Missouri Revised Statutes Title XXXIX. Conduct of Public Business § 610.035. State entity not to disclose Social Security number, exceptions

No state entity shall publicly disclose any Social Security number of a living person unless such disclosure is permitted by federal law, federal regulation or state law or unless such disclosure is authorized by the holder of that Social Security number or unless such disclosure is for use in connection with any civil, criminal, administrative or arbitral proceeding in any federal, state or local court or agency or before any self-regulatory body, including the service of process, investigation in anticipation of litigation and the execution or enforcement of judgments and orders, or pursuant to an order of a federal, state or local court. Notwithstanding any other provision of law to the contrary, the disclosure of Social Security numbers of deceased persons shall be lawful, provided that the state agency disclosing the information knows of no reason why such disclosure would prove detrimental to the deceased individual's estate or harmful to the deceased individual's living relatives. For the purposes of this section, “publicly disclose” shall not include the use of any Social Security number by any state entity in the performance of any statutory or constitutional duty or power or the disclosure of any Social Security number to another state entity, political subdivision, agency of the federal government, agency of another state or any private person or entity acting on behalf of, or in cooperation with, a state entity. Any person or entity receiving a Social Security number from any entity shall be subject to the same confidentiality provisions as the disclosing entity. For purposes of this section, “state entity” means any state department, division, agency, bureau, board, commission, employee or any agent thereof. When responding to any requests for public information pursuant to this chapter, any costs incurred by any state entity complying with the provisions of this section may be charged to the requester of such information.
