About MassNotify

MassNotify is a new service developed in partnership with Google and Apple to help slow the spread of COVID-19.

  • By opting in, your device will share anonymous codes with other MassNotify users using your phone’s Bluetooth.
  • MassNotify codes contain no personal information or location data and are completely anonymous.
  • If another user you’ve been near tests positive for COVID-19 within a 14-day period, you will be notified. If you test positive, you can easily and anonymously notify others to stop the spread of COVID-19.

Along with wearing masks and keeping a safe distance, MassNotify is another way to keep ourselves and our communities safe from the spread of COVID-19.
