National Vertical Authority

The Professional Services Authority Provider Network is a structured reference index mapping established domains of professional and commercial activity across the United States to authoritative information resources. This page explains what the provider network is, which industries and entities qualify for inclusion, and where its coverage boundaries fall. Understanding the provider network's scope helps readers locate relevant verticals efficiently and interpret providers with appropriate context.

How to use this resource

The provider network organizes industries into discrete verticals, each corresponding to a defined domain of economic or regulatory activity. Readers navigating the index can move from a broad industry category down to vertical-specific reference pages, operator profiles, and regulatory context documents. The Professional Services Authority Providers page serves as the primary entry point for browsing available verticals by category.

Effective use of the provider network depends on understanding how verticals are classified. Each industry vertical is assigned to a parent category based on primary activity — for example, a roofing contractor network falls under construction trades rather than property services, even though both classifications could apply. When a business or operator spans two categories, the provider network applies a primary-vertical rule: classification follows the activity that accounts for the majority of revenue or regulatory exposure.

For context on how individual domain properties relate to the broader index structure, the Multi-Vertical Provider Network Structure page explains how sibling domains and hub properties divide subject coverage without duplication. Readers seeking definitions of provider network-specific terminology can consult the Professional Services Authority Glossary.

A numbered breakdown of typical navigation paths:

1. Identify the vertical — locate the industry category matching the subject of inquiry.
2. Review the vertical overview — each vertical page summarizes scope, key operators, and regulatory context.
3. Access operator or entity providers — individual providers link to primary sources, licensing bodies, and reference documents.
4. Cross-reference coverage gaps — where a vertical is noted as partially covered, the National Vertical Coverage Gaps page documents known absences and planned additions.

Standards for inclusion

Inclusion in the network is not automatic. Industries and entities are evaluated against a defined set of criteria before a provider is created or approved. The Professional Services Authority Vetting Criteria page publishes the complete evaluation framework; the core standards are summarized below.

Industry-level inclusion requires that the vertical meet three thresholds:

Entity-level inclusion applies a separate standard. Individual operators, firms, or associations are verified only when they hold active credentials from a named licensing authority, carry verifiable registration in at least 1 state jurisdiction, or are recognized by a federally chartered or nationally scoped industry body. Entities that operate solely at the local or county level without state-level registration fall outside national provider network scope.

The contrast between national and local scope is a frequent decision point. A contractor licensed in 12 states qualifies for national provider network treatment; a contractor licensed in a single municipality does not, regardless of operational size. The National vs. Local Authority Provider Network Distinctions page documents this boundary in detail.

How the provider network is maintained

Providers are reviewed on a defined cycle. Vertical-level entries are audited annually against regulatory and licensing data. Entity-level providers are flagged for review whenever a primary source — such as a state licensing board database or federal registration system — records a status change.

The provider network draws exclusively from named public sources: federal agency databases, state licensing portals, published industry association member rolls, and statutory regulatory registers. No proprietary or third-party data aggregator is used as a primary source. The Professional Services Authority Data Sources page enumerates all source types in use and notes where data freshness constraints apply.

Corrections to existing providers follow the process described on the Reporting Inaccurate Network Information page. Submitted corrections are evaluated against the originating primary source before any change is applied. The provider network does not accept self-reported corrections from verified entities without independent verification from the source record.

Editorial decisions — including which verticals to add, merge, or retire — are governed by the framework published on the Professional Services Authority Editorial Policy page. Policy updates are documented with effective dates in the change log maintained on that page.

What the provider network does not cover

The provider network excludes four categories of subject matter regardless of industry size or prominence:

1. Local-only operators — entities without state-level licensure or multi-state registration fall below the national scope threshold.
2. Unlicensed trades — industries or activities that operate without any recognized regulatory framework are excluded because no verifiable credentialing basis exists for provider.
3. Financial products and securities — investment vehicles, securities offerings, and insurance products are excluded due to the specialized compliance infrastructure those sectors require; dedicated regulatory reference sites cover that domain separately.
4. Individual professionals in licensed-firm contexts — where a profession licenses firms rather than individuals (general contracting in most states, for example), individual practitioners are not verified as independent entries.

The provider network also does not function as a consumer referral service, lead-generation index, or paid placement system. Providers reflect public record status, not commercial relationship. Advertising placements, if any, are structurally separated from editorial providers and do not influence inclusion or ranking within the index.
