a TMS, a script or an AI assistant run the same lookup and get the same verdict. On Pay-as-you-go and Small Brokerage, API lookups use 25 free a month, then $1.00 each, up to 100 requests a day; Agency is unlimited, up to 1,000 requests a day. Setup: https://carrierscrub.com/docs
- **For carriers and movers.** A carrier can see the verdict brokers see and what fixes it with FMCSA (https://carrierscrub.com/for-carriers); a household can check what FMCSA licenses a moving company for before paying it (https://carrierscrub.com/mover-check).

**Who it fits**

A freight broker or small brokerage that wants a documented go or no-go on each carrier before tendering a load, without an onboarding-suite contract; anyone checking a list of carriers at once; and developers adding FMCSA carrier vetting to a TMS, a script or an AI agent. CarrierScrub is software only: it does not broker freight, hold funds or extend credit. It does not carry user-submitted carrier reports such as Carrier411's FreightGuard, safety history older than 24 months, or BASIC percentiles, and it does not collect carrier packets or certificates of insurance the way an onboarding suite such as RMIS does. The comparison pages below say, with dated sources, where each alternative goes further.

**How a verdict is made**

- The rules are fixed and published, identical on every plan including the free lookup, and not editable per account: https://carrierscrub.com/methodology
- A check reads the carrier's current FMCSA Motus record where one exists, and otherwise FMCSA's legacy Licensing & Insurance file, which FMCSA stopped updating on 14 May 2026. A stored record is rechecked against FMCSA once it is more than a day old, and every result names the record it used and that record's date.
- Motus also flags a missing required cargo insurance or bond filing, and mail to the carrier returned undeliverable; each reads CAUTION.
- Safety rating, roadside out-of-service history and crash history come from FMCSA's Safety Measurement System snapshot and are dated to it. BASIC percentiles are not shown because FMCSA does not publish them for property carriers, and a carrier that has never been rated is shown as unrated, not as a pass.
- Reason codes state facts FMCSA published and their dates; none allege fraud or draw a conclusion about a named company. Paid lookups also check the phone and address on the carrier's FMCSA registration (is the number in service; is the address a real postal address, a PO box or a PMB), shown beside the verdict and never part of it.
- A carrier that believes a result is wrong can have it corrected free, and lookup data is never sold or used to profile a carrier.
