Verticals Covered by Authority Industries: A Complete List

Authority Industries operates a network of reference-grade directory properties, each anchored to a specific industry vertical within the United States. This page catalogs the full scope of verticals covered, explains how vertical assignment functions within the network, and draws clear boundaries around what qualifies for inclusion. Understanding the vertical structure is essential for anyone using the directory to locate authoritative resources, evaluate coverage gaps, or assess whether a given industry falls within the network's scope.

Definition and scope

A "vertical," in the context of the Authority Industries network, refers to a discrete industry or professional sector assigned its own dedicated directory domain. Each vertical domain operates as a subject-matter reference point for that sector — not a general aggregator. The network spans industries regulated at the federal or state level, professions with licensing requirements, and service categories where consumers face meaningful asymmetry of information.

The current network covers verticals across healthcare, legal services, financial services, home improvement, real estate, insurance, education, automotive, and skilled trades. These are not arbitrarily chosen: each corresponds to a sector where the Bureau of Labor Statistics Occupational Outlook Handbook documents a substantial and stable workforce, or where federal agencies such as the Federal Trade Commission (FTC) or the Consumer Financial Protection Bureau (CFPB) maintain active regulatory oversight. The logic of vertical selection is explained in greater detail on the authority-industries-covered-verticals page.

How it works

Each vertical in the network receives an independent domain structured to serve as the authoritative directory for that sector at national scale. The domain operates under standards described in national-scope-directory-standards, which govern how listings are sourced, verified, and maintained.

The assignment of a vertical to a dedicated domain follows a defined process:

1. Sector identification — The industry is evaluated for regulatory density, public information need, and workforce size using data from sources including the BLS and federal agency rulemaking records.
2. Domain architecture decision — The vertical is assessed for whether a standalone domain or a sub-section of an existing hub domain is appropriate. High-volume, independently regulated sectors receive standalone domains.
3. Listing criteria definition — Each vertical domain establishes its own listing eligibility rules, calibrated to the licensing or credentialing requirements specific to that sector.
4. Quality signal mapping — Signals such as state licensure status, accreditation body membership, and complaint record availability are mapped to the vertical's listings per the framework described in authority-industries-quality-signals.
5. Ongoing editorial review — Listings are subject to periodic accuracy review; the process for corrections is documented at updating-or-correcting-a-listing.

The distinction between a vertical domain and the hub network is structural: the hub (nationalverticalauthority.com) provides network-level navigation and meta-information, while each vertical domain provides sector-specific depth.

Common scenarios

The vertical structure addresses three recurring information scenarios faced by users of the directory network:

Scenario 1: Locating a licensed professional in a regulated sector. A user seeking a licensed electrician, certified financial planner, or accredited home inspector benefits from a directory that reflects licensing board data rather than self-reported claims. The vertical domain for that sector indexes entries against state licensing databases where such records are public. The CFPB and state insurance commissioners, for example, maintain public registries that serve as baseline verification inputs for financial and insurance verticals.

Scenario 2: Comparing coverage across adjacent verticals. Home improvement and real estate are adjacent but distinct. A general contractor falls under the home improvement vertical; a real estate attorney or title company falls under the legal or real estate vertical, depending on function. These boundaries prevent dilution of sector-specific signals and ensure that a user browsing the real estate vertical does not encounter listings more appropriate to construction trades. The mechanics of how sibling domains maintain these distinctions are covered at how-sibling-domains-differ-from-hub.

Scenario 3: Identifying coverage gaps. Not every industry has a fully built-out vertical. Some sectors are identified as candidates for network expansion but have not yet reached the threshold for a dedicated domain. The national-vertical-coverage-gaps page documents which sectors are in development versus fully operational.

Decision boundaries

Not every service category qualifies as a discrete vertical within the Authority Industries framework. Three primary boundaries govern inclusion:

Regulatory threshold: A vertical must correspond to a sector where at least one federal agency exercises rulemaking authority, or where 40 or more US states maintain a licensing or registration requirement for practitioners. Sectors below this threshold may be incorporated as subcategories within an existing vertical rather than assigned independent domains.

Workforce materiality: Sectors with fewer than 50,000 employed workers nationally (per BLS Occupational Employment and Wage Statistics) are evaluated for consolidation with adjacent verticals rather than standalone treatment.

Consumer information asymmetry: The vertical must represent a market where consumers cannot readily assess provider quality without structured reference information. Commodity markets where price and product specifications are fully transparent do not meet this criterion.

The contrast between a qualifying and non-qualifying sector is illustrated by comparing licensed home health aides (regulated in all 50 states, subject to CMS Conditions of Participation per 42 CFR Part 484) versus general housekeeping services (no federal licensing framework, no mandatory credentialing). The former qualifies as a vertical; the latter does not under current criteria.
