WhatsApp is one of the most popular messaging apps in the world, with over 2 billion users globally. One of the key features that makes WhatsApp so useful is its ability to send push notifications to users about new messages, calls, status updates, and other activity. But does WhatsApp actually have push notifications and how do they work?
What are push notifications?
Push notifications are messages that apps can send to users even when the app is closed or running in the background. They allow apps to alert users about new information or events in real-time.
For example, when you get a new message on WhatsApp, a push notification is sent to your device to let you know you’ve received a new message. You don’t need to have the WhatsApp app open to get the notification.
Push notifications are different from other notification types like SMS or email. With SMS or email, the notifications are sent by a central server to your device. With push notifications, the notifications originate from the app itself on a remote server and are pushed directly to your device.
This allows for faster and real-time delivery of notifications. It also allows apps to customize the notifications with sounds, badges, banners, and other formatting options.
Does WhatsApp use push notifications?
Yes, WhatsApp uses push notifications to alert users about new messages, calls, status updates, and other activity. This is what enables WhatsApp to deliver notifications in real-time without you needing to have the app open.
Here’s an overview of the different types of push notifications WhatsApp uses:
- New messages – Get notified when you receive a new message in any chat or group.
- Missed calls – Get notified if you miss a voice or video call on WhatsApp.
- New status updates – Get notified when a contact shares a new status update (photo, video, text, etc).
- New group notifications – Get notified when someone adds you to a group or when a group is renamed.
- Two-step verification – Get a notification if an attempt is made to verify your number on a new device.
As you can see, WhatsApp relies heavily on push notifications to keep users connected and engaged in real-time messaging. Without push notifications, you’d constantly have to open the app to check for new messages or activity. Notifications bring the updates right to your home screen.
How do WhatsApp’s push notifications work?
WhatsApp’s push notifications work through an efficient behind-the-scenes communication between your device, the WhatsApp servers, and push notification services like Firebase Cloud Messaging (FCM).
Here is a simplified overview of the steps:
- You install WhatsApp on your device and register your phone number. WhatsApp gets your device token from FCM (for Android devices).
- When someone sends you a WhatsApp message, the message data goes to WhatsApp’s servers.
- The WhatsApp servers identify which device token to send the push notification based on the recipient phone number.
- The notification payload is sent through FCM to the target device token.
- FCM routes the notification to your device, which wakes up WhatsApp to display the notification if the app is closed.
- When you tap the notification, it launches WhatsApp to the relevant message thread.
This entire process takes just seconds from the time the message is sent to it reaching your device as a notification. The direct communication between WhatsApp, FCM, and your device enables real-time notifications.
Additionally, WhatsApp optimizes notifications through features like batching. This bundles multiple notifications into one to prevent notification spam. WhatsApp also has a notifications settings section where you control notification sounds, visibility, and more.
Why are WhatsApp notifications important?
WhatsApp notifications play an important role in the overall messaging experience. Here are some of the key benefits:
- Real-time connection – Notifications facilitate real-time communication by instantly alerting you about messages.
- User engagement – Notifications keep users engaged with timely updates from contacts.
- Prevents missing messages – You won’t miss important messages if your app is closed.
- Context – Notifications give context with messenger names, message previews, etc.
- Convenience – No need to manually check the app all the time for new messages.
- Customization – Granular notification controls let you customize on a per-chat basis.
Without notifications, WhatsApp would lose its real-time appeal for users who expect messaging apps to deliver updates in a timely manner. Notifications make the user experience smooth and convenient.
WhatsApp notification customization
WhatsApp provides great control over notification settings so you can customize them as per your preferences. Here are some of the notification settings you can tweak:
- Notification tone – Set a custom notification sound for WhatsApp notifications.
- Vibration – Toggle vibration on/off for new notifications.
- Popup notification – Enable popup notifications for new messages.
- Show previews – Show message previews or hide message contents for privacy.
- Notification indicators – Show notification dots, use LED light, or enable icon badges for unread counts.
- Priority notifications – Set notifications as urgent to override Do Not Disturb.
- Light notification – Enable a less intrusive light notification for specific chats.
You can access these notification settings by going into WhatsApp Settings > Notifications. There are also per-chat notification controls to disable notifications for specific chats.
Using these settings, you can really customize WhatsApp notifications to match your preferences and ensure you get notified only about the most important messages.

In some cases, you may not get WhatsApp notifications properly on your device. Here are some tips to troubleshoot and fix WhatsApp notification issues:
