Authority Industries Network: Member Domains and Coverage
The Authority Industries Network is a structured collection of reference-grade web properties organized by industry vertical, each built to surface licensing requirements, verification standards, and credentialing data for professionals and consumers operating across the United States. This page maps the network's member domains, explains how coverage is allocated across verticals, and identifies the criteria that define which topics belong to which properties. Understanding the network's architecture helps users locate authoritative information efficiently and helps licensed professionals understand where their industry data is indexed.
Definition and scope
The Authority Industries Network consists of domain-level properties, each assigned to one or more regulated industry verticals such as construction trades, healthcare, real estate, financial services, and home services. Rather than aggregating all licensing content into a single monolithic database, the network separates coverage by vertical to allow depth of treatment appropriate to each industry's regulatory complexity.
Authority Industries coverage verticals span industries governed by state licensing boards, federal agencies, and national accreditation bodies. A construction trade property, for example, must account for the 50-state patchwork of contractor license types — from Class A General Contractor classifications in Virginia to C-10 Electrical classifications in California — while a healthcare property addresses National Provider Identifier (NPI) registration through the Centers for Medicare & Medicaid Services (CMS) and state medical board requirements simultaneously.
Scope at the network level is defined by whether a profession requires a license, registration, certification, or bond as a legal precondition to work. Professions that rely solely on voluntary credentialing without a legal enforcement mechanism fall outside core coverage, though the distinction between voluntary certification and mandatory licensure is addressed in detail on industry certification vs. licensure.
How it works
Each member domain in the network operates as a standalone reference property with its own URL namespace, editorial scope, and topical coverage map. Content across properties is coordinated at the network level to prevent duplication and to ensure cross-vertical topics — such as reciprocal licensing across states or bonding requirements — are treated with consistent definitions.
The operational structure follows this sequence:
- Vertical assignment — A regulated industry is mapped to one primary domain based on licensing body type (state board, federal agency, or accreditation council).
- Coverage depth mapping — Each domain's topic inventory is scoped to the licensing lifecycle: application, examination, issuance, renewal, reciprocity, and enforcement.
- Verification alignment — Listings and reference data are cross-checked against state licensing board directories and federal registries, following the standards described in licensed authority verification standards.
- Update cadence — Statutory changes, fee adjustments, and board policy shifts trigger review cycles tied to official publication dates from relevant agencies.
- Cross-network linking — Where a topic spans multiple verticals (bonding thresholds, for example, apply to contractors, mortgage brokers, and notary publics), authoritative treatment is placed on the most relevant domain and referenced from others.
Member domains do not republish license records directly from state databases. Instead, they provide structured guidance on how to interpret, locate, and act on records through primary sources such as individual state licensing board portals.
Common scenarios
Three patterns account for the majority of network usage:
Consumers verifying a professional's license status — A homeowner researching an HVAC contractor in Texas can use the network to identify that HVAC work requires a license from the Texas Department of Licensing and Regulation (TDLR) and then navigate directly to TDLR's public verification portal. The consumer guide to hiring licensed professionals supports this pathway with industry-specific lookups.
Licensed professionals researching reciprocity — A licensed electrician moving from Nevada to Arizona needs to understand whether Nevada's reciprocity agreements with Arizona eliminate the need to retake a licensing exam. Network properties map these state-to-state agreements by trade, drawing on published reciprocity schedules from each state's licensing board.
Businesses auditing multi-state compliance — A national home services company operating in 12 states must track license requirements, bond minimums, and insurance thresholds across jurisdictions. The network's vertical properties provide a structured entry point, though final compliance determinations require direct consultation with each jurisdiction's licensing authority.
The contrast between single-state operators and multi-state businesses is significant: a plumber licensed only in Oregon faces straightforward renewal cycles managed through the Oregon Construction Contractors Board, while a regional plumbing company operating in Oregon, Washington, Idaho, and California must maintain four separate licensing relationships with distinct continuing education, bond, and fee requirements. Multi-vertical licensing requirements by industry addresses this complexity in detail.
Decision boundaries
Not all licensing-adjacent content falls within network scope. The following distinctions govern what is and is not covered:
In scope: State-issued contractor licenses, professional licenses (medical, legal, financial, real estate), federal registrations with legal work-authorization consequences (NPI, NMLS, USDOT numbers), and bond/insurance thresholds mandated by statute.
Out of scope: Voluntary trade association memberships with no legal enforcement mechanism, manufacturer certifications that do not affect legal work authorization, and employer-issued credentials without regulatory standing.
The boundary between "licensed" and "certified" is the central decision point. As the industry glossary defines, licensure carries legal authority — working without it exposes both the professional and the consumer to statutory penalties — while certification typically signals competency without creating a legal bar to practice. When a certification is required by statute as a precondition to licensure (EPA 608 certification for HVAC refrigerant handling, for example), it crosses the threshold into network scope.
Properties within the network do not adjudicate disputes or render legal interpretations. Where enforcement actions, complaint records, or disciplinary histories are relevant, users are directed to the licensing board of jurisdiction as the authoritative source.
