Contractors

Use our Verify tool to see if a business you want to contract with has an active contractor registration; an active and paid-to-date workers' comp account covering any employees. At the same time, you can check for safety violations, other information, lawsuits against their surety bond and more.

Verify a Contractor, Tradesperson or Business will allow you to:

  • Look-up subcontractors and tradespeople.
  • Verify a contractor has an active license.
  • Verify a tradesperson is certified.
  • Verify a contractor has an active workers' comp account that is current.
  • See if the contractor has safety citations or other infractions.
  • Find out if they have any lawsuits against their bond.
  • Complete a tracking request for a subcontractor with an active worker's comp account.
  • Print the "Certificate of Workers' Comp Coverage."

You can search for a contractor by their:

  • L&I employer account ID or Contractor License Number.
  • UBI number (business license number). OR
  • Full or partial business or owners name.

Use these tools to learn about hiring subcontractors or "Independent Contractors" and avoid prime contractor liability.

If you are a contractor hiring a subcontractor, be sure to complete a tracking request for those with active coverage. If the subcontractor fails to pay workers' comp premiums or renew their contractor registration, or if their electrical contractor license is suspended or revoked within one year of the request, L&I will send you a notification letter.

You might be an employer and not know it

In some cases, an "independent contractor" is actually a worker for whom you must do such things as pay workers' comp premiums, meet wage and hour requirements, pay unemployment tax, etc. Not understanding your requirements can leave your business vulnerable to unwanted penalties and event lawsuits. Check-out A Guide to Hiring Independent Contractors in Washington State (F101-063-000) for additional information.
