National Trade Authority: Your Comprehensive Resource
The Authority Industries Directory is a structured reference resource cataloging licensed, bonded, and credentialed trade contractors operating across the United States. This page defines the directory's purpose, explains what categories of entries qualify for inclusion, describes the criteria governing how listings are evaluated, and outlines the geographic scope of coverage. Understanding these parameters helps property owners, project managers, and procurement professionals interpret what a listing represents and what it does not.
Purpose of this directory
The Authority Industries Directory exists to close an information gap that affects trade procurement at scale. Across the US construction and skilled trades sector — which the US Bureau of Labor Statistics tracks across more than 30 distinct occupation classifications — sourcing verified, compliant contractors without access to a centralized reference has forced project stakeholders to rely on fragmented state licensing boards, word-of-mouth referrals, or unverified aggregator platforms that impose no documented standards.
This directory functions as a reference layer, not a marketplace. It does not facilitate transactions, accept bids, or negotiate contracts. Its role is to surface the existence and standing of trade contractors whose credentials, insurance status, and compliance history meet a defined threshold of documented verification. The distinction matters: a marketplace optimizes for conversion; a reference directory optimizes for accuracy and completeness of record.

What is included
Entries in the Authority Industries Directory fall into two categories: primary trade listings and specialty or ancillary trade listings.
Primary trade listings cover contractors whose principal business activity belongs to one of the recognized construction and skilled trade verticals — electrical, plumbing, HVAC, general contracting, roofing, structural concrete, and 12 additional categories defined in the Authority Industries Trade Categories Explained reference page.
Specialty or ancillary trade listings cover contractors whose scope is narrower or whose work typically supports primary trade activity — fire suppression installation, industrial coating, utility locating, and similar disciplines.
Each listing record includes the following structured data points:
- Legal business name and registered state of operation
- Active state license number(s) and issuing authority
- Bond type, bonding company, and coverage amount (where publicly verifiable)
- Insurance class (general liability minimum, workers' compensation status)
- Trade category classification using the directory's multi-vertical trade classification system
- Geographic service radius or named service states
- Listing status: Active, Conditional, or Under Review
Entries do not include subjective reviews, star ratings, or consumer sentiment scores. The Authority Industries Trade Authority Ratings Explained page describes the objective standing indicators that do appear on listings and how each is calculated.
How entries are determined
Inclusion in the directory is not automatic and is not self-certified. Contractors submit documentation through a defined intake process described in the Authority Industries Submission and Onboarding Process page. Submitted credentials are cross-referenced against three primary verification sources:
- State licensing board records — pulled from the official licensing database of each state where the contractor claims active licensure
- FEIN-linked insurance certificates — reviewed against policy minimums established in the Authority Industries Insurance and Bonding Requirements framework
- Federal contractor compliance data — where applicable, cross-checked against SAM.gov and relevant federal debarment lists
A listing is approved only when all three verification checks return consistent and current results. If a discrepancy exists between submitted documentation and official database records, the application enters a Conditional status queue. Conditional listings are disclosed as such and are not treated as fully approved entries.
Listings are not permanent. The Authority Industries Renewal and Recertification Cycle page specifies the interval at which re-verification is required — currently tied to the shorter of the contractor's license renewal period or a 12-month calendar cycle, whichever comes first. Entries that fail re-verification are moved to Under Review status and may be delisted.
The contrast between this process and standard aggregator platforms is direct: most national contractor aggregators rely on self-reported license numbers with no cross-reference to state board records. The Authority Industries vetting model requires database-confirmed, active status at the time of listing approval.
Geographic coverage
The directory covers all 50 US states plus the District of Columbia. Coverage is not uniform in density — states with larger construction markets (California, Texas, Florida, and New York account for a combined 38% of US construction put in place, per US Census Bureau data) produce proportionally higher entry volumes.
Entries are organized by primary state of licensure. Contractors licensed in multiple states appear under each state where an active license is confirmed, rather than under a single "national" catch-all entry. This structure ensures that a user assessing contractor options in a specific state sees only contractors with verified standing in that jurisdiction.
For a visual reference of coverage distribution by state, the Authority Industries National Coverage Map provides a current geographic breakdown. States where the directory has fewer than 10 active listings are flagged on the map as low-density coverage zones — a transparency measure that prevents the directory from implying depth of coverage that does not yet exist.
Territories (Puerto Rico, Guam, the US Virgin Islands) are outside the current scope of the directory. Contractor licensing in those jurisdictions operates under separate statutory frameworks, and verification against those frameworks has not yet been integrated into the directory's cross-reference system.
