FAQ

Is this legal to use? Yes. The source is the State of Washington's official open-data portal. The dataset "L&I Contractor License Data - General" is published under the Open Data Commons Public Domain Dedication and License (PDDL).

Does "effective date" mean a brand-new license? It means the start of the current license term, so the results include both new licenses and renewals. A UBI number you haven't seen before usually indicates a new business.

Common questions about the Washington contractor leads list

How do I get the Washington contractor leads list without coding? Press Try for free, adjust the filters (or keep the defaults), press Start, then open the Storage tab and export the results as Excel, CSV or JSON. A run usually finishes in seconds.

How much does it cost? Free to try: Apify's free plan ($5/month credit, no credit card) covers about 1,600 records a month. After that it is $3.00 per 1,000 results (pay per result), plus a fraction of a cent per run. You only pay for rows you get.

Can I get new records automatically every day or week? Yes. Save your filters as a task and add a Schedule (daily or weekly). Connect Google Sheets, Slack, email, Zapier, Make or n8n under Integrations to receive each new batch.
