Security company licensing in Washington
Washington State Department of Licensing, Private Security Guard Program licenses security companies here, but we do not yet carry its roster, so we cannot tell you who is on it.
The licence lookup validates a CAPTCHA on the server before any search runs, so it cannot be listed — its county and status filters would otherwise make it ideal. Washington's open data carries only county-level licence counts, no company names, and state law restricts releasing licensee lists for commercial purposes.
Until then, verify a company with the regulator directly, and treat any license number a company gives you as a claim we have not checked.
