Medical Mutual alerted nearly 1,600 customers that their Social Security Numbers were part of an 11-digit code inadvertently printed on postcards mailed to their homes recently. The company sent letters to the affected customers and has offered a credit-monitoring service for one year at no cost to help protect them from potential issues resulting from the incident.
Medical Mutual said it takes the privacy of its customers seriously and apologizes for any inconvenience the incident might have caused. Consequently, the company has tightened its internal procedures to help prevent this type of situation from happening again.
Medical Mutual said that, on October 16 and 17, it mailed educational postcards. On October 18, the company discovered that the cards were mailed with nine-digit Social Security Numbers included as part of an 11-digit code above the recipients’ names and addresses. A customer who received the postcard notified Medical Mutual of the issue.
