Blocking a number on your Apple Watch can be essential for maintaining your peace, especially when dealing with unwanted calls or messages. While the Apple Watch doesn’t directly offer a way to block numbers, there are effective methods to manage this using your paired iPhone. Let’s explore how you can do this.

Understanding the Apple Watch’s Limitations

The Apple Watch works in tandem with your iPhone, and many of its functions, including call and message blocking, rely on settings applied on the iPhone.

Blocking Numbers via iPhone

To block a number effectively so that it also applies to your Apple Watch, follow these steps on your iPhone:

1. Block from Recent Calls

  • Open the ‘Phone’ app on your iPhone.
  • Navigate to ‘Recents’.
  • Find the number you want to block, then tap the ‘i’ icon next to it.
  • Scroll down and select ‘Block this Caller’.

2. Block from Messages

  • Open the ‘Messages’ app.
  • Open the conversation with the number you want to block.
  • Tap the contact at the top and select ‘info’.
  • Tap on ‘info’ again, then choose ‘Block this Caller’.

3. Block from Contacts

  • Go to your ‘Contacts’ app.
  • Select the contact you wish to block.
  • Scroll down and tap on ‘Block this Caller’.

Blocking Effects on Apple Watch

Once you have blocked a number on your iPhone:

  • Calls: The blocked number will not be able to call you on your iPhone or your Apple Watch.
  • Messages: Text messages from the blocked number will not appear on your iPhone or your Apple Watch.

Managing Blocked Numbers

You can view and manage your blocked numbers list by going to:

  • Settings > Phone > Blocked Contacts on your iPhone.

Synchronization with Apple Watch

  • Ensure your Apple Watch is properly synced with your iPhone so that any changes made on the iPhone are reflected on the watch.

Limitations to Keep in Mind

  • Blocking a number on your iPhone will block it across all your Apple devices connected to the same iCloud account, including your Apple Watch.
  • The Apple Watch itself doesn’t have a separate blocking feature. All blocking actions need to be performed on the iPhone.


Blocking a number on your Apple Watch requires you to block the number on your paired iPhone. This process is straightforward and ensures that unwanted calls and messages are filtered out on both devices.


  1. Can I block a number directly on my Apple Watch? No, you need to block the number on your iPhone, which will then sync with your Apple Watch.
  2. Will blocking a number on my iPhone also block it on my Apple Watch? Yes, blocking a number on your iPhone will also block it on your Apple Watch.
  3. How can I manage my blocked numbers list? You can manage it through the ‘Settings’ > ‘Phone’ > ‘Blocked Contacts’ on your iPhone.
  4. What happens when I block a number on my iPhone? The blocked number won’t be able to call or send text messages to your iPhone or Apple Watch.
  5. Is it possible to unblock a number later? Yes, you can unblock a number anytime via the ‘Blocked Contacts’ section in your iPhone settings.
