What is the purpose of substitute notice in breach notification laws?

The purpose of substitute notice in breach notification laws is to ensure that affected individuals receive notification of a data breach even when their contact information is insufficient or outdated. This is particularly important because timely notification of a breach is key to protecting individuals from potential harm, such as identity theft or fraud.

In situations where a company is unable to reach some individuals directly through traditional means of notification, substitute notice offers alternative methods, which may include methods like public announcements or notices on websites. This approach helps ensure that as many affected individuals as possible are made aware of the breach and can take necessary actions to safeguard their personal information. Substitute notice is a critical component of breach notification requirements designed to prioritize consumer awareness and protection in the event of a security incident.
