What Township Officials Need to Know About Complying With the Social Security Number Privacy Act (.pdf)

Under Michigan law, any governmental unit (including townships), business, organization or person using Social Security numbers for any purpose must take steps to maintain the confidentiality of those numbers and to notify any person whose Social Security number has been involved in a security breach.

Beginning January 1, 2006, any township that uses Social Security numbers in the ordinary course of township business—including employee identification, payroll reporting, benefits accounts, medical records, voter registration, law enforcement, bank accounts or computer passwords—is required to comply with the act and adopt a privacy policy.
