How to Silence and Block Unidentified Callers on iPhone

Receiving calls from unknown numbers or callers without an ID can be both annoying and unsettling. Fortunately, the iPhone offers several built-in features to help block or silence these calls. In this guide, we’ll explore three effective methods to block “No Caller ID” calls on your iPhone.

1. Silence Unknown Callers

One of the simplest ways to block unknown or unidentified callers is by using the “Silence Unknown Callers” feature. This option automatically silences calls from numbers that are not in your contacts, sending them directly to voicemail.

Here’s how to enable it:

1. Open the Settings app on your iPhone.
2. Scroll down and tap on Phone.
3. Select Silence Unknown Callers.
4. Toggle the slider to the on/green position.

Once activated, all calls from numbers that are not saved in your contacts will be silenced and sent to voicemail, ensuring that only familiar contacts can reach you directly.

2. Use Do Not Disturb to Block Calls

The “Do Not Disturb” feature on the iPhone is designed to block notifications, calls, and alerts during specific times or conditions. However, it can also be used to block or screen calls from unknown numbers.

Follow these steps to use Do Not Disturb for blocking calls:

1. Open the Settings app on your iPhone.
2. Tap on Focus.
3. Select Do Not Disturb and toggle the slider to on/green.
4. Under the Allowed Notifications section, tap People.
5. In the Also Allow section, select Calls From.
6. Choose All Contacts or Contacts Only.

With this setup, you will only receive calls from people saved in your contacts. All other calls will be silenced and sent to voicemail, allowing you to focus without interruptions.

3. Block No Caller ID Calls Using a Fake Contact

This creative method involves creating a fake contact specifically for “No Caller ID” and then blocking it. This trick takes advantage of how the iPhone handles blocked contacts.

Here’s how to set it up:

1. Open the Contacts app on your iPhone.
2. Tap the + (Plus) icon to create a new contact.
3. In the First name field, enter “No Caller ID.”
4. Tap Add phone and enter “000-000-0000” as the phone number.
5. Tap Done to save the contact.

Now, to block this contact:

1. Go to the Settings app.
2. Tap on Phone.
3. Select Blocked Contacts.
4. Scroll to the bottom and tap Add New.
5. Find and select the “No Caller ID” contact you just created.

With this method, any call from a hidden number (a common tactic used by spammers) will be sent directly to voicemail, effectively blocking them from disturbing you.

Additional Tips

If you’re still getting unwanted calls after using these methods, consider contacting your phone carrier. Many carriers offer services that block spam calls and robocalls for an additional fee. Additionally, you can register your number with the national Do Not Call Registry if you’re in the United States, which can help reduce the number of telemarketing calls you receive.

FAQs

What does “No Caller ID” mean?
A call labeled as “No Caller ID” means the caller is deliberately hiding their number. This is often done to avoid being blocked or tracked, commonly associated with scam calls.

How can I identify a caller with no caller ID?
Unfortunately, it’s difficult to trace calls from hidden numbers since the caller is masking their identity. The best course of action is to block these calls using the methods outlined above or simply avoid answering calls from unknown numbers.

By following these steps, you can take control of your iPhone and prevent unwanted calls from disrupting your day.
