Verification Overview & Key Takeaways: How to Check Official Credentials

HomeCrafto displays source records with different scopes, including licenses, registrations, municipal permits and community records. A source entry is not proof of qualification for your job. Before signing a work order or paying a deposit, homeowners should confirm that the contractor’s credential number is active, verify that the license classification covers the specific trade scope required for the job, and request a current Certificate of Insurance (COI) directly from the issuing insurance carrier. Independent verification protects your property and ensures compliance with local building codes.

How do you verify a contractor license number and insurance on official portals (FAQ)?

You can verify active license standing and consumer protection rules directly through official government portals, including Washington L&I Contractor Verify, the California Contractors State License Board (CSLB), the Connecticut eLicense Portal, USA.gov State Consumer Protection Offices, and FTC Home Improvement Consumer Guidance. Always confirm municipal permit requirements with your local building department before work begins.
