Look up a business or professional license

Search business and professional licenses

Find out:

  • If we’ve issued a professional license to a person or business.
  • If their license is active.
  • When their license expires.
  • If they have professional license violations.

You can search by:

  • Name
  • License number
  • Type of license
  • Location — Note: Some professional licenses don’t list a street address and may not show up if you search just by location.
