US Contractor License Lookup & Lead Lists (WA, OR, TX, NY) — official open data

Verify a contractor's license in seconds, or export a list of licensed contractors by trade, city, ZIP or expiration date — from the official state registries, not from a third-party directory.

The Actor queries the open-data registries that four state licensing agencies publish and refresh daily:

State	Registry	What it contains	Records
WA	Department of Labor & Industries — Contractor License Data	business, principal, license type & specialties, status, effective/expiration dates, address, phone, UBI	~160,000
OR	Construction Contractors Board — Active Licenses	business, responsible individual, endorsement (residential/commercial level), county, phone, bond company & amount, insurance company & amount	~56,000
TX	Department of Licensing and Regulation — All Licenses (contractor & electrician types)	business, owner, license type (A/C contractor, electrical contractor, master/journeyman electrician …), county, expiration	~100,000 contractor-type
NY	Department of Labor — Contractor Registry Certificates (public-work contractors)	business, DBA, business type, address, phone, status, issue/expiration, debarment and wage-assessment flags	~15,000

Every record is normalised to one schema, so a multi-state export is a single table.

A summary record lists, per state, how many rows were fetched, how many were emitted, and the exact filter that was sent to the registry.

Why use it

• Verification — check that a subcontractor's license is active before you sign, with the registry's own expiration date, bond and insurance details (OR).
• Lead generation — insurers, bonding agents, building-material suppliers, software vendors and marketing agencies sell to licensed contractors. Filter by trade and location, export names and phone numbers, load into your CRM.
• Renewal marketing — expiringWithinDays: 60 gives you every license that expires in the next two months (WA, NY server-side; OR, TX client-side).
• Risk & compliance — NY flags debarment and outstanding wage assessments.
• AI agents — call it as a tool: "Is license ECOSTSC758NN active?" or "List HVAC contractors in Houston".

How to use

1. Pick the states.
2. Either type a search (business name, principal, or license number — 'contains', case-insensitive), an exact license number, or leave the search empty and use the filters (trade, city, county, ZIP prefix, expiring window).
3. Run. Download JSON / CSV / Excel, or read the dataset through the API.

Pricing

Pay-per-event: a small fee per run plus a fee per license record returned. A verification of one license costs one record; a 1,000-contractor lead list costs 1,000 records.

Coverage notes & roadmap

• Fields differ by state: Texas publishes no address or phone; Oregon publishes bond and insurance; New York publishes compliance flags.
• Data is exactly what the agency publishes; check the sourceDataset link for the registry's own disclaimer. These are public records intended for verification and business use. Do not use them for consumer credit, employment or tenant screening decisions (FCRA).
• On the roadmap: California (CSLB public data portal), Florida (DBPR public-records extracts), Arizona ROC, Nevada NSCB. Vote by opening an issue on the Actor page.
