Check a License in Massachusetts

The Division of Occupational Licensure (DOL) oversees 26 boards, which license and regulate more than 100 trades and professions in Massachusetts. You may check that a business or individual the DOL oversees has a valid license or permit using one of our online portals. 

If your business or individuals in your business need to be licensed by the state, check the requirements in the corresponding state Occupational Board.
