The division of professional registration shall maintain, for each board in the division, a registry of each person holding a current license, permit, or certificate issued by that board. The registry shall contain the name, Social Security number, and address of each person licensed or registered together with other relevant information as determined by the board. The registry for each board shall at all times be available to the board and copies shall be supplied to the board on request. Copies of the registry, except for the registrant’s Social Security number, shall be available from the division or the board to any individual who pays the reasonable copying cost. Any individual may copy the registry during regular business hours. The information in the registry shall be furnished upon request to the family support division. Questions concerning the currency of license of any individual shall be answered, without charge, by the appropriate board. Each year each board may publish, or cause to be published, a directory containing the name and address of each person licensed or registered for the current year together with any other information the board deems necessary. Any expense incurred by the state relating to such publication shall be charged to the board. An official copy of any such publication shall be filed with the director.
