How to verify a license

  1. Ask the business for its license number and the exact name the license is issued to.
  2. Search the OCILB lookup via the Department of Commerce and match the name to the business you are hiring.
  3. Confirm the classification covers your type of work, the status is active, and the expiration date is in the future.
  4. Check insurance separately: ask for a certificate of insurance. A license and insurance are different checks.
