Authority Industries Listings

The Authority Industries directory organizes licensed and certified service providers across the United States into structured, searchable entries designed for professional reference and compliance research. Each listing reflects a specific industry vertical, geographic service area, and credential type — giving researchers, procurement officers, and regulatory staff a consistent framework for locating qualified operators. Understanding how entries are constructed and what they do and do not verify is essential before drawing any operational conclusions from the data. The Authority Industries Directory: Purpose and Scope page provides the foundational rationale for why this directory exists and what problems it addresses.

Geographic distribution

Listings span all 50 U.S. states, with density concentrated in states that impose mandatory licensing requirements on service trades. California, Texas, Florida, New York, and Illinois collectively account for a disproportionate share of entries — a pattern consistent with population size and regulatory activity. States operating under contractor licensing boards (California Contractors State License Board, Florida Department of Business and Professional Regulation) generate substantially more verifiable credential records than states relying on municipal-level permitting only.

Entries are tagged with one or more of three geographic scope designations:

1. Local — service area limited to a single county or metropolitan statistical area (MSA)
2. Regional — service area spanning multiple contiguous counties or a defined multi-state corridor
3. National — provider holds credentials or maintains operational capacity in 10 or more states

Geographic scope designations are drawn from provider-submitted documentation and cross-referenced against state licensing databases where those databases are publicly accessible. Discrepancies between claimed scope and verifiable credential records are flagged rather than silently resolved.

How to read an entry

Each directory entry follows a fixed eight-field structure. Readers unfamiliar with the format should consult the How to Use This Authority Industries Resource page before interpreting specific entries.

The eight fields in each listing are:

1. Provider name — legal entity name as registered with the relevant state authority
2. Industry vertical — primary trade classification (e.g., electrical, plumbing, HVAC, environmental services)
3. License number — credential identifier as issued by the licensing body
4. Issuing authority — the named agency, board, or jurisdiction that issued the credential
5. Credential type — distinguishes between a contractor license, a master-level certification, a specialty endorsement, or a business registration only
6. Expiration date — as reported in the source database at last sync
7. Geographic scope — Local, Regional, or National per the definitions above
8. Verification status — one of three states: Confirmed, Pending, or Unverified (see the Verification Status section below)

The most consequential distinction in field 5 is between a contractor license and a business registration only. A contractor license involves demonstrated competency testing, insurance verification, and bonding requirements under state law. A business registration carries none of those prerequisites — it confirms legal entity existence, not professional qualification. Conflating the two is the most common misreading of directory data.

What listings include and exclude

Included:

• Providers holding an active, named license issued by a state licensing board or equivalent authority
• Providers with a verified insurance certificate on file with the issuing authority as of the last database sync
• Specialty endorsements attached to a primary contractor license (e.g., asbestos abatement endorsements, elevator installation endorsements)
• Providers operating under a registered trade name where that trade name is cross-referenced to a licensed legal entity

Excluded:

• Unlicensed trades operating in states that do not require licensure for that trade category
• Federal contractor registrations (SAM.gov registrations) unless the provider also holds a relevant state license
• Providers whose license lapsed, was suspended, or was revoked — even if the provider continues to operate
• Subcontractors who hold no independent license and operate solely under a general contractor's umbrella credential

The exclusion of lapsed credentials is a hard rule, not a judgment call. A credential that expired 30 days prior to a directory sync is treated identically to one expired for 3 years. The Authority Industries Topic Context page provides additional background on how trade licensing standards vary by vertical and why expiration handling is treated categorically.

Verification status

Every entry carries one of three verification status designations. These designations are not quality ratings — they describe the methodology used to confirm the listed credential, not the quality of the provider.

Confirmed — The license number was matched against a publicly accessible state licensing database within the prior 90-day sync window. The credential was active, the legal entity name matched, and no disciplinary flags appeared in the source record.

Pending — The credential documentation was submitted by the provider but has not yet been cross-referenced against a live state database. Pending status does not indicate a problem; it indicates the verification cycle has not yet completed for that entry.

Unverified — The license number could not be matched in any accessible public database. This occurs when a state does not publish a searchable online registry, when the licensing body is a municipality rather than a state board, or when the submitted credential identifier does not conform to the issuing authority's numbering format. Unverified does not mean the credential is invalid — it means independent confirmation was not achievable through available public records.

The distinction between Pending and Unverified matters in procurement contexts. A Pending entry has source documentation on file; an Unverified entry requires the researcher to contact the issuing authority directly. No entry in the directory should be treated as a substitute for primary-source verification when a licensing requirement is legally operative in a given transaction.
