How can I differentiate the notifications I receive as a Trusted Contact from notifications for my own CPF account?
You can look out for the label in the notifications sent to you:
SMS Notifications: Begins with “(To Trusted Contact)”
Email: Contains “You are receiving this notification as an appointed Trusted Contact”
Push Notifications via CPF Mobile app (if enabled): Contains “You are receiving this notification as an appointed Trusted Contact of <Name of your appointer>”
