How to Block No Caller ID Calls on iPhone: Tips to Protect Your Caller ID

Do you get annoyed by unwanted calls from unknown numbers or no caller ID on your iPhone? If so, you are not the only one. Many iPhone users have reported receiving spam calls, prank calls, or telemarketing calls from numbers that are either hidden or not in their contacts. These calls can be very disturbing, especially if they happen frequently or at inconvenient times.

Fortunately, there are some ways to block no caller ID on iPhone and stop these annoying calls from bothering you. In this article, we will show you some methods to block no caller ID on iPhone, and explain the pros and cons of each one. We will also give you some tips on how to identify and avoid scam calls, and how to report them if you receive them.

Ultimate Guide: Blocking No Caller ID Calls on iPhone for Enhanced Privacy

No caller ID calls occur when someone blocks their phone number from being visible on your caller ID display. Usually, private callers are trying to keep their identity secret for privacy or to avoid identification. However, blocking caller ID is also a tactic commonly used by telemarketers and scammers hoping you’ll answer out of curiosity. The bottom line is that calls with no caller ID rarely mean anything good!

Differences Between No Caller ID and Unknown Caller: It’s important to understand the difference between a “no caller ID” and an “unknown caller”. A no caller ID call explicitly masks the caller’s information. Meanwhile, an unknown caller provided an ID but it’s not in your contacts – so their number appears unfamiliar to your device.

Possible Causes of No Caller ID on iPhone

Before we show you how to block no caller ID on iPhone, let’s first understand why you might receive calls from unknown numbers or no caller ID on your iPhone. There are several possible causes, such as:

  • The caller has intentionally blocked their number or used a spoofing service to hide their identity. This can be done by dialing *67 before the number, or by using an app or a website that allows them to change their caller ID.
  • The caller is using a VoIP service or a burner phone that does not have a registered number or a caller ID. This can be done by using an app or a website that allows them to make free or cheap calls over the internet.
  • The caller is from a different country or a different network that does not support caller ID or has a different format. This can happen when you travel abroad or receive calls from international numbers.
  • The caller is from a restricted or private number that does not display caller ID for security or privacy reasons. This can happen when you receive calls from government agencies, law enforcement, or emergency services.

Depending on the cause of the no caller ID on your iPhone, you might have different options to block it. Let’s see what they are.

Then find the contact, scroll to “Block this Caller” and select it to prevent rings from private numbers.
