What you get on signup
Fleet + authority snapshot
Power units, drivers, authority status, operating type, and out-of-service status — one view, no tab-switching across FMCSA tools.
Cargo + equipment indicators
What the carrier hauls and the operating profile on file. Use it to match carriers to your freight + equipment requirements.
Safety signal preview
FMCSA BASIC measures, crash + inspection counts on a 24-month window, plus alert exposure. Indicators only — not final risk determinations.
The problem
Freight teams waste hours sourcing trucking companies that turn out to be wrong-fit, off-line, or invisible.
DOT and FMCSA records are public, but they aren't search-ready. Local carriers don't show up in generic results. Equipment, cargo, and service-area mismatches don't surface until the load is on the dock.
Pain
DOT and FMCSA data is public but hard to interpret.
SAFER, L&I, BASIC, MCS-150 — each lives in a different tool with a different shape. Putting a single carrier read together takes a half hour.
Pain
Small fleets and local carriers are invisible.
Owner-operators, regional carriers, and specialty trucking companies rarely show up in generic search results. The right carrier for the load may be 30 miles from the pickup.
Pain
Equipment and cargo mismatches surface too late.
Reefer vs. dry van, hazmat-endorsed vs. not, flatbed vs. step-deck — the difference between a successful tender and a bounced load. Carriers' equipment profiles aren't searchable in most directories.
Pain
Operating-status drift hits at the worst moment.
Authority lapses, MCS-150 staleness, OOS flags — invisible until the broker's dispatcher calls and the load is already late.
Pain
Safety reads take cross-referencing across five tools.
BASIC measures, crash counts, inspection rates, OOS percentages, prior incidents — surfaced in five different places. Risk reads take cross-referencing every time.
Pain
Carrier lists go stale fast.
A spreadsheet of vetted carriers from six months ago is half-bad data today. Continuous freshness against FMCSA's authoritative record is the only way carrier lists stay useful.
dotcarriers.io turns DOT/FMCSA records into a searchable motor carrier directory for freight, logistics, and procurement teams.
DOT carrier profiles
Everything your team needs in a structured motor carrier profile.
Each listing is a DOT/FMCSA-powered profile purpose-built for freight, logistics, dispatch, and procurement workflows.
Legal name + DBA
Identity in the FMCSA record. DBA names matter for matching carriers across CRMs and load boards.
ABC Trucking LLC · DBA ABC Logistics
DOT + MC number
Federal IDs. Use them to verify the carrier across SAFER, L&I, and your back-office systems.
USDOT 1234567 · MC-456789
Operating status
Active vs. out-of-service vs. authority-not-confirmed. Catch the difference before tendering a load.
Active authority
Fleet size + drivers
Power units + driver count drive routing, multi-pickup feasibility, and capacity assumptions.
18 power units · 21 drivers
Cargo carried
What the carrier hauls. Match against your freight class and commodity needs.

Safety signals
FMCSA BASIC measures, crash + inspection counts, OOS rates — 24-month window. Indicators only.
No alert · 24mo inspections: 14
Hazmat indicator
Whether the carrier has hazmat authority on file. Critical for hazmat tender matching.
Hazmat: No
Authority history
MCS-150 date, authority granted date, recent changes. Surfaces stale records and authority gaps.
OP-1 since 2019 · MCS-150: 2025-08-14
Insurance filing status
BMC / BOC-3 filings on file. Confirm the carrier carries the federally required minimums before tendering.
BMC-91 on file · BOC-3 on file
Claim + verification status
Whether the carrier has claimed the listing and updated their own profile. Claimed listings carry more recent contact data.
Claimed by operator
Sourcing workflow
From freight requirement to vetted carrier list.

Built for freight + logistics
Built for the teams that move freight.
Each role gets a starting workflow tuned to the carrier data they need.
Freight Brokers
- Problem
- Sourcing carriers by load board alone misses small fleets and local capacity.
- Workflow
- Filter by lane state + cargo type + power-unit tier → save the sourcing list.
- Output
- Ranked carrier shortlist matched to the lane and freight profile.
Shippers
- Problem
- Direct-shipping teams need vetted carriers without paying broker margin.
- Workflow
- Search carriers by garaging state + cargo type + fleet size → review profile + insurance filings.
- Output
- Direct-carrier shortlist with authority + safety + insurance verification.
Logistics Teams
- Problem
- Capacity planning runs on stale carrier spreadsheets that go bad in 90 days.
- Workflow
- Build saved carrier lists by region + commodity + capacity tier; track authority changes.
- Output
- Living carrier-coverage map for the network.
Dispatchers
- Problem
- Carrier-of-last-resort calls waste hours when the original tender bounces.
- Workflow
- Quick DOT lookup → verify operating status → find similar nearby carriers as backup.
- Output
- Fast backup carrier in the same lane with confirmed active authority.
3PL Operations
- Problem
- Multi-customer routing needs broad carrier intelligence across lanes + commodities.
- Workflow
- Filter by service area + commodity + power-unit tier → build customer-specific shortlists.
- Output

Supply Chain Managers
- Problem
- Network resilience planning needs visibility into carrier capacity by region.
- Workflow
- Browse fleet density by state → identify coverage gaps → recruit local carriers.
- Output
- Coverage map + recruit list with carrier capacity and operating profile.
Vendor Sourcing
- Problem
- Specialty trucking sourcing (hazmat, refrigerated, oversize) requires equipment-level filtering.
- Workflow
- Filter by cargo type + hazmat indicator + operating classification.
- Output
- Specialty-equipment carrier shortlist with verified authority.

dotcarriers.io surfaces public DOT/FMCSA records using a documented methodology — see /methodology for source data, refresh cadence, and validation gates. dotcarriers.io does not broker freight, guarantee carrier performance, verify availability, provide legal advice, or make safety/compliance determinations. Users should verify carrier authority, insurance, safety, licensing, availability, and operating status directly with the carrier and official sources before booking.
