Licensing Freedom Act

Executive Order 2017-06 required State agencies to submit a report to the Office of the Governor no later than July 1, 2018. The report was to assess whether the licensure requirements are necessary and in the public interest while providing recommendations for improvement, modification or elimination. The Board's report can be found here.



The Division has been made aware of scam artists who may target licensees. If you get a call, e-mail, text or other communication from an individual claiming to represent the Division of Occupational and Professional Licenses or the Board, here is some information to help you identify whether it is a scam:

The Boards and the Division WILL NOT:

• Ask for personal information that does not relate to your license renewal (such as your credit card number or bank account number)
• Demand immediate payment on fines that are not yet due
• Ask for or accept prepaid cards such as Green Dot MoneyPak
• Offer to alter a disciplinary order that has already been entered by the Board
• Ask for or take payments over the phone

The Boards and the Division WILL:

• Send renewal notices in the mail
• Take payments on the official website at
