Authority Industries Directory: Purpose and Scope
The Authority Industries Directory is a structured reference resource cataloguing licensed, bonded, and verified businesses operating across regulated trades and professions in the United States. This page defines the directory's purpose, explains what categories of businesses and credentials are included, describes how listing determinations are made, and outlines the geographic reach of the database. Understanding these parameters helps readers evaluate how to interpret entries and why the directory exists as a distinct resource from general business listings.
Purpose of this directory
Licensing failures in the contracting and professional services sectors produce measurable consumer harm — unlicensed work routinely voids homeowner insurance claims, creates liability gaps that leave clients uncompensated, and in trades governed by public safety codes, can produce structural or health hazards with no clear recourse. The Authority Industries Directory exists to reduce the friction of license verification by consolidating publicly available credential data into a structured, searchable format organized by trade and state.
The directory does not replace state licensing board records as the authoritative legal source. Instead, it functions as a navigation layer — directing users toward the right verification pathway for a given industry and jurisdiction. A contractor verified through a state board database holds a different credential status than one appearing only in a self-reported listing, and the directory is designed to reflect that distinction clearly. For a full explanation of the standards applied to each entry, see Licensed Authority Verification Standards.
The directory serves two distinct audiences. Consumers use it to identify whether a specific business holds the credentials legally required to perform work in their state. Industry professionals use it as a reference when evaluating subcontractors, assessing reciprocal licensing status across state lines, or confirming that a competitor holds the certifications they claim. Both use cases require the same underlying data quality: entries must be traceable to a public, authoritative source.
What is included
The directory covers businesses and individual practitioners operating in trades and professions where licensure, bonding, or certification carries a legal or regulatory requirement under state or federal law. Included categories span general contracting, electrical, plumbing, HVAC, roofing, pest control, real estate, insurance, healthcare-adjacent services, and financial advisory trades — all sectors in which operating without proper credentials constitutes a civil or criminal violation in at least one U.S. jurisdiction.
Each entry typically includes:
- Business or practitioner legal name as registered with the relevant licensing authority
- License type, license number, and issuing state board
- License status (active, inactive, expired, or suspended) as of the last verified update
- Bond and insurance confirmation where publicly available
- Trade or professional category using standardized classification
- State(s) of licensure, including any reciprocal licenses
Entries do not include customer reviews, subjective quality ratings, or pricing data. The directory is a credential reference, not a marketplace. For context on how licensure differs from certification in professional contexts, Industry Certification vs. Licensure provides a detailed breakdown of the legal and practical distinctions.
Businesses appearing in the directory are not endorsements. A listed entity with an active license may still have open complaints, disciplinary history, or pending revocation proceedings — data that is sourced from separate regulatory records and linked where available.
How entries are determined
Entries are determined by a combination of trade eligibility criteria and source-based verification. Not every business that holds a license qualifies for inclusion; the directory applies threshold criteria to ensure that listed entries meet minimum documentation standards.
The Authority Industries Listing Criteria page defines these thresholds in full. At a high level, inclusion requires that a license number be verifiable against the issuing state board's public database at the time of entry. Businesses that cannot be cross-referenced to a named, reachable public source — such as a state licensing board portal, a federally maintained registry, or a court of record — do not appear in the directory regardless of self-reported credentials.
A useful contrast exists between primary-source entries and cross-referenced entries. Primary-source entries are populated directly from state board exports or official public APIs where those data feeds are available. Cross-referenced entries begin with a business submission and are then verified against the applicable public registry before publishing. Primary-source entries carry a higher confidence rating and are labeled accordingly. The Authority Industries Data Accuracy Policy governs update frequency, correction procedures, and the process for flagging outdated records.
Businesses seeking to submit or update a listing follow a documented intake process described at How to Submit a Business Listing. Submissions that cannot be verified within 30 days of intake are not published.
Geographic coverage
The directory covers all 50 U.S. states and the District of Columbia. Coverage depth varies by state because licensing requirements themselves vary — 50 U.S. jurisdictions each maintain independent licensing board structures, and the scope of regulated trades differs significantly. Texas, California, Florida, and New York maintain among the most extensive contractor and professional licensing databases in the country, which translates to denser directory coverage in those states. States with limited centralized licensing infrastructure, such as those that delegate licensure to county or municipal authorities, may have thinner directory representation reflecting the fragmented underlying data.
The directory does not cover U.S. territories, Canadian provinces, or international jurisdictions. For trades where multi-state practice is common — such as interstate trucking, pipeline construction, or multi-state financial advising — the directory captures each state license as a discrete entry rather than treating a federal or reciprocal credential as a single unified record. The practical implications of this distinction are addressed in National Licensing vs. State Licensing and Reciprocal Licensing Across States.
State licensing board contact information and verification portals for all 50 states are catalogued separately in the State Licensing Board Directory, which serves as the direct verification reference for any credential listed here.
