A user having multiple electronic devices may receive notifications at each of the devices. When it is determined that a first device is in an active state and that a notification has been viewed on that device, an indication that the notification has been viewed may be communicated by the first device to a synchronization server. It may then be determined whether the viewed notification is also present on one or more of the user's other devices. Based on the determination, an indication that the notification has been viewed may be sent from the synchronization server to each of the user's devices on which the notification is present. Upon receipt of the indication from the synchronization server, the viewed notification may be removed from each of the devices, thereby avoiding a redundant display of the notification on multiple devices.
