MO/Notify is a service that lets you know if you’ve been in contact with someone who tests positive for COVID-19, even if you don’t know them.

Is that allergies, a seasonal cold or COVID-19? Knowing you’ve been exposed could keep you from harming yourself or others by dismissing your symptoms.

Users who test positive for Covid-19 should obtain a pin code in order to trigger notifications to other users. This process must be initiated on the same device on which you run MO/Notify.

If you are currently viewing this page on the device where you run MO/Notify, you may click the button below to obtain a code to enter a positive test result.
