CarrierDataHub

Methodology

CarrierDataHub stores company records as structured data and renders static pages from those fields. A page shows what the source data says and leaves fields blank when they are not present — it does not fill gaps with invented values.

Data source

Records in this directory are sourced from the FMCSA Company Census File, a public dataset released by the Federal Motor Carrier Safety Administration through the U.S. Department of Transportation's open data platform. The file contains motor carrier identification and census fields for registered entities.

The import pipeline reads the CSV, normalizes field names and formats, removes records with corrupt or implausible values, scores each record for field completeness, and applies an indexability gate. Only records that pass the gate are included in indexable company pages.

Current build

  • Total company records in directory: 5,000
  • Records explicitly allowed to index: 5,000
  • Source CSV rows processed: 4,437,575
  • States with at least one record: 116
  • Cities represented: 80,439
  • Import timestamp: 2026-05-18T08:10:52.178Z

Indexability gate

A company page is eligible for search engine indexing only when all of the following are present and valid:

  • Legal name
  • USDOT number
  • State
  • City or physical address
  • Known entity type (carrier, broker, freight forwarder, or mixed)
  • Operating status
  • Source name and source data last-updated date
  • Field-completeness quality score of 70 or higher (out of 100)
  • Not marked as a duplicate, placeholder, or sample record
  • Explicitly allowed to index after quality review

State and city pages are also indexable when they contain at least one company that passes the above gate. Pages with no qualifying records are served but marked noindex and excluded from the sitemap.

Quality scoring

Quality scores summarize whether core fields are present. Points are awarded for: legal name, USDOT number, state, city, entity type, operating status, authority status, fleet fields (power units and drivers), source name, and source update date. The maximum score is 100. Records scoring below 70 are excluded from indexable pages.

The score is not a safety rating. A high-scoring record is one with complete public fields, not a company that CarrierDataHub has evaluated or approved.

Data handling

Missing fields are left blank. Fleet size ranges use bucketed values derived from reported power-unit counts and are labelled as estimates to reduce false precision from stale data. Addresses are displayed as imported; they may lag behind official filings. The site does not impute, interpolate, or generate field values.

What CarrierDataHub does not do

  • Does not rate, rank, or recommend companies.
  • Does not verify real-time operating authority or insurance status.
  • Does not certify that any company is safe, active, or qualified for a shipment.
  • Does not replace official FMCSA systems.
  • Does not provide legal, safety, insurance, or financial advice.
